It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

These version numbers are available for use as autoconf -variables (see the library 'Makefile.am' files and -'packages/sofia-sip.spec.in'). - -All changes to the library versions should be marked to the -appropriate library 'ChangeLog' file.

For instance, the functions within http parser module @b http -have prefix @c http_. Identifiers composed of multiple words have an -underscore "_" between the words, the words themselves are in lower -case. For instance, http_request_create(). - -Macros should be in upper case. File names should be in lower case using -underscore as delimiter if needed. - -Normal typedefs have suffix @c _t, however, function types have suffix @c -_f. The enum names also sometimes have @c _e, struct names have @c _s and -union names @c _u. - -It is recommended that type itself is typedef'ed, not a pointer to the -type. It should be clear from variable declaration if the variable is a -pointer or not. - -@code -typedef struct foo_s foo_t; -typedef int f_fun(foo_t *f, char const *s); -@endcode - -Struct and union members should have common prefix. For instance, -@code -struct foo_s { - int f_len; - char *f_name; - fun_f *f_fun; -}; -@endcode - -This prefix makes it easier to find where members are used. - -@section formatting Indenting and Formatting code - -Indentation in Sofia-SIP C code generally follows the @e K&R style with indent -of 2 characters (so you can use the default "GNU" c-style in Emacs). The -maximum line length should be 80 characters. - -For example, - -@code -void kluge(int foo) -{ - if (foo) { - bar(); - } - else { - switch (baz()) { - case a: - eeny(); - break; - case b: - meeny(); - break; - default: - moe(); - break; - } - } -} -@endcode - -The default indentation can be achieved with GNU indent with options -@code --nbad -bap -bbo -nbc -br -brs -c33 -cd33 -ncdb -ce -ci2 -cli0 -cp33 -cs --d0 -di1 -nfc1 -nfca -hnl -i2 -ip0 -l79 -lp -npcs -nprs -npsl -saf -sai --saw -nsc -nsob -nss -@endcode - -Loops without condition use @c for @c (;;) instead of @c while @c (1). - -@code - for (;;) { - foo(); - if (bar()) - break; - baz(); - } -@endcode - -There should be whitespace on both sides of infix operators, except -. or ->, which require no space, or -, (comma) which requires space only after).

All core modules are -(or at least should be) written in ANSI C 89 with some ANSI C 99 -features. If there are platform specific parts, they are collected to -separate C files and isolated from the rest of the software with a -wrapper interface. - -SU module handles abstraction to OS specific functionality such as -memory management, sockets, threads and time functions. - -@subsection ansi_99 ANSI C 99 features - -The following ANSI C 99 features are to be used in Sofia-SIP software: -- Integer types -- functions va_copy() and snprintf() - -The following ANSI C 99 features shall not be used in Sofia-SIP software: -- definition of a variable in the middle of function code. - (so always define your variables in the beginning of the block) - -@subsection port_ints Integer Types - -As you should know, the length of native storage size depends on hardware, -OS and compiler. This means in practice that the length of int or long is -not necessarily 32 bits. As a consequence, you need to make sure that the -value you intend to store in the int, can actually fit in int on different -platforms. As a rule of thumb, if the integer value can exceed 8 bits, you -should use types that have a defined length. - -Nevertheless its OK to use native integer types if you bear in mind -what was said above. The original reason for having only native -data type was performance. The int type is always stored in the -fastest (and usually biggest size) possible. - -Never assume anything on the length of the type. Alway use sizeof() -operator to find out the length. - -C 99 standard defines the following fixed length data types: - -- int64_t -- uint64_t -- int32_t -- uint32_t -- int16_t -- uint16_t -- int8_t -- uint8_t - -To use these data types you must include the header, which -takes care of including correct file. If @b su includes are not available, -you must include the following code segment to each file where you plan to -use them: - -@code -#if HAVE_STDINT_H -#include -#elif HAVE_INTTYPES_H -#include -#else -#error Define HAVE_STDINT_H as 1 if you have , \ - or HAVE_INTTYPES_H if you have -#endif -@endcode - -@subsection port_byte_sex Byte order - -The host byte order on different platforms vary. When you do only -local processing, need not to worry about the byte order. But as -soon as you start writing code that send or receives anything to -the network, you need to start worrying. - -If you wish to convert the byte order, it is simply done by calling -one the following functions: - -The htonl() function converts the unsigned integer hostlong from -host byte order to network byte order. - -The htons() function converts the unsigned short integer hostshort -from host byte order to network byte order. - -The ntohl() function converts the unsigned integer netlong from -network byte order to host byte order. - -The ntohs() function converts the unsigned short integer netshort -from network byte order to host byte order. - -You need to include or to use these functions. - -@subsection port_struct Packing structures - -By default, compilers usually arrange structures so that they are -quick to access. This means that most fields in the structure start -at the 32 bit boundary. If you need to conserve memory, you may use -structure packing. - -To tell the compiler that you only need certain amount of bits to -store a variable, you can use bit-fields. Compiler may or may not -pack the bit-fields. - -@code -struct foo { - unsigned bar:5; - unsigned foo:2; - unsigned :0; - int something; -} -@endcode - -If compiler decides to pack this structure, this code generates a -structure that has @a bar and @a foo in the first seven bits, and then -@a something beginning from the next 32 bit boundary. - -One problem arises when using packed bit-fields: on ARM it is -generally not possible to access a 32 bit field that does not start from -the 32-bit boundary. Hence the example has the :0 padding member in the -structure. Seems handy but beware: initialization of this structure fails -on some ARM gcc compilers. (Ask Kai Vehmanen for details). - -A way to force packing of a structure is to use preprocessor -directive @c @#pragma(pack). This directive is compiler specific, so if -you plan to write truly portable code, you cannot use it. We have -used it in some parts of the Sofia-SIP though. Only alternative is to -write functions that fetch the desired bits from a 32 bit field -with bit operations; not very handy and error prone. - -The same aligment problem also arises if you cast for example char -buffer to a int32_t. You can only read int32_t from the 32bit boundary -on ARM platform. So be careful. - -As a conclusion, when using bit-fields and stucture packing, beware -of the pitfalls. If you don't really need to use them (as in parsing -binary protocols), don't use them. - -@section file_organization File and Directory Structure - -A Sofia-SIP library module can be defined as a subdirectory under the -libsofia-sip-ua directory hierarchy that contains a file \.docs -(where the \ of course referes to the actual name of -the module). - -In case you like to start developing a new module, please -contact Sofia-SIP development team so that they can help you to set up -the basic module for you. - -An overview of the contents of a module directory: - - file \.docs \n - Main documentation file for the module. See @ref module_docs - for more information - - subdirectory pictures \n - Contains any pictures/images - that are needed by the module documentation. The - file formats to use are GIF (for html pages) and - EPS (for latex). If some program (e.g. MS Visio) is - used to create the pictures, also the original - files must be stored here.\n - (Note that old modules may have "images" subdirectory instead of - "pictures") - - files Makefile.am \n - See section @ref build "dealing with GNU Autotools" below. - - (optionally) source code file(s) of the module and module tests. - The source code file(s) can also be located in subdirectories if necesary. - - -@section oo_with_c Writing Object-Oriented Code - -While C does not provide any special object-oriented features on its own, it -is possible to program in object-oriented way using C, too. Sofia code make -use of many object-oriented features while being written entirely in C. - -@subsection oo_hiding Data Hiding - -Data hiding is a practice that makes separation between two modules very -clear. Outside code cannot directly access the data within a module, but it -has to use functions provided for that purpose. Data hiding also makes it -easier to define a protocol between two objects - all communication happens -using function calls. - -How to implement data hiding in C? Easiest answer is to only declare data -structures in the header files, not to define them. We have a typedef #msg_t -for @link msg_s struct msg_s @endlink in , but the actual -structure is defined in "msg_internal.h". Programs outside @b msg module -does not have access to the @link msg_s struct msg_s @endlink, but they have -to to access the #msg_t object through method functions provided in -. The @b msg implementation is also free to change the -internal layout of the structure, only keeping the function interface -unmodified. - -@subsection oo_interface Interfaces - -Abstract interface is another object-oriented practice used in Sofia. Parser -headers, defined in , is a good example of abstract -interface. The type for message headers, #msg_header_t, is defined using two -C structures @link msg_common_s struct msg_common_s @endlink -(#msg_common_t), and @link msg_hclass_s struct msg_hclass_s @endlink -(#msg_hclass_t). - -Abstract interface is achieved using virtual function table in #msg_hclass_t -structure, bit like C++ typically implements abstract classes and virtual -functions. For implemenation of each header, the function table is -initialized with functions responsible for decoding, encoding and -manipulating the header structure. Unlike C++, the class of the object -(#msg_hclass_t) is represented by a real data structure which also contains -header-specific data, like header name. - -@dontinclude sip_basic.c -@skipline msg_hclass_t sip_contact_class -@skip {{ -@until }}; - -@subsection oo_derived Inheritance and Derived Objects - -Inheritance is a object-oriented practice that has limited use in Sofia. -Most common example of inheritance is use of #su_home_t. Many objects are -derived from #su_home_t, which means that they can use the various -home-based memory management functions from . - -In this sence, inheritance means that a pointer to a derived object can be -casted as a pointer to a base object. In other words, the derived object -must have the base object at the beginning of its memory area: - -@code -struct derived -{ - struct base base[1]; - int extra; - char *data; -}; -@endcode - -There are three alternatives to cast a pointer to derived to a pointer to -base: -@code -struct base *base1 = (struct base *)derived; -struct base *base2 = &derived->base; -struct base *base3 = derived->base; -@endcode -The third alternative works because base was used as a 1-element array. - -@subsection oo_templates Templates - -There are a few template types implemented as macros in Sofia libraries. -They include hash table, defined in , which can be used -to define hash tables types and accessor functions for different object, and -red-black tree, defined in . - -@section memory Memory Management - -The home-based memory management is useful when a lot of memory blocks are -allocated for given task. The allocations are done via the memory home, -which keeps a reference to each allocated memory block. When the memory -home is then freed, it will free all memory blocks to which it has -reference. This simplifies application logic because application code does -not need to keep track of the allocated memory and free every allocated block -separately. - -See documentation of and @ref su_alloc "memory managment tutorial" -for more information of memory management services. - -@subsection contextdata Memory management of context data - -A typical example of use of a memory home is to have a memory home structure -(#su_home_t) as part of operation context information structure. - -@code - /* context info structure */ - struct context { - su_home_t ctx_home[1]; /* memory home */ - other_t *ctx_other_stuff; /* example of memory areas */ - ... - }; - - /* context pointer */ - struct context *ctx; - - /* Allocate memory for context structure and initialize memory home */ - ctx = su_home_clone(NULL, sizeof (struct context)); - - /* Allocate memory and register it with memory home */ - ctx->ctx_other_stuff = su_zalloc(ctx->ctx_home, sizeof(other_t)); - - ... processing and allocating more memory ... - - /* Release registered memory areas, home, and context structure */ - su_home_zap(ctx->ctx_home); - -@endcode - -@subsection combining Combining allocations - -Another place where home-based memory management makes programmers -life easier is case where a sub-procedure makes multiple memory allocations -and, in case the sub-procedure fails, all the allocations must be released -and, in case the sub-procedure is succesfull, all allocations must be -controlled by upper level memory management. - -@code - /* example sub-procedure. top_home is upper-level memory home */ - int sub_procedure( su_home_t *top_home, ... ) - { - su_home_t temphome[1] = { SU_HOME_INIT(temphome) }; - - ... allocations and other processing ... - - /* was processing successfull ? */ - if (success) { - /* ok -> move registered allocated memory to upper level memory home */ - su_home_move( top_home, temphome ); - } - /* destroy temporary memory home (and registered allocations) */ - /* Note than in case processing was succesfull the memory */ - /* registrations were already moved to upper level home. */ - su_home_deinit(temphome); - - /* return ok/not-ok */ - return success; - } -@endcode - -@section testing Testing Your Code - -See for example of how to write module tests with macros provided -by Sofia. - -Here are some ideas of what you should test: -- "Smoke test" \n - See that the module compiles, links and executes. -- Module API functions should be tested with\n - - valid args - - not valid args -- Aim for 100% line coverage\n - (If there is a line of code that you have not tested, you don't know - if its working.) \n - For selected part of code you should also aim for - 100% branch/path coverage.\n - But be anyway reasonable with these because in practise complete - coverage is next to impossible to achive (so 80% is ok in practise). -- Create test to check assumptions and/or tricks used in code.\n - For example if you rely on some compiler feature, create a test that - will fail with a compiler that does not have that feature. - -@subsection check Running Module Tests - -Automake, which is used to build Sofia SIP, has builtin -support for unit tests. To add an automatically run test to your module, -you just have to add the following few lines to your module's Makefile.am -(of course, you have to write the test programs, too): - -@code -TESTS = test_foo test_bar - -check_PROGRAMS = test_foo test_bar - -test_foo_SOURCES = foo.c foo.h -test_foo_LDADD = -L. -lmy - -test_bar_SOURCES = bar.c bar.h -test_foo_LDADD = -L. -lmy -@endcode - -Each test program should either return zero for success or a non-zero -error code in its main function. Now when you run "make check", -@b my_test_foo and @b my_test_bar will be built and then run. -Make will print a -summary of how the tests went. As these tests are run from the build -system, the tests must be non-interactive (no questions asked) and not -rely on any files that are not in version control system. - -Sofia SIP's top-level makefile contains a recursive check target, so -you can use "cd sofia-sip ; make check" to run all the existing tests -with a single command. - -@section build Dealing with GNU Autotools - -Sofia-SIP build system is based on the GNU tools automake, autoconf and -libtool.

These macros, along with all other macros used by @b configure.ac, are -copied into the module-specific @b aclocal.m4 file by an utility called -aclocal. - -Contact Sofia-SIP development team, if you need changes to these files. - -@subsection aclocal_m4 aclocal.m4 - -The aclocal.m4 contains the definitions of the autoconf macros used in -@b configure.ac. - -This file is generated by aclocal command. - -@subsection Makefile_am Makefile.am - -Makefile.am is where you define what programs and libraries should -be built, and also what source files are needed to create them. -When you run automake, it creates the file Makefile.in. - -This file is created by the developer of the module. - -@subsection configure configure - -When you run configure script, it performs all the checks defined in -@b configure.ac and then replaces all @b xxx.in files with equivalent -@b xxx files. All @c @@FOO@@ variables in the source @b *.in files are -replaced with values found during the configuration process. For instance -the variable @c @@srcdir@@ in @b Makefile.in is replaced in @b Makefile -with the source directory path (useful when compiling outside the main -source tree). - -This file is generated by autoconf command. - -@subsection config_status config.status - -This script stores the last parameters given to configre command. -If necessary you can rerun the last given configure script (with given -parameters) by using command "./config.status -r" or -"./config.status --recheck". - -This file is generated by configure script. - -@subsection config_cache config.cache - -This file contains results of the various checks that configure script -performed. In case the configure script failed, you might try to -delete this file and run the configure script again. - -This file is generated by configure script. - -@subsection Makefile Makefile - -The @b Makefile contains the actual rules how to build the target -libraries and program.

The -detail of the debugging output is determined by the debugging level. The -level is usually module-specific and it can be modified by module-specific -environment variable. There is also a default level for all modules, -controlled by environment variable #SOFIA_DEBUG. - -The environment variables controlling the logging and other debug output are -as follows: -- #SOFIA_DEBUG Default debug level (0..9) -- #NUA_DEBUG User Agent engine (nua) debug level (0..9) -- #SOA_DEBUG SDP Offer/Answer engine (soa) debug level (0..9) -- #NEA_DEBUG Event engine (nea) debug level (0..9) -- #IPTSEC_DEBUG HTTP/SIP autentication module debug level (0..9) -- #NTA_DEBUG Transaction engine debug level (0..9) -- #TPORT_DEBUG Transport event debug level (0..9) - - #TPORT_LOG If set, print out all parsed SIP messages on transport layer - - #TPORT_DUMP Filename for dumping unparsed messages from transport -- #SU_DEBUG su module debug level (0..9) - -The defined debug output levels are: -- 0 SU_DEBUG_0() - fatal errors, panic -- 1 SU_DEBUG_1() - critical errors, minimal progress at subsystem level -- 2 SU_DEBUG_2() - non-critical errors -- 3 SU_DEBUG_3() - warnings, progress messages -- 5 SU_DEBUG_5() - signaling protocol actions (incoming packets, ...) -- 7 SU_DEBUG_7() - media protocol actions (incoming packets, ...) -- 9 SU_DEBUG_9() - entering/exiting functions, very verbatim progress - -In addition to the macros mentioned above, there is also functions for -printing logging messages: -- su_llog(), su_vllog() -- su_perror(), su_perror2() - -The log level can be set (to a level defined in a configuration file, for -instance) with following functions -- su_log_set_level(), su_log_soft_set_level() - -The log output can be redirected to, e.g., system log or loggin server, with -su_log_redirect(). - -*/ diff --git a/libs/sofia-sip/libsofia-sip-ua/docs/pictures/SIP_basic_incoming_operation.eps

These -protocol-specific header files include , , and -. For each header, there is defined a @em header @em class -structure, some standard functions, and tags for including them in tag -lists. - -As a convention, all the identifiers for SIP headers start with prefix @c -sip and all the macros with @c SIP. Same thing holds for HTTP, too: it -uses prefix @c http. However, the MIME headers -and the functions related to them are defined within the @b msg module and -they use prefix @c msg. If a SIP or HTTP header uses a structure -defined in , there is a typedef suitable for the particular -protocol, for example @b Accept header is defined multiple times: - -@code -typedef struct msg_accept_s sip_accept_t; -typedef struct msg_accept_s http_accept_t; -@endcode - -For header @e X of protocol @e NS, there are types, functions, macros and -header class as follows: - - - @c ns_X_t is the structure used to store parsed header, - - @c ns_hclass_t @c ns_X_class[] contains the @em header @em class - for header X, - - @c NS_X_INIT() initializes a static instance of @c ns_X_t, - - @c ns_X_init() initializes a dynamic instance of @c ns_X_t, - - @c ns_is_X() tests if header object is instance of header X, - - @c ns_X_make() creates a header X object by decoding given string, - - @c ns_X_format() creates a header X object by decoding given - @c printf() list, - - @c ns_X_dup() duplicates (deeply copies) the header X, - - @c ns_X_copy() copies the header X, - - @c NSTAG_X() is used include instance of @c ns_X_t in a tag list, and - - @c NSTAG_X_STR() is used to include string containing value header - in a tag list. - -The declarations of header tags and the prototypes for these functions can -be imported separately from the type definitions, for instance, the tags -related to SIP headers are declared in the include file -, and the header-specific functions in -. - -@section parser_intro Parsing Text Messages - -Sofia text parser follows @em recursive-descent principle. In other words, -it is a program that descends the syntax tree top-down recursively. -(All syntax trees have root at top and they grow downwards.) - -In the case of SIP, HTTP and other similar protocols, such a parser is very -efficient. The parser can choose between different forms based on each -token, as the protocol syntax is carefully designed so that it requires only -minimal scan-ahead. It is also easy to extend a recursive-descent parser via -a standard API, unlike, for instance, a LALR parser generated by @em Bison. - -The abstract message module @b msg contains a high-level parser engine that -drives the parsing process and invokes the protocol-specific parser for each -header. As there is no low-layer framing between the RFC822-style messages, -the parser considers any received data, be it a UDP datagram or a TCP -stream, as a @em byte @em stream. The protocol-specific parsers controls how -a byte stream is split into separate messages or if it consists of a single -message only. - -The parser engine works by separating stream into fragments, then passing -the fragment to a suitable parser. A fragment is a piece of message that is -parsed during a single step: the first line, each header, the empty line -between headers and message body, the message body. (In case of HTTP, the -message body can consists of multiple fragments known as chunks.) - -The parser starts by separating the first line (e.g., request or status -line) from the byte stream, then passing the line to the suitable parser. -After first line comes the message headers. The parser continues parsing -process by extracting headers, each on their own line, from the stream and -passing contents of each header to its parser. The message structure is -populated based on the parsing results. When an empty line - indicating end -of headers - is encountered, the control is passed to the protocol-specific -parser. Protocol-specific functions take care of extracting the possible -message body from the byte stream. - -After parsing process is completed, it can be given to the upper layers -(typically a protocol state machine). The parser continues processing the -stream and feeding the messages to protocol engine until the end of the -stream is reached. - -@image html sip-parser.gif Separating byte stream to messages -@image latex sip-parser.eps Separating byte stream to messages - -When the parsing process has completed, the first line, each header, -separator and the message body are all in their own fragment structure. The -fragments form a dual-linked list known as @e fragment @e chain as shown in -the above figure. The memory buffers for the message, the fragment chain, -and a whole lot of other stuff is held by the generic message type, #msg_t, -defined in . The internal structure of #msg_t is known only within @b -msg module and it is opaque to other modules. - -The @b msg parser engine also drives the reverse process, invoking the -encoding method of each fragment so that the whole outgoing message can be -encoded properly. - -@section msg_header_struct Message Header as a C struct - -Just separating headers from each other and from the message body is not -usually enough. When a header contains structured data, the header contents -should be converted to a form that is convenient to use from C programs. For -that purpose, the message parser needs a parsing function specific to each -individual header. This parsing function divides the contents of the header -into semantically meaningful segments and stores the result in the structure -specific to each header. - -The parser engine passes the fragment contents to the parsing function after -it has separated the fragment from the rest of the message. The parser -engine selects correct @e header @e class either by implication (in case of -first line), or it searches for the header class from the hash table using -the header name as the hash key. The @e header @e class contains a pointer -to the parsing function. The parser has also special header classes for -headers with errors and @e unknown headers, header with a name that is not -regocnized by the parser. - -For instance, the Accept header has following syntax: -@code - Accept = "Accept" ":" #( media-range [ accept-params ] ) - - media-range = ( "*" "/" "*" - | ( type "/" "*" ) - | ( type "/" subtype ) ) *( ";" parameter ) - - accept-params = ";" "q" "=" qvalue *( accept-extension ) - - accept-extension = ";" token [ "=" ( token | quoted-string ) ] -@endcode - -When an Accept header is parsed, the header parser function (msg_accept_d()) -separates the @e type, @e subtype, and each parameter in the list to -strings. The parsing result is assigned to a #msg_accept_t structure, which is -defined as follows: - -@code -typedef struct msg_accept_s -{ - msg_common_t ac_common[1]; //< Common fragment info - msg_accept_t *ac_next; //< Pointer to next Accept header - char const *ac_type; //< Pointer to type/subtype - char const *ac_subtype; //< Points after first slash in type - msg_param_t const *ac_params; //< List of parameters - msg_param_t ac_q; //< Value of q parameter -} -msg_accept_t; -@endcode - -The string containing the @e type is put into the @c ac_type field, the @e -subtype after slash in the can be found in the @c ac_subtype field, and the -list of @e accept-params (together with media-specific-parameters) is put in -the @c ac_params array. If there is a @e q parameter present, a pointer to -the @c qvalue is assigned to @c ac_q field. - -In the beginning of the header structure there are two boilerplate members. -The @c ac_common[1] contains information common to all message fragments. -The @c ac_next is a pointer to next header field with the same name, in case -a message contains multiple @b Accept headers or multiple comma-separated -header fields are located in a single line. - -@section msg_object_example Representing a Message as a C struct - -It is not enough to represent a message as a list of headers following each -other. The programmer also needs a convenient way to access certain headers -at the message level, for example, accessing directly the @b Accept header -instead of going through all headers and examining their name. The -structured view to the message is provided via a message-specific C struct. -In general, its type is msg_pub_t (it provides public view to message). The -protocol-specific type is #sip_t, #http_t or #msg_multipart_t for -SIP, HTTP and MIME, respectively. - -So, a single message is represented by two objects, first object (#msg_t) is -private to the @b msg module and opaque by an application programmer, second -(#sip_t, #http_t or #msg_multipart_t) is a public protocol-specific -structure accessible by all. - -@note The application programmer can obtain a pointer to the -protocol-specific structure from an #msg_t object using msg_public() -function. The msg_public() takes a protocol tag, a well-known identifier, as -its argument. The SIP, HTTP and MIME already define a wrapper around -msg_public(), for example, a #sip_t structure can be obtained with -sip_object() function (or macro). - -As an example, the #sip_t structure is defined as follows: -@code -typedef struct sip_s { - msg_common_t sip_common[1]; // Used with recursive inclusion - msg_pub_t *sip_next; // Ditto - void *sip_user; // Application data - unsigned sip_size; // Size of the structure with - // extension headers - int sip_flags; // Parser flags - - sip_error_t *sip_error; // Erroneous headers - - sip_request_t *sip_request; // Request line - sip_status_t *sip_status; // Status line - - sip_via_t *sip_via; // Via (v) - sip_route_t *sip_route; // Route - sip_record_route_t *sip_record_route; // Record-Route - sip_max_forwards_t *sip_max_forwards; // Max-Forwards - ... -} sip_t; -@endcode - -As you can see above, the public #sip_t structure contains the common -header members that are also found in the beginning of a header -structure. The @e sip_size indicates the size of the structure - the -application can extend the parser and #sip_t structure beyond the -original size. The @e sip_flags contains various flags used during the -parsing and printing process. They are documented in the . These -boilerplate members are followed by the pointers to various message -elements and headers. - -@section msg_parsing_example Result of Parsing Process - -Let us now show how a simple message is parsed and presented to the -applications. As an exampe, we choose a SIP request message with method BYE, -including only the mandatory fields: -@code -BYE sip:joe@example.com SIP/2.0 -Via: SIP/2.0/UDP sip.example.edu;branch=d7f2e89c.74a72681 -Via: SIP/2.0/UDP pc104.example.edu:1030;maddr=110.213.33.19 -From: Bobby Brown ;tag=77241a86 -To: Joe User ;tag=7c6276c1 -Call-ID: 4c4e911b@pc104.example.edu -CSeq: 2 -@endcode - -The figure below shows the layout of the BYE message above after parsing: - -@image html sip-parser2.gif BYE message and its representation in C -@image latex sip-parser2.eps BYE message and its representation in C - -The leftmost box represents the message of type #msg_t. Next box from -the left reprents the #sip_t structure, which contains pointers to a -header objects. The next column contains the header objects. There is -one header object for each message fragment. The rightmost box represents -the I/O buffer used when the message was received. Note that the I/O -buffer may be non-continous and composed of many separate memory areas. - -The message object has link to the public message structure (@a -m_object), to the dual-linked fragment chain (@a m_frags) and to the I/O -buffer (@a m_buffer). The public message structure contains pointers to -the headers according to their type. If there are multiple headers of -the same type (like there are two Via headers in the above message), the -headers are put into a single-linked list. - -Each fragment has pointers to successing and preceding fragment. It also -contains pointer to the corresponding data within the I/O buffer and its -length. - -The main purpose of the fragment chain is to preserve the original order -of the headers. If there were an third Via header after CSeq in the -message, the fragment representing it would be after the CSeq header in -the fragment chain but after second Via in the header list. - -@section msg_parsing_memory Example: Parsing a Complete Message - -The following code fragment is an example of parsing a complete message. The -parsing process is more hairy when there is stream to be parsed. - -@code -msg_t *parse_memory(msg_mclass_t const *mclass, char const data[], int len) -{ - msg_t *msg; - int m; - msg_iovec_t iovec[2] = {{ 0 }}; - - msg = msg_create(mclass, 0); - if (!msg) - return NULL; - - m = msg_recv_iovec(msg, iovec, 2, n, 1); - if (m < 0) { - msg_destroy(msg); - return NULL; - } - assert(m <= 2); - assert(iovec[0].mv_len + iovec[1].mv_len == n); - - memcpy(iovec[0].mv_base, data, n = iovec[0].mv_len); - if (m == 2) - memcpy(iovec[1].mv_base + n, data + n, iovec[1].mv_len); - - msg_recv_commit(msg, iovec[0].mv_len + iovec[1].mv_len, 1); - - m = msg_extract(msg); - assert(m != 0); - if (m < 0) { - msg_destroy(msg); - return NULL; - } - return msg; -} -@endcode - -Let's go through this simple function, step by step. First, we get the @a -data pointer and its size in bytes, @a len. We first initialize an I/O -vector used to represent message with the parser. - -@code -msg_t *parse_memory(msg_mclass_t const *mclass, char const data[], int len) -{ - msg_t *msg; - int m; - msg_iovec_t iovec[2] = {{ 0 }}; -@endcode - -The message class @a mclass (a parser driver object, #msg_mclass_t) is used -to represent a particular protocol-specific parser instance. When a message -object is created, it is given as an argument to msg_create() function: - -@code - msg = msg_create(mclass, 0); - if (!msg) - return NULL; -@endcode - -Next we obtain a memory buffer for data with msg_recv_iovec(). The memory -buffer is usually a single continous memory area, but in some cases it may -consist of two distinct areas. Therefore the @a iovec is used here to pass -the buffers around. The @a iovec is also very handly as it can be directly -passed to various system I/O calls. - -@code - m = msg_recv_iovec(msg, iovec, 2, n, 1); - if (m < 0) { - msg_destroy(msg); - return NULL; - } -@endcode - -These assumptions hold always true when you call msg_recv_iovec() first -time with a complete message: - -@code - assert(m >= 1 && m <= 2); - assert(iovec[0].mv_len + iovec[1].mv_len == n); -@endcode - -Next, we copy the data to the I/O vector and commit the copied data to the -message. Earlier with msg_recv_iovec() we allocated buffer space for data, -now calling msg_recv_commit() indicates that valid data has been copied to -the buffer. The last parameter to msg_recv_commit() indicates that the end -of stream is encountered and no more data is to be expected. - -@code - memcpy(iovec[0].mv_base, data, n = iovec[0].mv_len); - if (m == 2) - memcpy(iovec[1].mv_base + n, data + n, iovec[1].mv_len); - - msg_recv_commit(msg, iovec[0].mv_len + iovec[1].mv_len, 1); -@endcode - -We call msg_extract() next; it takes care of parsing the message. A fatal -parsing error is indicated by returning -1. If the message is incomplete, -msg_extract() returns 0. When a complete message has been parsed, a positive -value is returned. We know that a message cannot be incomplete, as a call to -msg_recv_commit() indicated to the parser that the end-of-stream has been -encountered. - -@code - m = msg_extract(msg); - assert(m != 0); - if (m < 0) { - msg_destroy(msg); - return NULL; - } - return msg; -} -@endcode - - */ - -/**@class msg_s msg.h - * - * @brief Message object. - * - * The message object is used by Sofia parsers for SIP and HTTP - * protocols.

The various SIP headers are also defined in - * . - * - * @section nta_agent_t Creating an NTA Agent - * - * Most of the SIP entities, like @e user @e agent or @e proxy, consist of a - * SIP server and a SIP client working together. The NTA provides a simple - * interface to SIP server and client with the #nta_agent_t objects. - * - * The #nta_agent_t object is created by calling nta_agent_create(). The - * object listens for incoming connections, receives messages, parses them, - * and pass them to the application. It also takes care of resolving the - * domain names and sending the messages. - * - * The agent needs a #su_root_t object to schedule its execution. A root - * object is used to wait for the network events, schedule the timer - * routines, and pass messages asyncronously. A root object can be created - * by, e.g., the function su_root_create(). The root object can be have its - * own thread, or its main loop can be executed by an application thread by - * calling the function su_root_run(). The main loop can be terminated by - * calling the function su_root_break(). - * - * A simple agent could be created as follows: - * @code - * registrar->reg_root = su_root_create(NULL); - * - * if (registrar->reg_root) { - * registrar->reg_agent = nta_agent_create(registrar->reg_root, - * (url_string_t*)argv[1], - * NULL, - * NULL, - * NULL); - * - * if (registrar->reg_agent) { - * su_root_run(registrar->reg_root); - * nta_agent_destroy(registrar->reg_agent); - * } - * - * su_root_destroy(registrar->reg_root); - * } - * @endcode - * - * @section nta_server SIP Server Action - * - * A SIP server responds to the transactions sent by a client. The SIP - * server can operate in two modes; it can be stateless or stateful. This - * section describes how a stateful SIP server uses NTA. - * - * @subsection nta_leg_t The NTA Legs - * - * A leg is required for stateful transaction processing. A default - * leg is created like this: - * @code - * default_leg = nta_leg_tcreate(agent, process_requests, context, - * URLTAG_URL(url), - * NTATAG_NO_DIALOG(1), - * TAG_END()); - * @endcode - * - * The @a url parameter is used to specify which URLs match to the leg. If - * it is given, only requests with requestURI matching are processed by the - * leg. The nta_leg_tcreate() is a @ref tagarg "tagarg" function, taking a - * tagged argument list as its arguments. - * - * Other, ordinary legs can be used to match incoming requests with existing - * dialogs, calls or transaction contexts, or to provide outgoing requests - * with consistent headers. When a call leg is created, it is provided with - * @From and @To headers, and optionally with other headers like - * @CallID, @Route, or @CSeq. - * - * A new call leg can be created as follows: - * @code - * call_leg = nta_leg_tcreate(agent, - * process_call_requests, call_context, - * SIPTAG_CALL_ID(sip->sip_call_id), - * SIPTAG_TO(sip->sip_from), - * SIPTAG_FROM(sip->sip_to), - * TAG_END()); - * @endcode - * - * @note In the example above, the @From and @To are reversed. This - * happens if the headers are taken from an incoming request; the @From - * and @To headers change direction when an outgoing request is initiated. - * - * @note An existing leg can be used in any direction, however. If the leg - * was created for an incoming INVITE transaction, it is also possible to - * use the leg for an outgoing BYE transaction. - * - * @subsection nta_leg_tag Tagging the Call Leg - * - * All the SIP UAS elements are required to tag the @To header in their - * final responses. The function nta_leg_tag() adds a tag to the leg's local - * address. Local address is used as the @To header in the reply messages, - * and as the @From header in the requests. The function nta_incoming_tag() - * adds a tag to a incoming transaction. They are usually used in together, - * using the tag from initial response to the dialog, too: - * e.g., - * @code - * if (!nta_leg_tag(leg, nta_incoming_tag(irq, NULL))) - * nta_incoming_treply(irq, SIP_500_INTERNAL_SERVER_ERROR, TAG_END()); - * @endcode - * - * @subsection nta_incoming_t Incoming Transactions - * - * An incoming transaction object (nta_incoming_t) is created by NTA for - * each unique incoming request message. When NTA has created the incoming - * transaction object, it invokes the callback function provided with - * nta_leg_tcreate(). - * - * The simplest way to reply to the request is to return a valid status code - * from the callback function. Valid status codes are in range of 100 to - * 699, inclusive. If no automatic response is desired, the callback - * function should return 0. - * - * @note If the status code is final, the incoming transaction object will - * be destroyed immediately after the callback function returns. It can not - * be used afterwards. - * - * @note It is not possible to respond with a 2xx status code to an incoming - * INVITE transaction by returning the status code from the callback. - * - * Valid return values for callback function are as follows: - * @li 0, 100 .. 699 for requests other than INVITE, and - * @li 0, 100 .. 199, 300..699 for INVITE requests. - * - * All other return codes are interpreted as 500, that is, a @e 500 @e - * Internal @e Server @e Error reply message is sent back to the client and - * the request is immediately destroyed. - * - * The simple registrar/redirect server may have a incoming request callback - * as follows: - * @code - * int process_request(server_t *server, - * nta_leg_t *leg, - * nta_incoming_t *irq, - * sip_t const *sip) - * { - * sip_contact_t *m; - * - * switch (sip->sip_request->rq_method) { - * case sip_method_register: - * return registrar_add(server, leg, reply, sip); - * - * case sip_method_ack: - * return 500; - * - * case sip_method_cancel: - * return 200; - * - * default: - * if (registrar_find(server, sip->sip_request->rq_url, &m) { - * nta_incoming_treply(irq, SIP_302_MOVED_TEMPORARILY, - * SIPTAG_CONTACT(m), TAG_END()); - * return 302; - * } - * else { - * nta_incoming_treply(irq, SIP_404_NOT_FOUND, TAG_END()); - * return 404; - * } - * } - * } - * @endcode - * - * The default reply message will contain the status line with default - * phrase, then @Via, @To, @From, @CallID, @CSeq, and @ContentLength headers. - * If a more complex response message is required, the application should - * respond using the function nta_incoming_treply(): - * @code - * nta_incoming_treply(reply, SIP_200_OK, - * SIPTAG_CONTACT(contact), - * SIPTAG_CONTENT_TYPE_STR("application/sdp"), - * SIPTAG_PAYLOAD(sdp), - * TAG_END()); - * @endcode - * - * The nta_incoming_treply() is a @ref tagarg "tagarg" function, taking a - * tagged argument list as its argument. - * - * @note It is possible to send provisional replies (containing 1xx status - * codes) several times with nta_incoming_treply(), but only one final - * reply (containing status codes 2xx..6xx) can be sent. However, with - * INVITE requests, a proxy can send a final 2xx reply even after an error - * reply (3xx..6xx). - * - * @section nta_100rel Reliable Provisional Responses - "100rel" - * - * The 100rel SIP extension - * provides reliable provisional responses, provisional responses that are - * retransmitted until a special acknowledgement request, PRACK, is - * received. In addition the PRACK method, the extension defines two - * headers, @RSeq and @RAck, that are used to identify different - * response messages. PRACK method is usable on INVITE requests only. - * - * Using reliable responses is negotiated using the "100rel" option tag. The - * UAC (party sending the INVITE) can include the option tag to the - * @Supported or @Require header. In the first case, the UAC just - * announces support for reliable responses, in the second case, the UAC - * requires that the UAS (party responding to the call) always sends - * provisional responses in reliable manner. - * - * When reliable responses are enabled with NTATAG_REL100() tag, the @b nta - * engine automatically inserts the "100rel" option tag to the @Supported - * header in the INVITE requests. - * - * @subsection nta_reliable_t Responding Reliably - * - * When a UAS wants to respond reliably to a INVITE request, instead of - * familiar nta_incoming_treply() or nta_incoming_mreply() it uses the - * functions nta_reliable_treply() or nta_reliable_mreply(). These functions - * return a pointer to a special object, nta_reliable_t, that is used to - * keep track of unacknowledged responses and respond to the the PRACK - * acknowledgement request. - * - * Both the functions nta_reliable_treply () and nta_reliable_mreply() take - * a callback funtion pointer and an application context pointer as their - * arguments. The callback function is similar to the leg callback function. - * The callback is invoked when a corresponding PRACK request is received, - * or when there is a timeout. - * - * The @b nta takes care of assigning a serial number to each reliable - * response and resending them if no PRACK request is received. It also - * automatically adds the 100rel option tag to the @Require header. - * - * Also, if a request with 100rel in @Require header is responded with usual - * nta_incoming_treply()/nta_incoming_mreply() functions, the @b nta creates - * a reliable response object for each provisional response in behalf of - * application. As the application can not provide a PRACK callback function - * to @b nta, the PRACK requests are not delivered to the application. - * - * @subsection early_dialog UAC Receives a Reliable Response - * - * When a UAC receives a provisional response with a @RSeq header, it is - * required to acknowledge it. In order to do that, it must establish an @e - * early @e dialog with the UAS. In another view, a reliable response is - * used to establish the early dialog. UAC establishes a leg object for the - * early dialog by calling nta_leg_tcreate() with the parameters derived - * from the response message. - * - * @code - * int invite_callback(call_t *call, - * nta_outgoing_t *orq, - * sip_t const *sip) - * { - * int status = sip->sip_status->st_status; - * - * if (!call->has_dialog && - * (status >= 200 || (status > 100 && sip->sip_rseq))) { - * nta_leg_t *early = - * nta_leg_tcreate(call->nta_agent, mid_dialog_request, call, - * SIPTAG_TO(sip->sip_to), - * SIPTAG_FROM(sip->sip_from), - * SIPTAG_CALL_ID(sip->sip_call_id), - * SIPTAG_CSEQ(sip->sip_cseq), - * TAG_END()); - * - * nta_leg_client_route(early, - * sip->sip_record_route, - * sip->sip_contact); - * - * fork = call_fork(call, leg = early); - * - * if (!fork) { - * handle error; - * } - * call = fork; - * } - * @endcode - * - * The original dialog object and client transaction object are used to - * process other call forks. For instance, if the early dialog is - * established with an announcement server it will never lead to an fully - * established call, but an another dialog will be used when the call is - * completed. - * - * @subsection nta_prack Acknowledging Reliable Response - * - * After an early dialog has been established, acknowledging the reliable - * response is trivial. The application can create a PRACK client - * transaction object by calling nta_outgoing_prack() - * - * @section nta_client SIP Client Action - * - * A SIP client initiates the transactions. In some cases, a SIP client is - * also required to invoke additional transactions, like @b ACK or @b - * CANCEL, to finalize the original transaction. This section describes how - * a SIP client uses NTA to make transactions. - * - * @subsection client_nta_leg_t Creating the Call Leg - * - * If the client does not have a suitable call leg, it must create it by - * calling the function nta_leg_tcreate(): - * @code - * context->leg = nta_leg_tcreate(agent, - * callback, context, - * SIPTAG_CALL_ID(call_id), - * SIPTAG_FROM(from), - * SIPTAG_TO(to), - * TAG_END()); - * @endcode - * - * The @p callback function and @p context pointer are used for incoming - * transactions, and they may be @c NULL if no such transactions are - * expected. If the callback is @c NULL, NTA responds to incoming - * transactions with status @e 403 @e Forbidden. - * - * The @a call_id may be @c NULL or left out. In that case, NTA generates a - * new call ID. - * - * The @a from and @a to are used in outgoing transactions. They are also - * used to select which incoming messages belong to this leg. - * - * The initial sequence number can be supplied with SIPTAG_CSEQ() (taking a - * @CSeq structure as parameter). - * - * The additional parameters (after @a to) are included in outgoing messages - * using this leg. Currently, only @c SIPTAG_ROUTE() is supported. - * - * @note Additional tagged parameters are ignored. - * - * @subsection nta_outgoing_t Outgoing requests - * - * The outgoing request is created and sent by nta_outgoing_tcreate(). It - * can be used as follows: - * @code - * oreq = nta_outgoing_tcreate(leg, response_to_register, reg, - * proxy_url, - * SIP_METHOD_REGISTER, - * registrar_url, - * SIPTAG_CONTACT(my_contact), - * TAG_END()); - * @endcode - * - * NTA invokes the callback function response_to_register() each time a - * provisional answer is received, and when a final answer is received. - * - * @note There may be multiple final answers to the INVITE request. - * - * If NTA does not receive answer in timely manner, it will generate a - * @e 408 @e Timeout response and hand that back to the application. - * - * @note After a provisional answer to the INVITE request, no timeout will - * occur inside NTA. Application must itself timeout the INVITE - * transactions if any answer has been received. - * - * The request can be destroyed with NTA function nta_outgoing_destroy(). - * If no final answer has been received, the request is cancelled when it is - * destroyed, too. The application can also cancel the outgoing request by - * calling nta_outgoing_cancel(). - * - * @subsection nta_ack Acknowledging Answers to INVITE - * - * The final answers to the INVITE request must be acknowledged. NTA takes - * care of acknowledging automatically the 3xx..6xx answers; the appliction - * must explicitly create a separate acknowledge transaction to final 2xx - * answers. - * - * The final answer can be acknowledged like this: - * @code - * url = sip->sip_contact ? sip->sip_contact->m_url : original_url; - * ack = nta_outgoing_tcreate(leg, NULL, NULL, - * SIP_METHOD_ACK, - * (url_string_t*)url, - * SIPTAG_CSEQ(sip->sip_cseq), - * SIPTAG_PAYLOAD(sdp), - * TAG_END()); - * @endcode - * - * @note The ACK transaction should be sent to the @Contact specified in the - * 2xx reply. - * - * - * @section nta_stateless_callback Stateless Processing of SIP Messages - * - * When an NTA agent is created, it is possible to provide it with a - * stateless callback function. The callback function will be called when an - * incoming SIP request or response message does not match with an existing - * transaction. - * - * Before invoking the stateless callback the agent will try to match the - * incoming request message with an existing dialog or dialog-less leg (or - * default leg). So, if you have created a default leg, all request messages - * are processed statefully by it instead of being passed to the stateless - * callback function. - * - * If you want to process request messages with stateless callback and still - * use dialog-less legs (for instance, in order to look up domains with - * nta_leg_by_uri()), you have to switch over to @em stateless @em mode by - * including NTATAG_STATELESS(1) in nta_agent_create() or - * nta_agent_set_params() arguments. - * - * Also, if a response message does not match with an existing client - * transaction, the agent will try to use the default outgoing (client) - * transaction. If you have created an default outgoing transaction, all - * stray response messages are passed to it instead of the stateless - * processing function. - * - * @section nta_message_f_example Stateless Callback Function - * - * In addition to the message (@a msg) and its - * parsed contents (@a sip) the callback function gets the - * application-specific context pointer (in this case, @a registrar) and a - * pointer to the NTA agent (@a agent) as its arguments: - * - * @code - * int process_message(nta_agent_context_t *registrar, - * nta_agent_t *agent, - * msg_t *msg, - * sip_t *sip); - * @endcode - * - * The application has three functions that can be used to process the - * messages in stateless manner: - * @li nta_msg_discard() ignores and destroys the message, - * @li nta_msg_tsend() forwards a request or response message, and - * @li nta_msg_treply() replies to a request message in a stateless way. - * - * Additionally, it is possible to process a request message statefully with - * nta_incoming_create(). - * - * The functionality of the stateless callback function can vary greatly, - * depending the purpose of the application. An user-agent, a proxy or a - * registrar/redirect server each have very different callback functions. - * - * A simple redirect server could have a message callback function as - * follows. - * - * @code - * int process_message(redirect_t *r, - * nta_agent_t *agent, - * msg_t *msg, - * sip_t *sip) - * { - * sip_contact_t *m; - * sip_unsupported_t *u; - * - * @endcode - * - * The incoming response messages are simply ignored. The @b ACK requests can - * safely be discarded, too, because the redirect server keeps no state. - * - * @code - * if (!sip->sip_request || sip->sip_request->rq_method == sip_method_ack) { - * nta_msg_discard(agent, msg); - * return 0; - * } - * @endcode - * - * Next, the redirect server first checks if processing the request requires - * a feature that is not supported by it: - * @code - * u = sip_unsupported(msg_home(msg), sip->sip_require, r->r_supported); - * if (u) { - * nta_msg_treply(agent, msg, SIP_420_BAD_EXTENSION, - * SIPTAG_SUPPORTED(r->r_supported), - * SIPTAG_UNSUPPORTED(u), - * TAG_END()); - * return 0; - * } - * @endcode - * - * The @b CANCEL requests terminate a transacton. A stateless redirect - * server does not have transactions, so it redirect replies with a @e 481 - * @e Call @e Leg/Transaction @e Does @e Not @e Exist message: - * @code - * if (sip->sip_request->rq_method == sip_method_cancel) { - * nta_msg_treply(agent, msg, SIP_481_NO_TRANSACTION, TAG_END()); - * return 0; - * } - * @endcode - * - * All other requests are answered normally with a 302 response. - * The location service is - * searched for the request uri, and if a matching address was found, a - * list of active bindings is returned to the client. - * @code - * m = location_find(redirect, sip->sip_request->rq_url); - * if (m) { - * nta_msg_treply(agent, msg, SIP_302_MOVED_TEMPORARILY, - * SIPTAG_CONTACT(m), - * TAG_END()); - * } - * @endcode - * - * Otherwise, @e 404 @e Not @e Found is sent: - * @code - * else { - * nta_msg_treply(agent, msg, SIP_404_NOT_FOUND, TAG_END()); - * } - * - * return 0; - * } - * @endcode - * - */ - -/**@page internal NTA Semantics and Internal Data Flows - * - * NTA implements simple state machines at transaction level.

Its functionality includes call management, -messaging and event retrieval. - -@CONTACT Pekka Pessi - -@STATUS @SofiaSIP Core library - -@LICENSE LGPL - -@par Contributor(s): -- Pekka Pessi -- Pasi Rinne-Rahkola -- Kai Vehmanen -- Martti Mela - -@section nua_overview Overview - -The NUA API gives the high-level application programmer transparent and -full control to the SIP protocol engine below it. NUA provides the call -semantics on top of existing transaction semantics found in -nta module. -With NUA it is possible to create different kind of SIP User Agents, -like terminals, gateways or MCUs. - -The @b nua engine hides many low-level signaling and media management -aspects from the application programmer. It is possible to use different -kind of media interfaces - even remote ones - in a fully transparent way. - -The application and the protocol engine within User Agent library can be run -in separate threads. The protocol engine communicates with the application -using @ref nua_event_e "events", delivered to the application with a a -callback function. The callback function is called within the thread context -of the application, represented with a #su_root_t object. - -@section nua_concepts_user Sofia Concepts for NUA User - -@subsection nua_intro Introduction - -The Sofia software suite is based on certain basic ideas and concepts that -are used in all levels of Sofia software. Many of those are implemented in -Sofia utility library (su) providing -unified interface to the most important OS services and utilities . - -The following sections contain descriptions of the concepts that a user of -NUA library must understand to create a working application. The other -utilities (in the SU library and other libraries of Sofia software suite) -might also be useful for an application developer but one must be careful -when using them because they might change the behavior of the Sofia -software suite in a way that causes NUA library to work incorrectly. -See [su] for more detailed -description of the SU services. - -@subsection nua_root Event loop - root object - -The NUA uses the reactor pattern (also known as dispatcher pattern and -notifier pattern) for event driven systems (see [Using Design Patterns -to Develop Reusable Object-oriented Communication Software, D.C. Schmidt, -CACM October '95, 38(10): 65-74]). Sofia uses a task as basic execution -unit for the programming model. According to the model, the program can -ask that the event loop invokes a callback function when a certain event -occurs. Such events include I/O activity, timers or a asynchronously -delivered messages from other task. - -The root object is a handle representing the task in the application. -Another way of seeing the same thing is that the root object represents -the main event loop of the task. Through the root object the task code -can access its context information (magic) and thread-synchronization -features like wait objects, timers, and messages. - -An application using NUA services must create a root object and the callback -routine to handle @ref nua_event_e "NUA events". The root object is created -with su_root_create() function and the callback routine is registered with -nua_create() function. - -Root object has type #su_root_t. - -See documentation of and for more information -of root object. - -See section #nua_event_e for more information of the callback function. - -@subsection nua_magic Magic - -The magic is a term used for the context pointer that can be bound -to various objects in Sofia stack (for example root object and operation -handle) by the application code. This context pointer is passed back -to the application code when a registered callback function is called by -the main event loop. The Sofia stack retains the context information between -calls to the callback function. An application can use the context information -to store any information it needs for processing the events. - -@subsection nua_memmgmt Memory Handling - -The home-based memory management is useful when a lot of memory blocks are -allocated for given task. The allocations are done via the memory home, -which keeps a reference to each allocated memory block. When the memory -home is then freed, it will free all memory blocks to which it has -reference. This simplifies application logic because application code does -not need to keep track of the allocated memory and free every allocated block -separately. - -An application using NUA services can use the memory management services -provided by the SU library but it is not mandatory. - -See documentation of for more information of memory -management services. - -@subsection nua_tags Tags - -Tagging is the mechanism used in Sofia software for packing parameters to -functions. It enables passing a variable number of parameters having -non-fixed types. For an application programmer the tagging is visible as -macros that are used to encapsulate the passed parameters. When evaluated a -tagging macro creates a structure that contains a tag (telling what is the -type of a parameter) and a value (pointer to opaque data). By checking the -tag the layers of Sofia software check whether they can handle the parameter -or should it just be passed to lower layers for processing. - -There are some tags with special meaning: -- TAG_NULL() (synonymous to TAG_END()) end of tag list -- TAG_SKIP() empty tag item -- TAG_NEXT() tag item pointing to another tag list, ends the current tag list -- TAG_ANY() filter tag accepting any tag -- TAG_IF() conditional inclusion of tag item - -The NUA functions can be called with a list of tagged values if they have -following parameters at the end of parameter list: - -@code -tag_type_t tag, -tag_value_t value, -...); -@endcode - -The last tagged value on the parameter list must be TAG_NULL() -(or TAG_END(), synonym for TAG_NULL()). - -Every tag has two versions: \n -NUTAG_ \n -which takes a value parameter and \n -NUTAG__REF \n -which takes a reference parameter. The latter is used with -tl_gets() function to retrieve tag values from tag list. - -For SIP headers there exists also additional -version of tags: \n -SIPTAG__STR \n -This tag version takes a C-language character string as parameter. -The corresponding tag without _STR suffix takes a parsed value structure -as parameter. - -The following is an example of call to NUA function containing tagged values: -@code -nua_unregister(op->op_handle, - TAG_IF(use_registrar, NUTAG_REGISTRAR(registrar)), - SIPTAG_CONTACT_STR("*"), - SIPTAG_EXPIRES_STR("0"), - TAG_NULL()); -@endcode - -An application using NUA services must use tagged arguments for passing the -parameters to functions. See nua_invite() for discussion on how a SIP -message is constructed from the tags. - -See documentation of for more information of tags and the -module-specific documentation of each Sofia module for information of -tags specific for that module. - -@subsection nua_debugandlogging Debugging and Logging - -The modules of Sofia stack contain configurable debugging and logging -functionality based on the services defined in . The debugging -and logging details (for example level of details on output and output -file name) can be configured by environment variables, directives in -configuration files and compilation directives in the source files. - -Examples of useful directives/ environment variables are: -- #SOFIA_DEBUG Default debug level (0..9) -- #NUA_DEBUG NUA debug level (0..9) -- #NTA_DEBUG Transaction engine debug level (0..9) -- #TPORT_DEBUG Transport event debug level (0..9) -- #TPORT_LOG If set, print out all parsed SIP messages on transport layer -- #TPORT_DUMP Filename for dumping unparsed messages from transport - -The defined debug output levels are: -- 0 fatal errors, panic -- 1 critical errors, minimal progress at subsystem level -- 2 non-critical errors -- 3 warnings, progress messages -- 5 signaling protocol actions (incoming packets, ...) -- 7 media protocol actions (incoming packets, ...) -- 9 entering/exiting functions, very verbatim progress - -An application using NUA services can also use the debugging and -logging services provided by the Sofia stack but it is not mandatory. - -See documentation of for more information of debugging and -logging services. - -@section nua_concepts NUA Concepts - -@subsection nua_stackobject NUA Stack Object - -Stack object represents an instance of SIP stack and media engine. It -contains reference to root object of that stack, user-agent-specific -settings, and reference to the SIP transaction engine, for example. - -A NUA stack object is created by nua_create() function and deleted by -nua_destroy() function. The nua_shutdown() function is used to gracefully -release active the sessions by @b nua engine. - -NUA stack object has type nua_t. - -@subsection nua_operationhandle NUA Operation Handle - -Operation handle represents an abstract SIP call/session. It contains -information of SIP dialog and media session, and state machine that -takes care of the call, high-level SDP offer-answer protocol, registration, -subscriptions, publications and simple SIP transactions. An operation -handle may contain list of tags used when SIP messages are created by -NUA (e.g. From and To headers). - -An operation handle is created explicitly by the application using NUA -for sending messages (function nua_handle()) and by stack for incoming -calls/sessions (starting with INVITE or MESSAGE). The handle is destroyed -by the application using NUA (function nua_handle_destroy()). - -Indication and response events are associated with an operation handle. - -NUA operation handle has type nua_handle_t. - -@subsection nua_stacktread Stack Thread and Message Passing Concepts - -The stack thread is a separate thread from application that provides the -real-time protocol stack operations so that application thread can for -example block or redraw UI as it likes. - -The communication between stack thread and application thread is asynchronous. -Most of the NUA API functions cause a send of a message to the stack thread -for processing and similarly when something happens in the stack thread it -sends a message to the application thread. The messages to the application -thread are delivered as invokes of the application callback function when -the application calls su_root_run() or su_root_step() function. - -@subsection nua_sip_message SIP Message and Header Manipulation - -SIP messages are manipulated with typesafe SIPTAG_ tags. There are -three versions of each SIP tag: -- SIPTAG_() takes a parsed value as parameter. -- SIPTAG__STR() takes an unparsed string as parameter. -- SIPTAG__REF() takes a reference as parameter, is used - with tl_gets() function to retrieve tag values from tag list. -- SIPTAG___STR_REF() takes a reference as parameter, is used - with tl_gets() function to retrieve string tag values from tag list. - -For example a header named "Example" would have tags names SIPTAG_EXAMPLE(), -SIPTAG_EXAMPLE_STR(), and SIPTAG_EXAMPLE_REF(). - -When tags are used in NUA calls the corresponding headers are added to -the message. In case the header can be present only once in a message -and there already exists a value for the header the value given by -tag replaces the existing header value. Passing tag value NULL has no -effect on headers. Passing tag value (void *)-1 removes corresponding -headers from the message. - -For example: - -- sending a SUBSCRIBE with @b Event: header and two @b Accept: headers: - -@code - nua_subscribe(nh, - SIPTAG_EVENT_STR("presence"), - SIPTAG_ACCEPT(accept1), - SIPTAG_ACCEPT(accept2), - TAG_END()); -@endcode - -- fetching tag values when processing nua_r_subscribe event: - -@code - sip_accept_t *ac = NULL; - sip_event_t *o = NULL; - - tl_gets(tl, - SIPTAG_EVENT_REF(o), /* _REF takes a reference! */ - SIPTAG_ACCEPT_REF(ac), - TAG_END()); -@endcode - -@section nua_tutorial SIP/NUA tutorial - -This section describes basic usage scenarios of NUA/Sofia stack using -message sequence charts. - -@subsection nua_outgoingcall Outgoing Call - -@image latex SIP_outgoing_call.eps - -@image html SIP_outgoing_call.gif - - -@subsection nua_incomingcall Incoming Call - -@image latex SIP_incoming_call.eps - -@image html SIP_incoming_call.gif - -@subsection nua_basicoutgoingoperation Basic Outgoing Operation - -@image latex SIP_basic_outgoing_operation.eps - -@image html SIP_basic_outgoing_operation.gif - - -@subsection nua_basicincomingoperation Basic Incoming Operation - -@image latex SIP_basic_incoming_operation.eps - -@image html SIP_basic_incoming_operation.gif - - -@subsection nua_outgoingoperationwithauth Outgoing Operation with Authentication - -@image latex SIP_outgoing_operation_with_auth.eps - -@image html SIP_outgoing_operation_with_auth.gif - -@section nua_simpleapplication Simple Application - -The following sections will present code examples from a simple application -that uses services of NUA.

C1 init nua_invite() INVITE calling Generate offer - Client application starts call be invoking nua_invite(). By default, stack runs - the initial offer/answer step and sends @b INVITE request with the SDP - offer. -
C2calling18X-proceeding(Save answer) - Stack receives a 18X response (a provisional response between 101 - and 199). It establishes an early dialog with server. If the provisional - response contains an SDP answer, a session with early media is - established. The caller can be listen to, for instance, ring tone or - announcements about call progress using the early media session. -
C3acalling2XX-completingSave answer - Client receives a 2XX response (usually 200 OK) indicating that - call has been accepted by the server. If there is an SDP session - description included with response, it is stored. - - Unless the @ref NUTAG_AUTOACK() "auto-ack" mode is explicitly turned off - by application the client does not stay in @b completing state, but - proceeds immediately to next state transition. -

C6bproceeding
C7acallingnua_cancel()CANCELcalling- - Client can ask server to cancel the call attempt while in @b calling or - @b proceeding state. There is no direct call state transition caused by - nua_cancel(). The call state changes when the server returns a response. - After receiving a CANCEL request the server will usually return a 487 - Request Terminated response and call is terminated as in previous - item. - - However, there is a race condition and the server can respond with a - succesful 2XX response before receiving CANCEL. In that case, the call is - established as usual. It is up to application to terminate the call with - nua_bye(). -
C7bproceedingproceeding
C8aproceedingnua_bye()CANCELterminating*- - The call cannot be terminated with BYE before the dialog is established - with a non-100 preliminary response. So, instead of a @b BYE, stack sends - a @b CANCEL request, and enters terminating state. - - However, there is a race condition and the server can respond with a - succesful 2XX response before receiving CANCEL. If the server responds with - a 2XX response, the nua will automatically send a BYE request asking server - to terminate the call. -
C8bproceedingnua_bye()BYE - Even an early session can be terminated after entering @b proceeding - state with nua_bye(). Stack sends a @b BYE request, and enters - terminating state. Unlike @b CANCEL, @b BYE affects only one fork. - - However, there is a race condition and the server can respond with a - succesful 2XX response before receiving BYE.

The diplay name is taken from NUTAG_M_DISPLAY(), URL username - * part is taken from NUTAG_M_USERNAME(), URI parameters from - * NUTAG_M_PARAMS(), and Contact header parameters from NUTAG_M_FEATURES(). - * If NUTAG_CALLEE_CAPS(1) is specified, additional Contact header - * parameters are generated based on SDP capabilities and SIP @Allow header. - * - * Note that @b nua may append a identifier of its own to the @Contact URI - * username. Such nua-generated identifier trailer always starts with "=" - * (equal sign), rest of the nua-generated identifier may contain any - * url-unreserved characters except "=". - * - * Likewise, nua may add transport parameters (such as "transport=tcp" or - * "maddr") to the @Contact URI. It can add addtional header parameters, like - * "+sip.instance" or "reg-id", too. - * - * For instance, if application uses tags like - * @code - * nua_register(nh, - * NUTAG_M_DISPLAY("1"), - * NUTAG_M_USERNAME("line-1"), - * NUTAG_M_PARAMS("user=phone"), - * NUTAG_M_FEATURES("audio"), - * NUTAG_CALLEE_CAPS(0), - * TAG_END()) - * @endcode - * @b nua can generate a Contact header like - * @code - * Contact: 1 - * ;audio;reg-id=1 - * ;+sip.instance=urn:uuid:97701ad9-39df-1229-1083-dbc0a85f029c - * @endcode - * - * The incoming request from the proxy should contain the registered contact - * URI as the request URI. The application can use the username prefix set - * by NUTAG_M_USERNAME() and the non-transport parameters of the request URI - * set by NUTAG_M_PARAMS() when determining to which registration the - * incoming request belongs. - * - * For example, a request line correspoding to the @Contact in above example - * may look like: - * @code - * INVITE sip:line-1=SSQAIbjv@192.168.1.200;user=phone SIP/2.0 - * @endcode - * - * @sa NUTAG_M_DISPLAY(), NUTAG_M_USERNAME(), NUTAG_M_PARAMS(), - * NUTAG_M_FEATURES(), NUTAG_CALLEE_CAPS(). - * - * @par NAT, Firewall and Outbound Support - * - * Normally, @b nua will start start a protocol engine for outbound - * connections used for NAT and firewall traversal and connectivity checks - * when registering. - * - * @note If the application provides @b nua with a - * @Contact header of its own (or includes a SIPTAG_CONTACT(NULL) tag in - * nua_register() tags), the outbound protocol engine is not started. It is - * assumed that the application knows better what it is doing when it sets - * the @Contact, or it is using experimental CPL upload as specified in - * - * draft-lennox-sip-reg-payload-01.txt. - * - * First, outbound engine will probe for NATs in between UA and registrar. - * It will send a REGISTER request as usual. Upon receiving the response it - * checks for the presence of "received" and "rport" parameters in the Via - * header returned by registrar. The presence of NAT is determined from the - * "received" parameter in a Via header. When a REGISTER request was sent, - * the stack inserted the actual source IP address in the Via header: if - * that is different from the source IP address seen by the registrar, the - * registrar inserts the source IP address it sees into the "received" - * parameter. - * - * Please note that an ALG (application-level gateway) modifying the Via - * headers in outbound requests and again in incoming responses will make - * the above-described NAT check to fail. - * - * The response to the initial REGISTER should also include option tags - * indicating whether registrar supports various SIP extension options: @e - * outbound, @e pref, @e path, @e gruu. - * - * Basically, @e outbound means that instead of registering its contact URI - * with a particular address-of-record URI, the user-agent registers a - * transport-level connection. Such a connection is identified on the - * Contact header field with an instance identifier, application-provided - * @ref NUTAG_INSTANCE() "unique string" identifying the user-agent instance - * and a stack-generated numeric index identifying the transport-level - * connection. - * - * If the @e outbound extension is supported, NUTAG_OUTBOUND() contains - * option string "outbound" and the application has provided an instance - * identifer to the stack with NUTAG_INSTANCE(), the nua_register() will try - * to use outbound. - * - * If @e outbound is not supported, nua_register() has to generate a URI - * that can be used to reach it from outside. It will check for public - * transport addresses detected by underlying stack with, e.g., STUN, UPnP - * or SOCKS. If there are public addresses, nua_register() will use them. If - * there is no public address, it will try to generate a Contact URI from - * the "received" and "rport" parameters found in the Via header of the - * response message. - * - * @todo Actually generate public addresses. - * - * You can disable this kind of NAT traversal by setting "no-natify" into - * NUTAG_OUTBOUND() options string. - * - * @par GRUU and Service-Route - * - * After a successful response to the REGISTER request has been received, - * nua_register() will update the information about the registration based - * on it. If there is a "gruu" parameter included in the response, - * nua_register() will save it and use the gruu URI in the Contact header - * fields of dialog-establishing messages, such as INVITE or SUBSCRIBE. - * Also, if the registrar has included a Service-Route header in the - * response, and the service route feature has not been disabled using - * NUTAG_SERVICE_ROUTE_ENABLE(), the route URIs from the Service-Route - * header will be used for initial non-REGISTER requests. - * - * The #nua_r_register message will include the contact header and route - * used in with the registration. - * - * @par Registration Keep-Alive - * - * After the registration has successfully completed the nua_register() will - * validate the registration and initiate the keepalive mechanism, too. The - * user-agent validates the registration by sending a OPTIONS requests to - * itself. If there is an error, nua_register() will indicate that to the - * application using #nua_i_outbound event, and start unregistration - * procedure (unless that has been explicitly disabled). - * - * You can disable validation by inserting "no-validate" into - * NUTAG_OUTBOUND() string. - * - * The keepalive mechanism depends on the network features detected earlier. - * If @a outbound extension is used, the STUN keepalives will be used. - * Otherwise, NUA stack will repeatedly send OPTIONS requests to itself. In - * order to save bandwidth, it will include Max-Forwards: 0 in the - * keep-alive requests, however. The keepalive interval is determined by - * NUTAG_KEEPALIVE() parameter. If the interval is 0, no keepalive messages - * is sent. - * - * You can disable keepalive OPTIONS by inserting "no-options-keepalive" - * into NUTAG_OUTBOUND() string. Currently there are no other keepalive - * mechanisms available. - * - * The value of NUTAG_KEEPALIVE_STREAM(), if specified, is used to indicate - * the desired transport-layer keepalive interval for stream-based - * transports like TLS and TCP. - * - * As alternative to OPTIONS/STUN keepalives, the client can propose - * a more frequent registration refresh interval with - * NUTAG_M_FEATURES() (e.g. NUTAG_M_FEATURES("expires=120") given as - * parameter to nua_register()). - * - * @sa #nua_r_register, nua_unregister(), #nua_r_unregister, - * #nua_i_register, - * @RFC3261 section 10, - * @Expires, @Contact, @CallID, @CSeq, - * @Path, @RFC3327, @ServiceRoute, @RFC3608, @RFC3680, - * NUTAG_REGISTRAR(), NUTAG_INSTANCE(), NUTAG_OUTBOUND(), - * NUTAG_KEEPALIVE(), NUTAG_KEEPALIVE_STREAM(), - * SIPTAG_CONTACT(), SIPTAG_CONTACT_STR(), NUTAG_M_USERNAME(), - * NUTAG_M_DISPLAY(), NUTAG_M_PARAMS(), NUTAG_M_FEATURES(), - */ - -/** @NUA_EVENT nua_r_register - * - * Response to an outgoing REGISTER. - * - * The REGISTER may be sent explicitly by nua_register() or implicitly by - * NUA state machines. - * - * When REGISTER request has been restarted the @a status may be 100 even - * while the real response status returned is different. - * - * @param status response status code - * (if the request is retried, @a status is 100, the @a - * sip->sip_status->st_status contain the real status code - * from the response message, e.g., 302, 401, or 407) - * @param phrase a short textual description of @a status code - * @param nh operation handle associated with the registration - * @param hmagic application context associated with the registration - * @param sip response message to REGISTER request or NULL upon an error - * (status code is in @a status and - * descriptive message in @a phrase parameters) - * @param tags empty - * - * @sa nua_register(), nua_unregister(), #nua_r_unregister, - * @Contact, @CallID, @CSeq, @RFC3261 section 10, - * @Path, @RFC3327, @ServiceRoute, @RFC3608, @RFC3680 - * - * @END_NUA_EVENT - */ - -/**@fn void nua_unregister(nua_handle_t *nh, tag_type_t tag, tag_value_t value, ...); - * Unregister. - * - * Send a REGISTER request with expiration time 0.

If neither is given, the complete request line - * already specified using SIPTAG_REQUEST() or SIPTAG_REQUEST_STR() is used. - * If none of the tags above are given, an internal error is returned to the - * application. At this point, the target URI is stored in the request line, - * together with method name ("INVITE") and protocol version ("SIP/2.0"). - * The initial dialog information is also created: @CallID, @CSeq headers - * are generated, if they do not exist, and an unique tag is added to @From - * header. - * - * @par - * For the initial INVITE requests, the @Route headers specified by - * SIPTAG_ROUTE()/SIPTAG_ROUTER_STR() tags in nua_handle() and nua_invite() - * calls are inserted to the request. Next the initial route set specified - * by NUTAG_INITIAL_ROUTE()/NUTAG_INITIAL_ROUTE_STR() tags is prepended to - * the route.

If @soa is not disabled with NUTAG_MEDIA_ENABLE(0), the - * SDP should be included in the SOATAG_USER_SDP() or SOATAG_USER_SDP_STR() - * parameter given to nua_respond(). If it is disabled, the SDP should be - * included in the response message using SIPTAG_PAYLOAD() or - * SIPTAG_PAYLOAD_STR().

Introduction - - On the Internet multicast backbone (Mbone), a session directory tool - is used to advertise multimedia conferences and communicate the - conference addresses and conference tool-specific information - necessary for participation. This document defines a session - description protocol for this purpose, and for general real-time - multimedia session description purposes. This memo does not describe - multicast address allocation or the distribution of SDP messages in - detail. These are described in accompanying memos. SDP is not - intended for negotiation of media encodings. - - - - - - - - -Handley & Jacobson Standards Track [Page 1] - -RFC 2327 SDP April 1998 - - -2. Background - - The Mbone is the part of the internet that supports IP multicast, and - thus permits efficient many-to-many communication. It is used - extensively for multimedia conferencing. Such conferences usually - have the property that tight coordination of conference membership is - not necessary; to receive a conference, a user at an Mbone site only - has to know the conference's multicast group address and the UDP - ports for the conference data streams. - - Session directories assist the advertisement of conference sessions - and communicate the relevant conference setup information to - prospective participants. SDP is designed to convey such information - to recipients. SDP is purely a format for session description - it - does not incorporate a transport protocol, and is intended to use - different transport protocols as appropriate including the Session - Announcement Protocol [4], Session Initiation Protocol [11], Real- - Time Streaming Protocol [12], electronic mail using the MIME - extensions, and the Hypertext Transport Protocol. - - SDP is intended to be general purpose so that it can be used for a - wider range of network environments and applications than just - multicast session directories. However, it is not intended to - support negotiation of session content or media encodings - this is - viewed as outside the scope of session description. - -3. Glossary of Terms - - The following terms are used in this document, and have specific - meaning within the context of this document. - - Conference - A multimedia conference is a set of two or more communicating users - along with the software they are using to communicate. - - Session - A multimedia session is a set of multimedia senders and receivers - and the data streams flowing from senders to receivers. A - multimedia conference is an example of a multimedia session. - - Session Advertisement - See session announcement. - - Session Announcement - A session announcement is a mechanism by which a session - description is conveyed to users in a proactive fashion, i.e., the - session description was not explicitly requested by the user. - - - - -Handley & Jacobson Standards Track [Page 2] - -RFC 2327 SDP April 1998 - - - Session Description - A well defined format for conveying sufficient information to - discover and participate in a multimedia session. - -3.1. Terminology - - The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", - "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this - document are to be interpreted as described in RFC 2119. - -4. SDP Usage - -4.1. Multicast Announcements - - SDP is a session description protocol for multimedia sessions. A - common mode of usage is for a client to announce a conference session - by periodically multicasting an announcement packet to a well known - multicast address and port using the Session Announcement Protocol - (SAP). - - SAP packets are UDP packets with the following format: - - |--------------------| - | SAP header | - |--------------------| - | text payload | - |////////// - - - The header is the Session Announcement Protocol header. SAP is - described in more detail in a companion memo [4] - - The text payload is an SDP session description, as described in this - memo. The text payload should be no greater than 1 Kbyte in length. - If announced by SAP, only one session announcement is permitted in a - single packet. - -4.2. Email and WWW Announcements - - Alternative means of conveying session descriptions include - electronic mail and the World Wide Web. For both email and WWW - distribution, the use of the MIME content type "application/sdp" - should be used. This enables the automatic launching of applications - for participation in the session from the WWW client or mail reader - in a standard manner. - - - - - - -Handley & Jacobson Standards Track [Page 3] - -RFC 2327 SDP April 1998 - - - Note that announcements of multicast sessions made only via email or - the World Wide Web (WWW) do not have the property that the receiver - of a session announcement can necessarily receive the session because - the multicast sessions may be restricted in scope, and access to the - WWW server or reception of email is possible outside this scope. SAP - announcements do not suffer from this mismatch. - -5. Requirements and Recommendations - - The purpose of SDP is to convey information about media streams in - multimedia sessions to allow the recipients of a session description - to participate in the session. SDP is primarily intended for use in - an internetwork, although it is sufficiently general that it can - describe conferences in other network environments. - - A multimedia session, for these purposes, is defined as a set of - media streams that exist for some duration of time. Media streams - can be many-to-many. The times during which the session is active - need not be continuous. - - Thus far, multicast based sessions on the Internet have differed from - many other forms of conferencing in that anyone receiving the traffic - can join the session (unless the session traffic is encrypted). In - such an environment, SDP serves two primary purposes. It is a means - to communicate the existence of a session, and is a means to convey - sufficient information to enable joining and participating in the - session. In a unicast environment, only the latter purpose is likely - to be relevant. - - Thus SDP includes: - - o Session name and purpose - - o Time(s) the session is active - - o The media comprising the session - - o Information to receive those media (addresses, ports, formats and - so on) - - As resources necessary to participate in a session may be limited, - some additional information may also be desirable: - - o Information about the bandwidth to be used by the conference - - o Contact information for the person responsible for the session - - - - - -Handley & Jacobson Standards Track [Page 4] - -RFC 2327 SDP April 1998 - - - In general, SDP must convey sufficient information to be able to join - a session (with the possible exception of encryption keys) and to - announce the resources to be used to non-participants that may need - to know. - -5.1. Media Information - - SDP includes: - - o The type of media (video, audio, etc) - - o The transport protocol (RTP/UDP/IP, H.320, etc) - - o The format of the media (H.261 video, MPEG video, etc) - - For an IP multicast session, the following are also conveyed: - - o Multicast address for media - - o Transport Port for media - - This address and port are the destination address and destination - port of the multicast stream, whether being sent, received, or both. - - For an IP unicast session, the following are conveyed: - - o Remote address for media - - o Transport port for contact address - - The semantics of this address and port depend on the media and - transport protocol defined. By default, this is the remote address - and remote port to which data is sent, and the remote address and - local port on which to receive data. However, some media may define - to use these to establish a control channel for the actual media - flow. - -5.2. Timing Information - - Sessions may either be bounded or unbounded in time. Whether or not - they are bounded, they may be only active at specific times. - - SDP can convey: - - o An arbitrary list of start and stop times bounding the session - - o For each bound, repeat times such as "every Wednesday at 10am for - one hour" - - - -Handley & Jacobson Standards Track [Page 5] - -RFC 2327 SDP April 1998 - - - This timing information is globally consistent, irrespective of local - time zone or daylight saving time. - -5.3. Private Sessions - - It is possible to create both public sessions and private sessions. - Private sessions will typically be conveyed by encrypting the session - description to distribute it. The details of how encryption is - performed are dependent on the mechanism used to convey SDP - see [4] - for how this is done for session announcements. - - If a session announcement is private it is possible to use that - private announcement to convey encryption keys necessary to decode - each of the media in a conference, including enough information to - know which encryption scheme is used for each media. - -5.4. Obtaining Further Information about a Session - - A session description should convey enough information to decide - whether or not to participate in a session. SDP may include - additional pointers in the form of Universal Resources Identifiers - (URIs) for more information about the session. - -5.5. Categorisation - - When many session descriptions are being distributed by SAP or any - other advertisement mechanism, it may be desirable to filter - announcements that are of interest from those that are not. SDP - supports a categorisation mechanism for sessions that is capable of - being automated. - -5.6. Internationalization - - The SDP specification recommends the use of the ISO 10646 character - sets in the UTF-8 encoding (RFC 2044) to allow many different - languages to be represented. However, to assist in compact - representations, SDP also allows other character sets such as ISO - 8859-1 to be used when desired. Internationalization only applies to - free-text fields (session name and background information), and not - to SDP as a whole. - -6. SDP Specification - - SDP session descriptions are entirely textual using the ISO 10646 - character set in UTF-8 encoding. SDP field names and attributes names - use only the US-ASCII subset of UTF-8, but textual fields and - attribute values may use the full ISO 10646 character set. The - textual form, as opposed to a binary encoding such as ASN/1 or XDR, - - - -Handley & Jacobson Standards Track [Page 6] - -RFC 2327 SDP April 1998 - - - was chosen to enhance portability, to enable a variety of transports - to be used (e.g, session description in a MIME email message) and to - allow flexible, text-based toolkits (e.g., Tcl/Tk ) to be used to - generate and to process session descriptions. However, since the - total bandwidth allocated to all SAP announcements is strictly - limited, the encoding is deliberately compact. Also, since - announcements may be transported via very unreliable means (e.g., - email) or damaged by an intermediate caching server, the encoding was - designed with strict order and formatting rules so that most errors - would result in malformed announcements which could be detected - easily and discarded. This also allows rapid discarding of encrypted - announcements for which a receiver does not have the correct key. - - An SDP session description consists of a number of lines of text of - the form = is always exactly one character and is - case-significant. is a structured text string whose format - depends on . It also will be case-significant unless a - specific field defines otherwise. Whitespace is not permitted either - side of the `=' sign. In general is either a number of fields - delimited by a single space character or a free format string. - - A session description consists of a session-level description - (details that apply to the whole session and all media streams) and - optionally several media-level descriptions (details that apply onto - to a single media stream). - - An announcement consists of a session-level section followed by zero - or more media-level sections. The session-level part starts with a - `v=' line and continues to the first media-level section. The media - description starts with an `m=' line and continues to the next media - description or end of the whole session description. In general, - session-level values are the default for all media unless overridden - by an equivalent media-level value. - - When SDP is conveyed by SAP, only one session description is allowed - per packet. When SDP is conveyed by other means, many SDP session - descriptions may be concatenated together (the `v=' line indicating - the start of a session description terminates the previous - description). Some lines in each description are required and some - are optional but all must appear in exactly the order given here (the - fixed order greatly enhances error detection and allows for a simple - parser). Optional items are marked with a `*'. - -Session description - v= (protocol version) - o= (owner/creator and session identifier). - s= (session name) - i=* (session information) - - - -Handley & Jacobson Standards Track [Page 7] - -RFC 2327 SDP April 1998 - - - u=* (URI of description) - e=* (email address) - p=* (phone number) - c=* (connection information - not required if included in all media) - b=* (bandwidth information) - One or more time descriptions (see below) - z=* (time zone adjustments) - k=* (encryption key) - a=* (zero or more session attribute lines) - Zero or more media descriptions (see below) - -Time description - t= (time the session is active) - r=* (zero or more repeat times) - -Media description - m= (media name and transport address) - i=* (media title) - c=* (connection information - optional if included at session-level) - b=* (bandwidth information) - k=* (encryption key) - a=* (zero or more media attribute lines) - - The set of `type' letters is deliberately small and not intended to - be extensible -- SDP parsers must completely ignore any announcement - that contains a `type' letter that it does not understand. The - `attribute' mechanism ("a=" described below) is the primary means for - extending SDP and tailoring it to particular applications or media. - Some attributes (the ones listed in this document) have a defined - meaning but others may be added on an application-, media- or - session-specific basis. A session directory must ignore any - attribute it doesn't understand. - - The connection (`c=') and attribute (`a=') information in the - session-level section applies to all the media of that session unless - overridden by connection information or an attribute of the same name - in the media description.

is the globally - unique address of the machine from which the session was created. - For an address type of IP4, this is either the fully-qualified domain - name of the machine, or the dotted-decimal representation of the IP - version 4 address of the machine. For an address type of IP6, this - is either the fully-qualified domain name of the machine, or the - compressed textual representation of the IP version 6 address of the - machine. For both IP4 and IP6, the fully-qualified domain name is - the form that SHOULD be given unless this is unavailable, in which - case the globally unique address may be substituted. A local IP - address MUST NOT be used in any context where the SDP description - might leave the scope in which the address is meaningful. - - In general, the "o=" field serves as a globally unique identifier for - this version of this session description, and the subfields excepting - the version taken together identify the session irrespective of any - modifications. - - Session Name - - s= - - The "s=" field is the session name. There must be one and only one - "s=" field per session description, and it must contain ISO 10646 - characters (but see also the `charset' attribute below). - - Session and Media Information - - i= - - The "i=" field is information about the session. There may be at - most one session-level "i=" field per session description, and at - most one "i=" field per media. Although it may be omitted, this is - discouraged for session announcements, and user interfaces for - composing sessions should require text to be entered. If it is - present it must contain ISO 10646 characters (but see also the - `charset' attribute below). - - A single "i=" field can also be used for each media definition. In - media definitions, "i=" fields are primarily intended for labeling - media streams. As such, they are most likely to be useful when a - - - -Handley & Jacobson Standards Track [Page 10] - -RFC 2327 SDP April 1998 - - - single session has more than one distinct media stream of the same - media type.

For example, - - e=Mark Handley - - The free text string should be in the ISO-10646 character set with - UTF-8 encoding, or alternatively in ISO-8859-1 or other encodings - if the appropriate charset session-level attribute is set. - - Connection Data - - c=
- - The "c=" field contains connection data. - - A session announcement must contain one "c=" field in each media - description (see below) or a "c=" field at the session-level. It may - contain a session-level "c=" field and one additional "c=" field per - media description, in which case the per-media values override the - session-level settings for the relevant media. - - The first sub-field is the network type, which is a text string - giving the type of network. Initially "IN" is defined to have the - meaning "Internet". - - The second sub-field is the address type. This allows SDP to be used - for sessions that are not IP based. Currently only IP4 is defined. - - The third sub-field is the connection address. Optional extra - subfields may be added after the connection address depending on the - value of the
field. - - For IP4 addresses, the connection address is defined as follows: - - o Typically the connection address will be a class-D IP multicast - - group address. If the session is not multicast, then the - connection address contains the fully-qualified domain name or the - unicast IP address of the expected data source or data relay or - data sink as determined by additional attribute fields. It is not - expected that fully-qualified domain names or unicast addresses - - - -Handley & Jacobson Standards Track [Page 12] - -RFC 2327 SDP April 1998 - - - will be given in a session description that is communicated by a - multicast announcement, though this is not prohibited. If a - unicast data stream is to pass through a network address - translator, the use of a fully-qualified domain name rather than an - unicast IP address is RECOMMENDED. In other cases, the use of an - IP address to specify a particular interface on a multi-homed host - might be required. Thus this specification leaves the decision as - to which to use up to the individual application, but all - applications MUST be able to cope with receiving both formats. - - o Conferences using an IP multicast connection address must also have - a time to live (TTL) value present in addition to the multicast - address. The TTL and the address together define the scope with - which multicast packets sent in this conference will be sent. TTL - values must be in the range 0-255. - - The TTL for the session is appended to the address using a slash as - a separator. An example is: - - c=IN IP4 224.2.1.1/127 - - Hierarchical or layered encoding schemes are data streams where the - encoding from a single media source is split into a number of - layers. The receiver can choose the desired quality (and hence - bandwidth) by only subscribing to a subset of these layers. Such - layered encodings are normally transmitted in multiple multicast - groups to allow multicast pruning. This technique keeps unwanted - traffic from sites only requiring certain levels of the hierarchy. - For applications requiring multiple multicast groups, we allow the - following notation to be used for the connection address: - - // - - If the number of addresses is not given it is assumed to be one. - Multicast addresses so assigned are contiguously allocated above - the base address, so that, for example: - - c=IN IP4 224.2.1.1/127/3 - - would state that addresses 224.2.1.1, 224.2.1.2 and 224.2.1.3 are - to be used at a ttl of 127. This is semantically identical to - including multiple "c=" lines in a media description: - - c=IN IP4 224.2.1.1/127 - c=IN IP4 224.2.1.2/127 - c=IN IP4 224.2.1.3/127 - - - - - -Handley & Jacobson Standards Track [Page 13] - -RFC 2327 SDP April 1998 - - - Multiple addresses or "c=" lines can only be specified on a per- - media basis, and not for a session-level "c=" field. - - It is illegal for the slash notation described above to be used for - IP unicast addresses. - - Bandwidth - - b=: - - o This specifies the proposed bandwidth to be used by the session or - media, and is optional. - - o is in kilobits per second - - o is a single alphanumeric word giving the meaning of the - bandwidth figure. - - o Two modifiers are initially defined: - - CT Conference Total: An implicit maximum bandwidth is associated with - each TTL on the Mbone or within a particular multicast - administrative scope region (the Mbone bandwidth vs. TTL limits are - given in the MBone FAQ). If the bandwidth of a session or media in - a session is different from the bandwidth implicit from the scope, - a `b=CT:...' line should be supplied for the session giving the - proposed upper limit to the bandwidth used. The primary purpose of - this is to give an approximate idea as to whether two or more - conferences can co-exist simultaneously. - - AS Application-Specific Maximum: The bandwidth is interpreted to be - application-specific, i.e., will be the application's concept of - maximum bandwidth. Normally this will coincide with what is set on - the application's "maximum bandwidth" control if applicable. - - Note that CT gives a total bandwidth figure for all the media at - all sites. AS gives a bandwidth figure for a single media at a - single site, although there may be many sites sending - simultaneously. - - o Extension Mechanism: Tool writers can define experimental bandwidth - modifiers by prefixing their modifier with "X-". For example: - - b=X-YZ:128 - - SDP parsers should ignore bandwidth fields with unknown modifiers. - Modifiers should be alpha-numeric and, although no length limit is - given, they are recommended to be short. - - - -Handley & Jacobson Standards Track [Page 14] - -RFC 2327 SDP April 1998 - - - Times, Repeat Times and Time Zones - - t= - - o "t=" fields specify the start and stop times for a conference - session. Multiple "t=" fields may be used if a session is active - at multiple irregularly spaced times; each additional "t=" field - specifies an additional period of time for which the session will - be active. If the session is active at regular times, an "r=" - field (see below) should be used in addition to and following a - "t=" field - in which case the "t=" field specifies the start and - stop times of the repeat sequence. - - o The first and second sub-fields give the start and stop times for - the conference respectively. These values are the decimal - representation of Network Time Protocol (NTP) time values in - seconds [1]. To convert these values to UNIX time, subtract - decimal 2208988800. - - o If the stop-time is set to zero, then the session is not bounded, - though it will not become active until after the start-time. If - the start-time is also zero, the session is regarded as permanent. - - User interfaces should strongly discourage the creation of - unbounded and permanent sessions as they give no information about - when the session is actually going to terminate, and so make - scheduling difficult. - - The general assumption may be made, when displaying unbounded - sessions that have not timed out to the user, that an unbounded - session will only be active until half an hour from the current - time or the session start time, whichever is the later. If - behaviour other than this is required, an end-time should be given - and modified as appropriate when new information becomes available - about when the session should really end. - - Permanent sessions may be shown to the user as never being active - unless there are associated repeat times which state precisely when - the session will be active. In general, permanent sessions should - not be created for any session expected to have a duration of less - than 2 months, and should be discouraged for sessions expected to - have a duration of less than 6 months. - - r= - - o "r=" fields specify repeat times for a session. For example, if - a session is active at 10am on Monday and 11am on Tuesday for one - - - -Handley & Jacobson Standards Track [Page 15] - -RFC 2327 SDP April 1998 - - - hour each week for three months, then the in the - corresponding "t=" field would be the NTP representation of 10am on - the first Monday, the would be 1 week, the - would be 1 hour, and the offsets would be zero - and 25 hours. The corresponding "t=" field stop time would be the - NTP representation of the end of the last session three months - later. By default all fields are in seconds, so the "r=" and "t=" - fields might be: - - t=3034423619 3042462419 - r=604800 3600 0 90000 - - To make announcements more compact, times may also be given in units - of days, hours or minutes. The syntax for these is a number - immediately followed by a single case-sensitive character. - Fractional units are not allowed - a smaller unit should be used - instead. The following unit specification characters are allowed: - - d - days (86400 seconds) - h - minutes (3600 seconds) - m - minutes (60 seconds) - s - seconds (allowed for completeness but not recommended) - - Thus, the above announcement could also have been written: - - r=7d 1h 0 25h - - Monthly and yearly repeats cannot currently be directly specified - with a single SDP repeat time - instead separate "t" fields should - be used to explicitly list the session times. - - z= .... - - o To schedule a repeated session which spans a change from daylight- - saving time to standard time or vice-versa, it is necessary to - specify offsets from the base repeat times. This is required - because different time zones change time at different times of day, - different countries change to or from daylight time on different - dates, and some countries do not have daylight saving time at all. - - Thus in order to schedule a session that is at the same time winter - and summer, it must be possible to specify unambiguously by whose - time zone a session is scheduled. To simplify this task for - receivers, we allow the sender to specify the NTP time that a time - zone adjustment happens and the offset from the time when the - session was first scheduled. The "z" field allows the sender to - specify a list of these adjustment times and offsets from the base - time. - - - -Handley & Jacobson Standards Track [Page 16] - -RFC 2327 SDP April 1998 - - - An example might be: - - z=2882844526 -1h 2898848070 0 - - This specifies that at time 2882844526 the time base by which the - session's repeat times are calculated is shifted back by 1 hour, - and that at time 2898848070 the session's original time base is - restored. Adjustments are always relative to the specified start - time - they are not cumulative. - - o If a session is likely to last several years, it is expected - that - the session announcement will be modified periodically rather than - transmit several years worth of adjustments in one announcement. - - Encryption Keys - - k= - k=: - - o The session description protocol may be used to convey encryption - keys. A key field is permitted before the first media entry (in - which case it applies to all media in the session), or for each - media entry as required. - - o The format of keys and their usage is outside the scope of this - document, but see [3]. - - o The method indicates the mechanism to be used to obtain a usable - key by external means, or from the encoded encryption key given. - - The following methods are defined: - - k=clear: - The encryption key (as described in [3] for RTP media streams - under the AV profile) is included untransformed in this key - field. - - k=base64: - The encryption key (as described in [3] for RTP media streams - under the AV profile) is included in this key field but has been - base64 encoded because it includes characters that are - prohibited in SDP. - - k=uri: - A Universal Resource Identifier as used by WWW clients is - included in this key field. The URI refers to the data - containing the key, and may require additional authentication - - - -Handley & Jacobson Standards Track [Page 17] - -RFC 2327 SDP April 1998 - - - before the key can be returned. When a request is made to the - given URI, the MIME content-type of the reply specifies the - encoding for the key in the reply. The key should not be - obtained until the user wishes to join the session to reduce - synchronisation of requests to the WWW server(s). - - k=prompt - No key is included in this SDP description, but the session or - media stream referred to by this key field is encrypted. The - user should be prompted for the key when attempting to join the - session, and this user-supplied key should then be used to - decrypt the media streams. - - Attributes - - a= - a=: - - Attributes are the primary means for extending SDP. Attributes may - be defined to be used as "session-level" attributes, "media-level" - attributes, or both. - - A media description may have any number of attributes ("a=" fields) - which are media specific. These are referred to as "media-level" - attributes and add information about the media stream. Attribute - fields can also be added before the first media field; these - "session-level" attributes convey additional information that applies - to the conference as a whole rather than to individual media; an - example might be the conference's floor control policy. - - Attribute fields may be of two forms: - - o property attributes. A property attribute is simply of the form - "a=". These are binary attributes, and the presence of the - attribute conveys that the attribute is a property of the session. - An example might be "a=recvonly". - - o value attributes. A value attribute is of the form - "a=:". An example might be that a whiteboard - could have the value attribute "a=orient:landscape" - - Attribute interpretation depends on the media tool being invoked. - Thus receivers of session descriptions should be configurable in - their interpretation of announcements in general and of attributes in - particular. - - Attribute names must be in the US-ASCII subset of ISO-10646/UTF-8. - - - - -Handley & Jacobson Standards Track [Page 18] - -RFC 2327 SDP April 1998 - - - Attribute values are byte strings, and MAY use any byte value except - 0x00 (Nul), 0x0A (LF), and 0x0D (CR). By default, attribute values - are to be interpreted as in ISO-10646 character set with UTF-8 - encoding. Unlike other text fields, attribute values are NOT - normally affected by the `charset' attribute as this would make - comparisons against known values problematic. However, when an - attribute is defined, it can be defined to be charset-dependent, in - which case it's value should be interpreted in the session charset - rather than in ISO-10646. - - Attributes that will be commonly used can be registered with IANA - (see Appendix B). Unregistered attributes should begin with "X-" to - prevent inadvertent collision with registered attributes. In either - case, if an attribute is received that is not understood, it should - simply be ignored by the receiver. - - Media Announcements - - m= - - A session description may contain a number of media descriptions. - Each media description starts with an "m=" field, and is terminated - by either the next "m=" field or by the end of the session - description. A media field also has several sub-fields: - - o The first sub-field is the media type. Currently defined media are - "audio", "video", "application", "data" and "control", though this - list may be extended as new communication modalities emerge (e.g., - telepresense). The difference between "application" and "data" is - that the former is a media flow such as whiteboard information, and - the latter is bulk-data transfer such as multicasting of program - executables which will not typically be displayed to the user. - "control" is used to specify an additional conference control - channel for the session. - - o The second sub-field is the transport port to which the media - stream will be sent. The meaning of the transport port depends on - the network being used as specified in the relevant "c" field and - on the transport protocol defined in the third sub-field. Other - ports used by the media application (such as the RTCP port, see - [2]) should be derived algorithmically from the base media port. - - Note: For transports based on UDP, the value should be in the range - 1024 to 65535 inclusive. For RTP compliance it should be an even - number. - - - - - - -Handley & Jacobson Standards Track [Page 19] - -RFC 2327 SDP April 1998 - - - For applications where hierarchically encoded streams are being - sent to a unicast address, it may be necessary to specify multiple - transport ports. This is done using a similar notation to that - used for IP multicast addresses in the "c=" field: - - m= / - - In such a case, the ports used depend on the transport protocol. - For RTP, only the even ports are used for data and the - corresponding one-higher odd port is used for RTCP. For example: - - m=video 49170/2 RTP/AVP 31 - - would specify that ports 49170 and 49171 form one RTP/RTCP pair and - 49172 and 49173 form the second RTP/RTCP pair. RTP/AVP is the - transport protocol and 31 is the format (see below). - - It is illegal for both multiple addresses to be specified in the - "c=" field and for multiple ports to be specified in the "m=" field - in the same session description. - - o The third sub-field is the transport protocol. The transport - protocol values are dependent on the address-type field in the "c=" - fields. Thus a "c=" field of IP4 defines that the transport - protocol runs over IP4. For IP4, it is normally expected that most - media traffic will be carried as RTP over UDP. The following - transport protocols are preliminarily defined, but may be extended - through registration of new protocols with IANA: - - - RTP/AVP - the IETF's Realtime Transport Protocol using the - Audio/Video profile carried over UDP. - - - udp - User Datagram Protocol - - If an application uses a single combined proprietary media format - and transport protocol over UDP, then simply specifying the - transport protocol as udp and using the format field to distinguish - the combined protocol is recommended. If a transport protocol is - used over UDP to carry several distinct media types that need to be - distinguished by a session directory, then specifying the transport - protocol and media format separately is necessary. RTP is an - example of a transport-protocol that carries multiple payload - formats that must be distinguished by the session directory for it - to know how to start appropriate tools, relays, mixers or - recorders. - - - - - - -Handley & Jacobson Standards Track [Page 20] - -RFC 2327 SDP April 1998 - - - The main reason to specify the transport-protocol in addition to - the media format is that the same standard media formats may be - carried over different transport protocols even when the network - protocol is the same - a historical example is vat PCM audio and - RTP PCM audio. In addition, relays and monitoring tools that are - transport-protocol-specific but format-independent are possible. - - For RTP media streams operating under the RTP Audio/Video Profile - [3], the protocol field is "RTP/AVP". Should other RTP profiles be - defined in the future, their profiles will be specified in the same - way. For example, the protocol field "RTP/XYZ" would specify RTP - operating under a profile whose short name is "XYZ". - - o The fourth and subsequent sub-fields are media formats. For audio - and video, these will normally be a media payload type as defined - in the RTP Audio/Video Profile. - - When a list of payload formats is given, this implies that all of - these formats may be used in the session, but the first of these - formats is the default format for the session. - - For media whose transport protocol is not RTP or UDP the format - field is protocol specific. Such formats should be defined in an - additional specification document. - - For media whose transport protocol is RTP, SDP can be used to - provide a dynamic binding of media encoding to RTP payload type. - The encoding names in the RTP AV Profile do not specify unique - audio encodings (in terms of clock rate and number of audio - channels), and so they are not used directly in SDP format fields. - Instead, the payload type number should be used to specify the - format for static payload types and the payload type number along - with additional encoding information should be used for dynamically - allocated payload types. - - An example of a static payload type is u-law PCM coded single - channel audio sampled at 8KHz. This is completely defined in the - RTP Audio/Video profile as payload type 0, so the media field for - such a stream sent to UDP port 49232 is: - - m=video 49232 RTP/AVP 0 - - An example of a dynamic payload type is 16 bit linear encoded - stereo audio sampled at 16KHz. If we wish to use dynamic RTP/AVP - payload type 98 for such a stream, additional information is - required to decode it: - - m=video 49232 RTP/AVP 98 - - - -Handley & Jacobson Standards Track [Page 21] - -RFC 2327 SDP April 1998 - - - a=rtpmap:98 L16/16000/2 - - The general form of an rtpmap attribute is: - - a=rtpmap: /[/] - - For audio streams, may specify the number of - audio channels. This parameter may be omitted if the number of - channels is one provided no additional parameters are needed. For - video streams, no encoding parameters are currently specified. - - Additional parameters may be defined in the future, but - codecspecific parameters should not be added. Parameters added to - an rtpmap attribute should only be those required for a session - directory to make the choice of appropriate media too to - participate in a session. Codec-specific parameters should be - added in other attributes. - - Up to one rtpmap attribute can be defined for each media format - specified. Thus we might have: - - m=audio 49230 RTP/AVP 96 97 98 - a=rtpmap:96 L8/8000 - a=rtpmap:97 L16/8000 - a=rtpmap:98 L16/11025/2 - - RTP profiles that specify the use of dynamic payload types must - define the set of valid encoding names and/or a means to register - encoding names if that profile is to be used with SDP. - - Experimental encoding formats can also be specified using rtpmap. - RTP formats that are not registered as standard format names must - be preceded by "X-". Thus a new experimental redundant audio - stream called GSMLPC using dynamic payload type 99 could be - specified as: - - m=video 49232 RTP/AVP 99 - a=rtpmap:99 X-GSMLPC/8000 - - Such an experimental encoding requires that any site wishing to - receive the media stream has relevant configured state in its - session directory to know which tools are appropriate. - - Note that RTP audio formats typically do not include information - about the number of samples per packet. If a non-default (as - defined in the RTP Audio/Video Profile) packetisation is required, - the "ptime" attribute is used as given below. - - - -Handley & Jacobson Standards Track [Page 22] - -RFC 2327 SDP April 1998 - - - For more details on RTP audio and video formats, see [3]. - - o Formats for non-RTP media should be registered as MIME content - types as described in Appendix B. For example, the LBL whiteboard - application might be registered as MIME content-type application/wb - with encoding considerations specifying that it operates over UDP, - with no appropriate file format. In SDP this would then be - expressed using a combination of the "media" field and the "fmt" - field, as follows: - - m=application 32416 udp wb - - Suggested Attributes - - The following attributes are suggested. Since application writers - may add new attributes as they are required, this list is not - exhaustive. - - a=cat: - This attribute gives the dot-separated hierarchical category of - the session. This is to enable a receiver to filter unwanted - sessions by category. It would probably have been a compulsory - separate field, except for its experimental nature at this time. - It is a session-level attribute, and is not dependent on charset. - - a=keywds: - Like the cat attribute, this is to assist identifying wanted - sessions at the receiver. This allows a receiver to select - interesting session based on keywords describing the purpose of - the session. It is a session-level attribute. It is a charset - dependent attribute, meaning that its value should be interpreted - in the charset specified for the session description if one is - specified, or by default in ISO 10646/UTF-8. - - a=tool: - This gives the name and version number of the tool used to create - the session description. It is a session-level attribute, and is - not dependent on charset. - - a=ptime: - This gives the length of time in milliseconds represented by the - media in a packet. This is probably only meaningful for audio - data. It should not be necessary to know ptime to decode RTP or - vat audio, and it is intended as a recommendation for the - encoding/packetisation of audio. It is a media attribute, and is - not dependent on charset. - - - - - -Handley & Jacobson Standards Track [Page 23] - -RFC 2327 SDP April 1998 - - - a=recvonly - This specifies that the tools should be started in receive-only - mode where applicable. It can be either a session or media - attribute, and is not dependent on charset. - - a=sendrecv - This specifies that the tools should be started in send and - receive mode. This is necessary for interactive conferences with - tools such as wb which defaults to receive only mode. It can be - either a session or media attribute, and is not dependent on - charset. - - a=sendonly - This specifies that the tools should be started in send-only - mode. An example may be where a different unicast address is to - be used for a traffic destination than for a traffic source. In - such a case, two media descriptions may be use, one sendonly and - one recvonly. It can be either a session or media attribute, but - would normally only be used as a media attribute, and is not - dependent on charset. - - a=orient: - Normally this is only used in a whiteboard media specification. - It specifies the orientation of a the whiteboard on the screen. - It is a media attribute. Permitted values are `portrait', - `landscape' and `seascape' (upside down landscape). It is not - dependent on charset - - a=type: - This specifies the type of the conference. Suggested values are - `broadcast', `meeting', `moderated', `test' and `H332'. - `recvonly' should be the default for `type:broadcast' sessions, - `type:meeting' should imply `sendrecv' and `type:moderated' - should indicate the use of a floor control tool and that the - media tools are started so as to "mute" new sites joining the - conference. - - Specifying the attribute type:H332 indicates that this loosely - coupled session is part of a H.332 session as defined in the ITU - H.332 specification [10]. Media tools should be started - `recvonly'. - - Specifying the attribute type:test is suggested as a hint that, - unless explicitly requested otherwise, receivers can safely avoid - displaying this session description to users. - - The type attribute is a session-level attribute, and is not - dependent on charset. - - - -Handley & Jacobson Standards Track [Page 24] - -RFC 2327 SDP April 1998 - - - a=charset: - This specifies the character set to be used to display the - session name and information data. By default, the ISO-10646 - character set in UTF-8 encoding is used. If a more compact - representation is required, other character sets may be used such - as ISO-8859-1 for Northern European languages. In particular, - the ISO 8859-1 is specified with the following SDP attribute: - - a=charset:ISO-8859-1 - - This is a session-level attribute; if this attribute is present, - it must be before the first media field. The charset specified - MUST be one of those registered with IANA, such as ISO-8859-1. - The character set identifier is a US-ASCII string and MUST be - compared against the IANA identifiers using a case-insensitive - comparison. If the identifier is not recognised or not - supported, all strings that are affected by it SHOULD be regarded - as byte strings. - - Note that a character set specified MUST still prohibit the use - of bytes 0x00 (Nul), 0x0A (LF) and 0x0d (CR). Character sets - requiring the use of these characters MUST define a quoting - mechanism that prevents these bytes appearing within text fields. - - a=sdplang: - This can be a session level attribute or a media level attribute. - As a session level attribute, it specifies the language for the - session description. As a media level attribute, it specifies - the language for any media-level SDP information field associated - with that media. Multiple sdplang attributes can be provided - either at session or media level if multiple languages in the - session description or media use multiple languages, in which - case the order of the attributes indicates the order of - importance of the various languages in the session or media from - most important to least important. - - In general, sending session descriptions consisting of multiple - languages should be discouraged. Instead, multiple descriptions - should be sent describing the session, one in each language. - However this is not possible with all transport mechanisms, and - so multiple sdplang attributes are allowed although not - recommended. - - The sdplang attribute value must be a single RFC 1766 language - tag in US-ASCII. It is not dependent on the charset attribute. - An sdplang attribute SHOULD be specified when a session is of - - - - - -Handley & Jacobson Standards Track [Page 25] - -RFC 2327 SDP April 1998 - - - sufficient scope to cross geographic boundaries where the - language of recipients cannot be assumed, or where the session is - in a different language from the locally assumed norm. - - a=lang: - This can be a session level attribute or a media level attribute. - As a session level attribute, it specifies the default language - for the session being described. As a media level attribute, it - specifies the language for that media, overriding any session- - level language specified. Multiple lang attributes can be - provided either at session or media level if multiple languages - if the session description or media use multiple languages, in - which case the order of the attributes indicates the order of - importance of the various languages in the session or media from - most important to least important. - - The lang attribute value must be a single RFC 1766 language tag - in US-ASCII. It is not dependent on the charset attribute. A - lang attribute SHOULD be specified when a session is of - sufficient scope to cross geographic boundaries where the - language of recipients cannot be assumed, or where the session is - in a different language from the locally assumed norm. - - a=framerate: - This gives the maximum video frame rate in frames/sec. It is - intended as a recommendation for the encoding of video data. - Decimal representations of fractional values using the notation - "." are allowed. It is a media attribute, is - only defined for video media, and is not dependent on charset. - - a=quality: - This gives a suggestion for the quality of the encoding as an - integer value. - - The intention of the quality attribute for video is to specify a - non-default trade-off between frame-rate and still-image quality. - For video, the value in the range 0 to 10, with the following - suggested meaning: - - 10 - the best still-image quality the compression scheme can - give. - - 5 - the default behaviour given no quality suggestion. - - 0 - the worst still-image quality the codec designer thinks is - still usable. - - It is a media attribute, and is not dependent on charset. - - - -Handley & Jacobson Standards Track [Page 26] - -RFC 2327 SDP April 1998 - - - a=fmtp: - This attribute allows parameters that are specific to a - particular format to be conveyed in a way that SDP doesn't have - to understand them. The format must be one of the formats - specified for the media. Format-specific parameters may be any - set of parameters required to be conveyed by SDP and given - unchanged to the media tool that will use this format. - - It is a media attribute, and is not dependent on charset. - -6.1. Communicating Conference Control Policy - - There is some debate over the way conference control policy should be - communicated. In general, the authors believe that an implicit - declarative style of specifying conference control is desirable where - possible. - - A simple declarative style uses a single conference attribute field - before the first media field, possibly supplemented by properties - such as `recvonly' for some of the media tools. This conference - attribute conveys the conference control policy. An example might be: - - a=type:moderated - - In some cases, however, it is possible that this may be insufficient - to communicate the details of an unusual conference control policy. - If this is the case, then a conference attribute specifying external - control might be set, and then one or more "media" fields might be - used to specify the conference control tools and configuration data - for those tools. An example is an ITU H.332 session: - - c=IN IP4 224.5.6.7 - a=type:H332 - m=audio 49230 RTP/AVP 0 - m=video 49232 RTP/AVP 31 - m=application 12349 udp wb - m=control 49234 H323 mc - c=IN IP4 134.134.157.81 - - In this example, a general conference attribute (type:H332) is - specified stating that conference control will be provided by an - external H.332 tool, and a contact addresses for the H.323 session - multipoint controller is given. - - In this document, only the declarative style of conference control - declaration is specified. Other forms of conference control should - specify an appropriate type attribute, and should define the - implications this has for control media. - - - -Handley & Jacobson Standards Track [Page 27] - -RFC 2327 SDP April 1998 - - -7. Security Considerations - - SDP is a session description format that describes multimedia - sessions. A session description should not be trusted unless it has - been obtained by an authenticated transport protocol from a trusted - source. Many different transport protocols may be used to distribute - session description, and the nature of the authentication will differ - from transport to transport. - - One transport that will frequently be used to distribute session - descriptions is the Session Announcement Protocol (SAP). SAP - provides both encryption and authentication mechanisms but due to the - nature of session announcements it is likely that there are many - occasions where the originator of a session announcement cannot be - authenticated because they are previously unknown to the receiver of - the announcement and because no common public key infrastructure is - available. - - On receiving a session description over an unauthenticated transport - mechanism or from an untrusted party, software parsing the session - should take a few precautions. Session description contain - information required to start software on the receivers system. - Software that parses a session description MUST not be able to start - other software except that which is specifically configured as - appropriate software to participate in multimedia sessions. It is - normally considered INAPPROPRIATE for software parsing a session - description to start, on a user's system, software that is - appropriate to participate in multimedia sessions, without the user - first being informed that such software will be started and giving - their consent. Thus a session description arriving by session - announcement, email, session invitation, or WWW page SHOULD not - deliver the user into an {it interactive} multimedia session without - the user being aware that this will happen. As it is not always - simple to tell whether a session is interactive or not, applications - that are unsure should assume sessions are interactive. - - In this specification, there are no attributes which would allow the - recipient of a session description to be informed to start multimedia - tools in a mode where they default to transmitting. Under some - circumstances it might be appropriate to define such attributes. If - this is done an application parsing a session description containing - such attributes SHOULD either ignore them, or inform the user that - joining this session will result in the automatic transmission of - multimedia data. The default behaviour for an unknown attribute is - to ignore it. - - - - - - -Handley & Jacobson Standards Track [Page 28] - -RFC 2327 SDP April 1998 - - - Session descriptions may be parsed at intermediate systems such as - firewalls for the purposes of opening a hole in the firewall to allow - the participation in multimedia sessions. It is considered - INAPPROPRIATE for a firewall to open such holes for unicast data - streams unless the session description comes in a request from inside - the firewall. - - For multicast sessions, it is likely that local administrators will - apply their own policies, but the exclusive use of "local" or "site- - local" administrative scope within the firewall and the refusal of - the firewall to open a hole for such scopes will provide separation - of global multicast sessions from local ones. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Handley & Jacobson Standards Track [Page 29] - -RFC 2327 SDP April 1998 - - -Appendix A: SDP Grammar - - This appendix provides an Augmented BNF grammar for SDP.

Using - the terminology in the SDP specification BNF, they are "media", - "proto", "fmt", "att-field", "bwtype", "nettype" and "addrtype". - - "media" (eg, audio, video, application, data). - - Packetized media types, such as those used by RTP, share the - namespace used by media types registry [RFC 2048] (i.e. "MIME - types"). The list of valid media names is the set of top-level - MIME content types. The set of media is intended to be small and - not to be extended except under rare circumstances. (The MIME - subtype corresponds to the "fmt" parameter below). - - "proto" - - In general this should be an IETF standards-track transport - protocol identifier such as RTP/AVP (rfc 1889 under the rfc 1890 - profile). - - However, people will want to invent their own proprietary - transport protocols. Some of these should be registered as a - "fmt" using "udp" as the protocol and some of which probably - can't be. - - Where the protocol and the application are intimately linked, - such as with the LBL whiteboard wb which used a proprietary and - special purpose protocol over UDP, the protocol name should be - "udp" and the format name that should be registered is "wb". The - rules for formats (see below) apply to such registrations. - - Where the proprietary transport protocol really carries many - different data formats, it is possible to register a new protocol - name with IANA. In such a case, an RFC MUST be produced - describing the protocol and referenced in the registration. Such - an RFC MAY be informational, although it is preferable if it is - standards-track. - - "fmt" - - The format namespace is dependent on the context of the "proto" - field, so a format cannot be registered without specifying one or - more transport protocols that it applies to. - - Formats cover all the possible encodings that might want to be - transported in a multimedia session. - - - - -Handley & Jacobson Standards Track [Page 36] - -RFC 2327 SDP April 1998 - - - For RTP formats that have been assigned static payload types, the - payload type number is used. For RTP formats using a dynamic - payload type number, the dynamic payload type number is given as - the format and an additional "rtpmap" attribute specifies the - format and parameters. - - For non-RTP formats, any unregistered format name may be - registered through the MIME-type registration process [RFC 2048]. - The type given here is the MIME subtype only (the top-level MIME - content type is specified by the media parameter). The MIME type - registration SHOULD reference a standards-track RFC which - describes the transport protocol for this media type. If there - is an existing MIME type for this format, the MIME registration - should be augmented to reference the transport specification for - this media type. If there is not an existing MIME type for this - format, and there exists no appropriate file format, this should - be noted in the encoding considerations as "no appropriate file - format". - - "att-field" (Attribute names) - - Attribute field names MAY be registered with IANA, although this - is not compulsory, and unknown attributes are simply ignored. - - When an attribute is registered, it must be accompanied by a - brief specification stating the following: - - o contact name, email address and telephone number - - o attribute-name (as it will appear in SDP) - - o long-form attribute name in English - - o type of attribute (session level, media level, or both) - - o whether the attribute value is subject to the charset - attribute. - - o a one paragraph explanation of the purpose of the attribute. - - o a specification of appropriate attribute values for this - attribute. - - IANA will not sanity check such attribute registrations except to - ensure that they do not clash with existing registrations. - - - - - - -Handley & Jacobson Standards Track [Page 37] - -RFC 2327 SDP April 1998 - - - Although the above is the minimum that IANA will accept, if the - attribute is expected to see widespread use and interoperability - is an issue, authors are encouraged to produce a standards-track - RFC that specifies the attribute more precisely. - - Submitters of registrations should ensure that the specification - is in the spirit of SDP attributes, most notably that the - attribute is platform independent in the sense that it makes no - implicit assumptions about operating systems and does not name - specific pieces of software in a manner that might inhibit - interoperability. - - "bwtype" (bandwidth specifiers) - - A proliferation of bandwidth specifiers is strongly discouraged. - - New bandwidth specifiers may be registered with IANA. The - submission MUST reference a standards-track RFC specifying the - semantics of the bandwidth specifier precisely, and indicating - when it should be used, and why the existing registered bandwidth - specifiers do not suffice. - - "nettype" (Network Type) - - New network types may be registered with IANA if SDP needs to be - used in the context of non-internet environments. Whilst these - are not normally the preserve of IANA, there may be circumstances - when an Internet application needs to interoperate with a non- - internet application, such as when gatewaying an internet - telephony call into the PSTN. The number of network types should - be small and should be rarely extended. A new network type - cannot be registered without registering at least one address - type to be used with that network type. A new network type - registration MUST reference an RFC which gives details of the - network type and address type and specifies how and when they - would be used.

Standards Track [Page 6] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -1 Introduction - -1.1 Overview of SIP Functionality - - The Session Initiation Protocol (SIP) is an application-layer control - protocol that can establish, modify and terminate multimedia sessions - or calls. These multimedia sessions include multimedia conferences, - distance learning, Internet telephony and similar applications. SIP - can invite both persons and "robots", such as a media storage - service. SIP can invite parties to both unicast and multicast - sessions; the initiator does not necessarily have to be a member of - the session to which it is inviting. Media and participants can be - added to an existing session. - - SIP can be used to initiate sessions as well as invite members to - sessions that have been advertised and established by other means. - Sessions can be advertised using multicast protocols such as SAP, - electronic mail, news groups, web pages or directories (LDAP), among - others. - - SIP transparently supports name mapping and redirection services, - allowing the implementation of ISDN and Intelligent Network telephony - subscriber services. These facilities also enable personal mobility. - In the parlance of telecommunications intelligent network services, - this is defined as: "Personal mobility is the ability of end users to - originate and receive calls and access subscribed telecommunication - services on any terminal in any location, and the ability of the - network to identify end users as they move. Personal mobility is - based on the use of a unique personal identity (i.e., personal - number)." [1]. Personal mobility complements terminal mobility, i.e., - the ability to maintain communications when moving a single end - system from one subnet to another. - - SIP supports five facets of establishing and terminating multimedia - communications: - - User location: determination of the end system to be used for - communication; - - User capabilities: determination of the media and media parameters to - be used; - - User availability: determination of the willingness of the called - party to engage in communications; - - Call setup: "ringing", establishment of call parameters at both - called and calling party; - - - - -Handley, et al. Standards Track [Page 7] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Call handling: including transfer and termination of calls. - - SIP can also initiate multi-party calls using a multipoint control - unit (MCU) or fully-meshed interconnection instead of multicast. - Internet telephony gateways that connect Public Switched Telephone - Network (PSTN) parties can also use SIP to set up calls between them. - - SIP is designed as part of the overall IETF multimedia data and - control architecture currently incorporating protocols such as RSVP - (RFC 2205 [2]) for reserving network resources, the real-time - transport protocol (RTP) (RFC 1889 [3]) for transporting real-time - data and providing QOS feedback, the real-time streaming protocol - (RTSP) (RFC 2326 [4]) for controlling delivery of streaming media, - the session announcement protocol (SAP) [5] for advertising - multimedia sessions via multicast and the session description - protocol (SDP) (RFC 2327 [6]) for describing multimedia sessions. - However, the functionality and operation of SIP does not depend on - any of these protocols. - - SIP can also be used in conjunction with other call setup and - signaling protocols. In that mode, an end system uses SIP exchanges - to determine the appropriate end system address and protocol from a - given address that is protocol-independent. For example, SIP could be - used to determine that the party can be reached via H.323 [7], obtain - the H.245 [8] gateway and user address and then use H.225.0 [9] to - establish the call. - - In another example, SIP might be used to determine that the callee is - reachable via the PSTN and indicate the phone number to be called, - possibly suggesting an Internet-to-PSTN gateway to be used. - - SIP does not offer conference control services such as floor control - or voting and does not prescribe how a conference is to be managed, - but SIP can be used to introduce conference control protocols. SIP - does not allocate multicast addresses. - - SIP can invite users to sessions with and without resource - reservation. SIP does not reserve resources, but can convey to the - invited system the information necessary to do this. - -1.2 Terminology - - In this document, the key words "MUST", "MUST NOT", "REQUIRED", - "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", - and "OPTIONAL" are to be interpreted as described in RFC 2119 [10] - and indicate requirement levels for compliant SIP implementations. - - - - - -Handley, et al. Standards Track [Page 8] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -1.3 Definitions - - This specification uses a number of terms to refer to the roles - played by participants in SIP communications. The definitions of - client, server and proxy are similar to those used by the Hypertext - Transport Protocol (HTTP) (RFC 2068 [11]). The terms and generic - syntax of URI and URL are defined in RFC 2396 [12]. The following - terms have special significance for SIP. - - Call: A call consists of all participants in a conference invited by - a common source. A SIP call is identified by a globally unique - call-id (Section 6.12). Thus, if a user is, for example, invited - to the same multicast session by several people, each of these - invitations will be a unique call. A point-to-point Internet - telephony conversation maps into a single SIP call. In a - multiparty conference unit (MCU) based call-in conference, each - participant uses a separate call to invite himself to the MCU. - - Call leg: A call leg is identified by the combination of Call-ID, To - and From. - - Client: An application program that sends SIP requests. Clients may - or may not interact directly with a human user. User agents and - proxies contain clients (and servers). - - Conference: A multimedia session (see below), identified by a common - session description. A conference can have zero or more members - and includes the cases of a multicast conference, a full-mesh - conference and a two-party "telephone call", as well as - combinations of these. Any number of calls can be used to - create a conference. - - Downstream: Requests sent in the direction from the caller to the - callee (i.e., user agent client to user agent server). - - Final response: A response that terminates a SIP transaction, as - opposed to a provisional response that does not. All 2xx, 3xx, - 4xx, 5xx and 6xx responses are final. - - Initiator, calling party, caller: The party initiating a conference - invitation. Note that the calling party does not have to be the - same as the one creating the conference. - - Invitation: A request sent to a user (or service) requesting - participation in a session. A successful SIP invitation consists - of two transactions: an INVITE request followed by an ACK - request. - - - - -Handley, et al. Standards Track [Page 9] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Invitee, invited user, called party, callee: The person or service - that the calling party is trying to invite to a conference. - - Isomorphic request or response: Two requests or responses are defined - to be isomorphic for the purposes of this document if they have - the same values for the Call-ID, To, From and CSeq header - fields. In addition, isomorphic requests have to have the same - Request-URI. - - Location server: See location service. - - Location service: A location service is used by a SIP redirect or - proxy server to obtain information about a callee's possible - location(s). Location services are offered by location servers. - Location servers MAY be co-located with a SIP server, but the - manner in which a SIP server requests location services is - beyond the scope of this document. - - Parallel search: In a parallel search, a proxy issues several - requests to possible user locations upon receiving an incoming - request. Rather than issuing one request and then waiting for - the final response before issuing the next request as in a - sequential search , a parallel search issues requests without - waiting for the result of previous requests. - - Provisional response: A response used by the server to indicate - progress, but that does not terminate a SIP transaction. 1xx - responses are provisional, other responses are considered final. - - Proxy, proxy server: An intermediary program that acts as both a - server and a client for the purpose of making requests on behalf - of other clients. Requests are serviced internally or by passing - them on, possibly after translation, to other servers. A proxy - interprets, and, if necessary, rewrites a request message before - forwarding it. - - Redirect server: A redirect server is a server that accepts a SIP - request, maps the address into zero or more new addresses and - returns these addresses to the client. Unlike a proxy server , - it does not initiate its own SIP request. Unlike a user agent - server , it does not accept calls. - - Registrar: A registrar is a server that accepts REGISTER requests. A - registrar is typically co-located with a proxy or redirect - server and MAY offer location services. - - - - - - -Handley, et al. Standards Track [Page 10] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Ringback: Ringback is the signaling tone produced by the calling - client's application indicating that a called party is being - alerted (ringing). - - Server: A server is an application program that accepts requests in - order to service requests and sends back responses to those - requests. Servers are either proxy, redirect or user agent - servers or registrars. - - Session: From the SDP specification: "A multimedia session is a set - of multimedia senders and receivers and the data streams flowing - from senders to receivers. A multimedia conference is an example - of a multimedia session." (RFC 2327 [6]) (A session as defined - for SDP can comprise one or more RTP sessions.) As defined, a - callee can be invited several times, by different calls, to the - same session. If SDP is used, a session is defined by the - concatenation of the user name , session id , network type , - address type and address elements in the origin field. - - (SIP) transaction: A SIP transaction occurs between a client and a - server and comprises all messages from the first request sent - from the client to the server up to a final (non-1xx) response - sent from the server to the client. A transaction is identified - by the CSeq sequence number (Section 6.17) within a single call - leg. The ACK request has the same CSeq number as the - corresponding INVITE request, but comprises a transaction of its - own. - - Upstream: Responses sent in the direction from the user agent server - to the user agent client. - - URL-encoded: A character string encoded according to RFC 1738, - Section 2.2 [13]. - - User agent client (UAC), calling user agent: A user agent client is a - client application that initiates the SIP request. - - User agent server (UAS), called user agent: A user agent server is a - server application that contacts the user when a SIP request is - received and that returns a response on behalf of the user. The - response accepts, rejects or redirects the request. - - User agent (UA): An application which contains both a user agent - client and user agent server. - - An application program MAY be capable of acting both as a client and - a server. For example, a typical multimedia conference control - application would act as a user agent client to initiate calls or to - - - -Handley, et al.

When making a SIP call, a caller first locates the - appropriate server (Section 1.4.2) and then sends a SIP request - (Section 1.4.3). The most common SIP operation is the invitation - (Section 1.4.4). Instead of directly reaching the intended callee, a - SIP request may be redirected or may trigger a chain of new SIP - requests by proxies (Section 1.4.5). Users can register their - location(s) with SIP servers (Section 4.2.6). - -1.4.1 SIP Addressing - - The "objects" addressed by SIP are users at hosts, identified by a - SIP URL. The SIP URL takes a form similar to a mailto or telnet URL, - i.e., user@host. The user part is a user name or a telephone number. - The host part is either a domain name or a numeric network address. - See section 2 for a detailed discussion of SIP URL's. - - A user's SIP address can be obtained out-of-band, can be learned via - existing media agents, can be included in some mailers' message - headers, or can be recorded during previous invitation interactions. - In many cases, a user's SIP URL can be guessed from their email - address. - - - - -Handley, et al. Standards Track [Page 12] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - A SIP URL address can designate an individual (possibly located at - one of several end systems), the first available person from a group - of individuals or a whole group. The form of the address, for - example, sip:sales@example.com , is not sufficient, in general, to - determine the intent of the caller. - - If a user or service chooses to be reachable at an address that is - guessable from the person's name and organizational affiliation, the - traditional method of ensuring privacy by having an unlisted "phone" - number is compromised. However, unlike traditional telephony, SIP - offers authentication and access control mechanisms and can avail - itself of lower-layer security mechanisms, so that client software - can reject unauthorized or undesired call attempts. - -1.4.2 Locating a SIP Server - - When a client wishes to send a request, the client either sends it to - a locally configured SIP proxy server (as in HTTP), independent of - the Request-URI, or sends it to the IP address and port corresponding - to the Request-URI. - - For the latter case, the client must determine the protocol, port and - IP address of a server to which to send the request. A client SHOULD - follow the steps below to obtain this information, but MAY follow the - alternative, optional procedure defined in Appendix D. At each step, - unless stated otherwise, the client SHOULD try to contact a server at - the port number listed in the Request-URI. If no port number is - present in the Request-URI, the client uses port 5060. If the - Request-URI specifies a protocol (TCP or UDP), the client contacts - the server using that protocol. If no protocol is specified, the - client tries UDP (if UDP is supported). If the attempt fails, or if - the client doesn't support UDP but supports TCP, it then tries TCP. - - A client SHOULD be able to interpret explicit network notifications - (such as ICMP messages) which indicate that a server is not - reachable, rather than relying solely on timeouts. (For socket-based - programs: For TCP, connect() returns ECONNREFUSED if the client could - not connect to a server at that address. For UDP, the socket needs to - be bound to the destination address using connect() rather than - sendto() or similar so that a second write() fails with ECONNREFUSED - if there is no server listening) If the client finds the server is - not reachable at a particular address, it SHOULD behave as if it had - received a 400-class error response to that request. - - The client tries to find one or more addresses for the SIP server by - querying DNS. The procedure is as follows: - - - - - -Handley, et al. Standards Track [Page 13] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - 1. If the host portion of the Request-URI is an IP address, - the client contacts the server at the given address. - Otherwise, the client proceeds to the next step. - - 2. The client queries the DNS server for address records for - the host portion of the Request-URI. If the DNS server - returns no address records, the client stops, as it has - been unable to locate a server. By address record, we mean - A RR's, AAAA RR's, or other similar address records, chosen - according to the client's network protocol capabilities. - - - There are no mandatory rules on how to select a host name - for a SIP server. Users are encouraged to name their SIP - servers using the sip.domainname (i.e., sip.example.com) - convention, as specified in RFC 2219 [16]. Users may only - know an email address instead of a full SIP URL for a - callee, however. In that case, implementations may be able - to increase the likelihood of reaching a SIP server for - that domain by constructing a SIP URL from that email - address by prefixing the host name with "sip.". In the - future, this mechanism is likely to become unnecessary as - better DNS techniques, such as the one in Appendix D, - become widely available. - - A client MAY cache a successful DNS query result. A successful query - is one which contained records in the answer, and a server was - contacted at one of the addresses from the answer. When the client - wishes to send a request to the same host, it MUST start the search - as if it had just received this answer from the name server. The - client MUST follow the procedures in RFC1035 [15] regarding DNS cache - invalidation when the DNS time-to-live expires. - -1.4.3 SIP Transaction - - Once the host part has been resolved to a SIP server, the client - sends one or more SIP requests to that server and receives one or - more responses from the server. A request (and its retransmissions) - together with the responses triggered by that request make up a SIP - transaction. All responses to a request contain the same values in - the Call-ID, CSeq, To, and From fields (with the possible addition of - a tag in the To field (section 6.37)). This allows responses to be - matched with requests. The ACK request following an INVITE is not - part of the transaction since it may traverse a different set of - hosts. - - - - - - -Handley, et al. Standards Track [Page 14] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - If TCP is used, request and responses within a single SIP transaction - are carried over the same TCP connection (see Section 10). Several - SIP requests from the same client to the same server MAY use the same - TCP connection or MAY use a new connection for each request. - - If the client sent the request via unicast UDP, the response is sent - to the address contained in the next Via header field (Section 6.40) - of the response. If the request is sent via multicast UDP, the - response is directed to the same multicast address and destination - port. For UDP, reliability is achieved using retransmission (Section - 10). - - The SIP message format and operation is independent of the transport - protocol. - -1.4.4 SIP Invitation - - A successful SIP invitation consists of two requests, INVITE followed - by ACK. The INVITE (Section 4.2.1) request asks the callee to join a - particular conference or establish a two-party conversation. After - the callee has agreed to participate in the call, the caller confirms - that it has received that response by sending an ACK (Section 4.2.2) - request. If the caller no longer wants to participate in the call, it - sends a BYE request instead of an ACK. - - The INVITE request typically contains a session description, for - example written in SDP (RFC 2327 [6]) format, that provides the - called party with enough information to join the session. For - multicast sessions, the session description enumerates the media - types and formats that are allowed to be distributed to that session. - For a unicast session, the session description enumerates the media - types and formats that the caller is willing to use and where it - wishes the media data to be sent. In either case, if the callee - wishes to accept the call, it responds to the invitation by returning - a similar description listing the media it wishes to use. For a - multicast session, the callee SHOULD only return a session - description if it is unable to receive the media indicated in the - caller's description or wants to receive data via unicast. - - The protocol exchanges for the INVITE method are shown in Fig. 1 for - a proxy server and in Fig. 2 for a redirect server. (Note that the - messages shown in the figures have been abbreviated slightly.) In - Fig. 1, the proxy server accepts the INVITE request (step 1), - contacts the location service with all or parts of the address (step - 2) and obtains a more precise location (step 3). The proxy server - then issues a SIP INVITE request to the address(es) returned by the - location service (step 4). The user agent server alerts the user - (step 5) and returns a success indication to the proxy server (step - - - -Handley, et al. Standards Track [Page 15] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - 6). The proxy server then returns the success result to the original - caller (step 7). The receipt of this message is confirmed by the - caller using an ACK request, which is forwarded to the callee (steps - 8 and 9). Note that an ACK can also be sent directly to the callee, - bypassing the proxy. All requests and responses have the same Call- - ID. - - - - - - +....... cs.columbia.edu .......+ - : : - : (~~~~~~~~~~) : - : ( location ) : - : ( service ) : - : (~~~~~~~~~~) : - : ^ | : - : | hgs@lab : - : 2| 3| : - : | | : - : henning | : -+.. cs.tu-berlin.de ..+ 1: INVITE : | | : -: : henning@cs.col: | \/ 4: INVITE 5: ring : -: cz@cs.tu-berlin.de ========================>(~~~~~~)=========>(~~~~~~) : -: <........................( )<.........( ) : -: : 7: 200 OK : ( )6: 200 OK ( ) : -: : : ( work ) ( lab ) : -: : 8: ACK : ( )9: ACK ( ) : -: ========================>(~~~~~~)=========>(~~~~~~) : -+.....................+ +...............................+ - - ====> SIP request - ....> SIP response - - ^ - | non-SIP protocols - | - - - Figure 1: Example of SIP proxy server - - - - The redirect server shown in Fig. 2 accepts the INVITE request (step - 1), contacts the location service as before (steps 2 and 3) and, - instead of contacting the newly found address itself, returns the - address to the caller (step 4), which is then acknowledged via an ACK - - - -Handley, et al. Standards Track [Page 16] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - request (step 5). The caller issues a new request, with the same - call-ID but a higher CSeq, to the address returned by the first - server (step 6). In the example, the call succeeds (step 7). The - caller and callee complete the handshake with an ACK (step 8). - - - The next section discusses what happens if the location service - returns more than one possible alternative. - -1.4.5 Locating a User - - A callee may move between a number of different end systems over - time. These locations can be dynamically registered with the SIP - server (Sections 1.4.7, 4.2.6). A location server MAY also use one or - more other protocols, such as finger (RFC 1288 [17]), rwhois (RFC - 2167 [18]), LDAP (RFC 1777 [19]), multicast-based protocols [20] or - operating-system dependent mechanisms to actively determine the end - system where a user might be reachable. A location server MAY return - several locations because the user is logged in at several hosts - simultaneously or because the location server has (temporarily) - inaccurate information. The SIP server combines the results to yield - a list of a zero or more locations. - - The action taken on receiving a list of locations varies with the - type of SIP server. A SIP redirect server returns the list to the - client as Contact headers (Section 6.13). A SIP proxy server can - sequentially or in parallel try the addresses until the call is - successful (2xx response) or the callee has declined the call (6xx - response). With sequential attempts, a proxy server can implement an - "anycast" service. - - If a proxy server forwards a SIP request, it MUST add itself to the - beginning of the list of forwarders noted in the Via (Section 6.40) - headers. The Via trace ensures that replies can take the same path - back, ensuring correct operation through compliant firewalls and - avoiding request loops. On the response path, each host MUST remove - its Via, so that routing internal information is hidden from the - callee and outside networks. A proxy server MUST check that it does - not generate a request to a host listed in the Via sent-by, via- - received or via-maddr parameters (Section 6.40). (Note: If a host has - several names or network addresses, this does not always work. Thus, - each host also checks if it is part of the Via list.) - - A SIP invitation may traverse more than one SIP proxy server. If one - of these "forks" the request, i.e., issues more than one request in - response to receiving the invitation request, it is possible that a - client is reached, independently, by more than one copy of the - - - - -Handley, et al. Standards Track [Page 17] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - invitation request. Each of these copies bears the same Call-ID. The - user agent MUST return the same status response returned in the first - response. Duplicate requests are not an error. - -1.4.6 Changing an Existing Session - - In some circumstances, it is desirable to change the parameters of an - existing session. This is done by re-issuing the INVITE, using the - same Call-ID, but a new or different body or header fields to convey - the new information. This re INVITE MUST have a higher CSeq than any - previous request from the client to the server. - - For example, two parties may have been conversing and then want to - add a third party, switching to multicast for efficiency. One of the - participants invites the third party with the new multicast address - and simultaneously sends an INVITE to the second party, with the new - multicast session description, but with the old call identifier. - -1.4.7 Registration Services - - The REGISTER request allows a client to let a proxy or redirect - server know at which address(es) it can be reached. A client MAY also - use it to install call handling features at the server. - -1.5 Protocol Properties - -1.5.1 Minimal State - - A single conference session or call involves one or more SIP - request-response transactions. Proxy servers do not have to keep - state for a particular call, however, they MAY maintain state for a - single SIP transaction, as discussed in Section 12. For efficiency, a - server MAY cache the results of location service requests. - -1.5.2 Lower-Layer-Protocol Neutral - - SIP makes minimal assumptions about the underlying transport and - network-layer protocols. The lower-layer can provide either a packet - or a byte stream service, with reliable or unreliable service. - - In an Internet context, SIP is able to utilize both UDP and TCP as - transport protocols, among others. UDP allows the application to more - carefully control the timing of messages and their retransmission, to - perform parallel searches without requiring TCP connection state for - each outstanding request, and to use multicast. Routers can more - readily snoop SIP UDP packets. TCP allows easier passage through - existing firewalls. - - - - -Handley, et al.

Standards Track [Page 19] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - When TCP is used, SIP can use one or more connections to attempt to - contact a user or to modify parameters of an existing conference. - Different SIP requests for the same SIP call MAY use different TCP - connections or a single persistent connection, as appropriate. - - For concreteness, this document will only refer to Internet - protocols. However, SIP MAY also be used directly with protocols - such as ATM AAL5, IPX, frame relay or X.25. The necessary naming - conventions are beyond the scope of this document. User agents SHOULD - implement both UDP and TCP transport. Proxy, registrar, and redirect - servers MUST implement both UDP and TCP transport. - -1.5.3 Text-Based - - SIP is text-based, using ISO 10646 in UTF-8 encoding throughout. This - allows easy implementation in languages such as Java, Tcl and Perl, - allows easy debugging, and most importantly, makes SIP flexible and - extensible. As SIP is used for initiating multimedia conferences - rather than delivering media data, it is believed that the additional - overhead of using a text-based protocol is not significant. - -2 SIP Uniform Resource Locators - - SIP URLs are used within SIP messages to indicate the originator - (From), current destination (Request-URI) and final recipient (To) of - a SIP request, and to specify redirection addresses (Contact). A SIP - URL can also be embedded in web pages or other hyperlinks to indicate - that a particular user or service can be called via SIP. When used as - a hyperlink, the SIP URL indicates the use of the INVITE method. - - The SIP URL scheme is defined to allow setting SIP request-header - fields and the SIP message-body. - - - This corresponds to the use of mailto: URLs. It makes it - possible, for example, to specify the subject, urgency or - media types of calls initiated through a web page or as - part of an email message. - - A SIP URL follows the guidelines of RFC 2396 [12] and has the syntax - shown in Fig. 3. The syntax is described using Augmented Backus-Naur - Form (See Section C). Note that reserved characters have to be - escaped and that the "set of characters reserved within any given URI - component is defined by that component. In general, a character is - reserved if the semantics of the URI changes if the character is - replaced with its escaped US-ASCII encoding" [12]. - - - - - -Handley, et al.

Standards Track [Page 22] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - port: The port number to send a request to. If not present, the - procedures outlined in Section 1.4.2 are used to determine the - port number to send a request to. - - URL parameters: SIP URLs can define specific parameters of the - request. URL parameters are added after the host component and - are separated by semi-colons. The transport parameter determines - the the transport mechanism (UDP or TCP). UDP is to be assumed - when no explicit transport parameter is included. The maddr - parameter provides the server address to be contacted for this - user, overriding the address supplied in the host field. This - address is typically a multicast address, but could also be the - address of a backup server. The ttl parameter determines the - time-to-live value of the UDP multicast packet and MUST only be - used if maddr is a multicast address and the transport protocol - is UDP. The user parameter was described above. For example, to - specify to call j.doe@big.com using multicast to 239.255.255.1 - with a ttl of 15, the following URL would be used: - - - sip:j.doe@big.com;maddr=239.255.255.1;ttl=15 - - - - The transport, maddr, and ttl parameters MUST NOT be used in the From - and To header fields and the Request-URI; they are ignored if - present. - - Headers: Headers of the SIP request can be defined with the "?" - mechanism within a SIP URL. The special hname "body" indicates - that the associated hvalue is the message-body of the SIP INVITE - request. Headers MUST NOT be used in the From and To header - fields and the Request-URI; they are ignored if present. hname - and hvalue are encodings of a SIP header name and value, - respectively. All URL reserved characters in the header names - and values MUST be escaped. - - Method: The method of the SIP request can be specified with the - method parameter. This parameter MUST NOT be used in the From - and To header fields and the Request-URI; they are ignored if - present. - - Table 2 summarizes where the components of the SIP URL can be used - and what default values they assume if not present. - - - Examples of SIP URLs are: - - - - -Handley, et al.

As an example, if a call - from a telephone is relayed to the Internet via SIP, the SIP From - header field might contain a phone URL. - -3 SIP Message Overview - - SIP is a text-based protocol and uses the ISO 10646 character set in - UTF-8 encoding (RFC 2279 [21]). Senders MUST terminate lines with a - CRLF, but receivers MUST also interpret CR and LF by themselves as - line terminators. - - - -Handley, et al. Standards Track [Page 24] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Except for the above difference in character sets, much of the - message syntax is and header fields are identical to HTTP/1.1; rather - than repeating the syntax and semantics here we use [HX.Y] to refer - to Section X.Y of the current HTTP/1.1 specification (RFC 2068 [11]). - In addition, we describe SIP in both prose and an augmented Backus- - Naur form (ABNF). See section C for an overview of ABNF. - - Note, however, that SIP is not an extension of HTTP. - - Unlike HTTP, SIP MAY use UDP. When sent over TCP or UDP, multiple SIP - transactions can be carried in a single TCP connection or UDP - datagram. UDP datagrams, including all headers, SHOULD NOT be larger - than the path maximum transmission unit (MTU) if the MTU is known, or - 1500 bytes if the MTU is unknown. - - - The 1500 bytes accommodates encapsulation within the - "typical" ethernet MTU without IP fragmentation.

The message body contains a description - of the session to which the callee is being invited. For two-party - calls, the caller indicates the type of media it is able to receive - and possibly the media it is willing to send as well as their - parameters such as network destination. A success response MUST - indicate in its message body which media the callee wishes to receive - and MAY indicate the media the callee is going to send. - - - Not all session description formats have the ability to - indicate sending media. - - A server MAY automatically respond to an invitation for a conference - the user is already participating in, identified either by the SIP - Call-ID or a globally unique identifier within the session - description, with a 200 (OK) response. - - If a user agent receives an INVITE request for an existing call leg - with a higher CSeq sequence number than any previous INVITE for the - same Call-ID, it MUST check any version identifiers in the session - description or, if there are no version identifiers, the content of - the session description to see if it has changed. It MUST also - inspect any other header fields for changes. If there is a change, - the user agent MUST update any internal state or information - generated as a result of that header. If the session description has - changed, the user agent server MUST adjust the session parameters - accordingly, possibly after asking the user for confirmation. - (Versioning of the session description can be used to accommodate the - capabilities of new arrivals to a conference, add or delete media or - change from a unicast to a multicast conference.) - - This method MUST be supported by SIP proxy, redirect and user agent - servers as well as clients. - - - - - -Handley, et al. Standards Track [Page 28] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -4.2.2 ACK - - The ACK request confirms that the client has received a final - response to an INVITE request. (ACK is used only with INVITE - requests.) 2xx responses are acknowledged by client user agents, all - other final responses by the first proxy or client user agent to - receive the response. The Via is always initialized to the host that - originates the ACK request, i.e., the client user agent after a 2xx - response or the first proxy to receive a non-2xx final response. The - ACK request is forwarded as the corresponding INVITE request, based - on its Request-URI. See Section 10 for details. - - The ACK request MAY contain a message body with the final session - description to be used by the callee. If the ACK message body is - empty, the callee uses the session description in the INVITE request. - - A proxy server receiving an ACK request after having sent a 3xx, 4xx, - 5xx, or 6xx response must make a determination about whether the ACK - is for it, or for some user agent or proxy server further downstream. - This determination is made by examining the tag in the To field. If - the tag in the ACK To header field matches the tag in the To header - field of the response, and the From, CSeq and Call-ID header fields - in the response match those in the ACK, the ACK is meant for the - proxy server. Otherwise, the ACK SHOULD be proxied downstream as any - other request. - - - It is possible for a user agent client or proxy server to - receive multiple 3xx, 4xx, 5xx, and 6xx responses to a - request along a single branch. This can happen under - various error conditions, typically when a forking proxy - transitions from stateful to stateless before receiving all - responses. The various responses will all be identical, - except for the tag in the To field, which is different for - each one. It can therefore be used as a means to - disambiguate them. - - This method MUST be supported by SIP proxy, redirect and user agent - servers as well as clients. - -4.2.3 OPTIONS - - The server is being queried as to its capabilities. A server that - believes it can contact the user, such as a user agent where the user - is logged in and has been recently active, MAY respond to this - request with a capability set. A called user agent MAY return a - status reflecting how it would have responded to an invitation, e.g., - - - - -Handley, et al. Standards Track [Page 29] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - 600 (Busy). Such a server SHOULD return an Allow header field - indicating the methods that it supports. Proxy and redirect servers - simply forward the request without indicating their capabilities. - - This method MUST be supported by SIP proxy, redirect and user agent - servers, registrars and clients. - -4.2.4 BYE - - The user agent client uses BYE to indicate to the server that it - wishes to release the call. A BYE request is forwarded like an INVITE - request and MAY be issued by either caller or callee. A party to a - call SHOULD issue a BYE request before releasing a call ("hanging - up"). A party receiving a BYE request MUST cease transmitting media - streams specifically directed at the party issuing the BYE request. - - If the INVITE request contained a Contact header, the callee SHOULD - send a BYE request to that address rather than the From address. - - This method MUST be supported by proxy servers and SHOULD be - supported by redirect and user agent SIP servers. - -4.2.5 CANCEL - - The CANCEL request cancels a pending request with the same Call-ID, - To, From and CSeq (sequence number only) header field values, but - does not affect a completed request. (A request is considered - completed if the server has returned a final status response.) - - A user agent client or proxy client MAY issue a CANCEL request at any - time. A proxy, in particular, MAY choose to send a CANCEL to - destinations that have not yet returned a final response after it has - received a 2xx or 6xx response for one or more of the parallel-search - requests. A proxy that receives a CANCEL request forwards the request - to all destinations with pending requests. - - The Call-ID, To, the numeric part of CSeq and From headers in the - CANCEL request are identical to those in the original request. This - allows a CANCEL request to be matched with the request it cancels. - However, to allow the client to distinguish responses to the CANCEL - from those to the original request, the CSeq Method component is set - to CANCEL. The Via header field is initialized to the proxy issuing - the CANCEL request. (Thus, responses to this CANCEL request only - reach the issuing proxy.) - - Once a user agent server has received a CANCEL, it MUST NOT issue a - 2xx response for the cancelled original request. - - - - -Handley, et al. Standards Track [Page 30] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - A redirect or user agent server receiving a CANCEL request responds - with a status of 200 (OK) if the transaction exists and a status of - 481 (Transaction Does Not Exist) if not, but takes no further action. - In particular, any existing call is unaffected. - - - The BYE request cannot be used to cancel branches of a - parallel search, since several branches may, through - intermediate proxies, find the same user agent server and - then terminate the call. To terminate a call instead of - just pending searches, the UAC must use BYE instead of or - in addition to CANCEL. While CANCEL can terminate any - pending request other than ACK or CANCEL, it is typically - useful only for INVITE. 200 responses to INVITE and 200 - responses to CANCEL are distinguished by the method in the - Cseq header field, so there is no ambiguity. - - This method MUST be supported by proxy servers and SHOULD be - supported by all other SIP server types. - -4.2.6 REGISTER - - A client uses the REGISTER method to register the address listed in - the To header field with a SIP server. - - A user agent MAY register with a local server on startup by sending a - REGISTER request to the well-known "all SIP servers" multicast - address "sip.mcast.net" (224.0.1.75). This request SHOULD be scoped - to ensure it is not forwarded beyond the boundaries of the - administrative system. This MAY be done with either TTL or - administrative scopes [25], depending on what is implemented in the - network. SIP user agents MAY listen to that address and use it to - become aware of the location of other local users [20]; however, they - do not respond to the request. A user agent MAY also be configured - with the address of a registrar server to which it sends a REGISTER - request upon startup. - - Requests are processed in the order received. Clients SHOULD avoid - sending a new registration (as opposed to a retransmission) until - they have received the response from the server for the previous one. - - - Clients may register from different locations, by necessity - using different Call-ID values. Thus, the CSeq value cannot - be used to enforce ordering. Since registrations are - additive, ordering is less of a problem than if each - REGISTER request completely replaced all earlier ones. - - - - -Handley, et al. Standards Track [Page 31] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - The meaning of the REGISTER request-header fields is defined as - follows. We define "address-of-record" as the SIP address that the - registry knows the registrand, typically of the form "user@domain" - rather than "user@host". In third-party registration, the entity - issuing the request is different from the entity being registered. - - To: The To header field contains the address-of-record whose - registration is to be created or updated. - - From: The From header field contains the address-of-record of the - person responsible for the registration. For first-party - registration, it is identical to the To header field value. - - Request-URI: The Request-URI names the destination of the - registration request, i.e., the domain of the registrar. The - user name MUST be empty. Generally, the domains in the Request- - URI and the To header field have the same value; however, it is - possible to register as a "visitor", while maintaining one's - name. For example, a traveler sip:alice@acme.com (To) might - register under the Request-URI sip:atlanta.hiayh.org , with the - former as the To header field and the latter as the Request-URI. - The REGISTER request is no longer forwarded once it has reached - the server whose authoritative domain is the one listed in the - Request-URI. - - Call-ID: All registrations from a client SHOULD use the same Call-ID - header value, at least within the same reboot cycle. - - Cseq: Registrations with the same Call-ID MUST have increasing CSeq - header values. However, the server does not reject out-of-order - requests. - - Contact: The request MAY contain a Contact header field; future non- - REGISTER requests for the URI given in the To header field - SHOULD be directed to the address(es) given in the Contact - header. - - If the request does not contain a Contact header, the registration - remains unchanged. - - This is useful to obtain the current list of registrations - in the response. Registrations using SIP URIs that differ - in one or more of host, port, transport-param or maddr- - param (see Figure 3) from an existing registration are - added to the list of registrations. Other URI types are - compared according to the standard URI equivalency rules - for the URI schema. If the URIs are equivalent to that of - an existing registration, the new registration replaces the - - - -Handley, et al. Standards Track [Page 32] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - old one if it has a higher q value or, for the same value - of q, if the ttl value is higher. All current registrations - MUST share the same action value. Registrations that have - a different action than current registrations for the same - user MUST be rejected with status of 409 (Conflict). - - A proxy server ignores the q parameter when processing non-REGISTER - requests, while a redirect server simply returns that parameter in - its Contact response header field. - - - Having the proxy server interpret the q parameter is not - sufficient to guide proxy behavior, as it is not clear, for - example, how long it is supposed to wait between trying - addresses. - - If the registration is changed while a user agent or proxy server - processes an invitation, the new information SHOULD be used. - - - This allows a service known as "directed pick-up". In the - telephone network, directed pickup permits a user at a - remote station who hears his own phone ringing to pick up - at that station, dial an access code, and be connected to - the calling user as if he had answered his own phone. - - A server MAY choose any duration for the registration lifetime. - Registrations not refreshed after this amount of time SHOULD be - silently discarded. Responses to a registration SHOULD include an - Expires header (Section 6.20) or expires Contact parameters (Section - 6.13), indicating the time at which the server will drop the - registration. If none is present, one hour is assumed. Clients MAY - request a registration lifetime by indicating the time in an Expires - header in the request. A server SHOULD NOT use a higher lifetime than - the one requested, but MAY use a lower one. A single address (if - host-independent) MAY be registered from several different clients. - - A client cancels an existing registration by sending a REGISTER - request with an expiration time (Expires) of zero seconds for a - particular Contact or the wildcard Contact designated by a "*" for - all registrations. Registrations are matched based on the user, host, - port and maddr parameters. - - The server SHOULD return the current list of registrations in the 200 - response as Contact header fields. - - It is particularly important that REGISTER requests are authenticated - since they allow to redirect future requests (see Section 13.2). - - - -Handley, et al. Standards Track [Page 33] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Beyond its use as a simple location service, this method is - needed if there are several SIP servers on a single host. - In that case, only one of the servers can use the default - port number. - - - Support of this method is RECOMMENDED. - -4.3 Request-URI - - The Request-URI is a SIP URL as described in Section 2 or a general - URI. It indicates the user or service to which this request is being - addressed. Unlike the To field, the Request-URI MAY be re-written by - proxies. - - When used as a Request-URI, a SIP-URL MUST NOT contain the - transport-param, maddr-param, ttl-param, or headers elements. A - server that receives a SIP-URL with these elements removes them - before further processing. - - - Typically, the UAC sets the Request-URI and To to the same - SIP URL, presumed to remain unchanged over long time - periods. However, if the UAC has cached a more direct path - to the callee, e.g., from the Contact header field of a - response to a previous request, the To would still contain - the long-term, "public" address, while the Request-URI - would be set to the cached address. - - Proxy and redirect servers MAY use the information in the Request-URI - and request header fields to handle the request and possibly rewrite - the Request-URI. For example, a request addressed to the generic - address sip:sales@acme.com is proxied to the particular person, e.g., - sip:bob@ny.acme.com , with the To field remaining as - sip:sales@acme.com. At ny.acme.com , Bob then designates Alice as - the temporary substitute. - - The host part of the Request-URI typically agrees with one of the - host names of the receiving server. If it does not, the server SHOULD - proxy the request to the address indicated or return a 404 (Not - Found) response if it is unwilling or unable to do so. For example, - the Request-URI and server host name can disagree in the case of a - firewall proxy that handles outgoing calls. This mode of operation is - similar to that of HTTP proxies. - - If a SIP server receives a request with a URI indicating a scheme - other than SIP which that server does not understand, the server MUST - return a 400 (Bad Request) response. It MUST do this even if the To - - - -Handley, et al. Standards Track [Page 34] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - header field contains a scheme it does understand. This is because - proxies are responsible for processing the Request-URI; the To field - is of end-to-end significance. - -4.3.1 SIP Version - - Both request and response messages include the version of SIP in use, - and follow [H3.1] (with HTTP replaced by SIP, and HTTP/1.1 replaced - by SIP/2.0) regarding version ordering, compliance requirements, and - upgrading of version numbers. To be compliant with this - specification, applications sending SIP messages MUST include a SIP- - Version of "SIP/2.0". - -4.4 Option Tags - - Option tags are unique identifiers used to designate new options in - SIP. These tags are used in Require (Section 6.30) and Unsupported - (Section 6.38) fields. - - Syntax: - - - option-tag = token - - - See Section C for a definition of token. The creator of a new SIP - option MUST either prefix the option with their reverse domain name - or register the new option with the Internet Assigned Numbers - Authority (IANA). For example, "com.foo.mynewfeature" is an apt name - for a feature whose inventor can be reached at "foo.com". Individual - organizations are then responsible for ensuring that option names - don't collide. Options registered with IANA have the prefix - "org.iana.sip.", options described in RFCs have the prefix - "org.ietf.rfc.N", where N is the RFC number. Option tags are case- - insensitive. - -4.4.1 Registering New Option Tags with IANA - - When registering a new SIP option, the following information MUST be - provided: - - o Name and description of option. The name MAY be of any - length, but SHOULD be no more than twenty characters long. The - name MUST consist of alphanum (See Figure 3) characters only; - - - - - - - -Handley, et al.

SIP applications are not required - to understand the meaning of all registered response codes, though - such understanding is obviously desirable. However, applications MUST - understand the class of any response code, as indicated by the first - digit, and treat any unrecognized response as being equivalent to the - x00 response code of that class, with the exception that an - unrecognized response MUST NOT be cached. For example, if a client - receives an unrecognized response code of 431, it can safely assume - that there was something wrong with its request and treat the - response as if it had received a 400 (Bad Request) response code.

Proxies SHOULD NOT reorder - header fields. Proxies add Via header fields and MAY add other hop- - by-hop header fields. They can modify certain header fields, such as - Max-Forwards (Section 6.23) and "fix up" the Via header fields with - "received" parameters as described in Section 6.40.1. Proxies MUST - NOT alter any fields that are authenticated (see Section 13.2). - - The header fields required, optional and not applicable for each - method are listed in Table 4 and Table 5. The table uses "o" to - indicate optional, "m" mandatory and "-" for not applicable. A "*" - indicates that the header fields are needed only if message body is - not empty. See sections 6.15, 6.16 and 8 for details. - - The "where" column describes the request and response types with - which the header field can be used. "R" refers to header fields that - can be used in requests (that is, request and general header fields). - "r" designates a response or general-header field as applicable to - all responses, while a list of numeric values indicates the status - codes with which the header field can be used.

Each header field consists of a - name followed by a colon (":") and the field value. Field names are - case-insensitive. The field value MAY be preceded by any amount of - leading white space (LWS), though a single space (SP) is preferred. - Header fields can be extended over multiple lines by preceding each - extra line with at least one SP or horizontal tab (HT). Applications - MUST follow HTTP "common form" when generating these constructs, - since there might exist some implementations that fail to accept - anything beyond the common forms. - - - - -Handley, et al.

Multiple header fields with the same field-name may be - present in a message if and only if the entire field-value for that - header field is defined as a comma-separated list (i.e., #(values)). - It MUST be possible to combine the multiple header fields into one - "field-name: field-value" pair, without changing the semantics of the - message, by appending each subsequent field-value to the first, each - separated by a comma. The order in which header fields with the same - field-name are received is therefore significant to the - interpretation of the combined field value, and thus a proxy MUST NOT - change the order of these field values when a message is forwarded. - - Field names are not case-sensitive, although their values may be. - -6.7 Accept - - The Accept header follows the syntax defined in [H14.1]. The - semantics are also identical, with the exception that if no Accept - header is present, the server SHOULD assume a default value of - application/sdp. - - This request-header field is used only with the INVITE, OPTIONS and - REGISTER request methods to indicate what media types are acceptable - in the response. - - Example: - - - Accept: application/sdp;level=1, application/x-private, text/html - - - -6.8 Accept-Encoding - - The Accept-Encoding request-header field is similar to Accept, but - restricts the content-codings [H3.4.1] that are acceptable in the - response. See [H14.3]. The syntax of this header is defined in - [H14.3]. The semantics in SIP are identical to those defined in - [H14.3]. - - - -Handley, et al.

The - rules for ordering the languages based on the q parameter apply to - SIP as well. When used in SIP, the Accept-Language request-header - field can be used to allow the client to indicate to the server in - which language it would prefer to receive reason phrases, session - descriptions or status responses carried as message bodies. A proxy - MAY use this field to help select the destination for the call, for - example, a human operator conversant in a language spoken by the - caller. - - Example: - - - Accept-Language: da, en-gb;q=0.8, en;q=0.7 - - -6.10 Allow - - The Allow entity-header field lists the set of methods supported by - the resource identified by the Request-URI. The purpose of this field - is strictly to inform the recipient of valid methods associated with - the resource.

The Authorization field value consists of credentials - containing the authentication information of the user agent for the - realm of the resource being requested. - - Section 13.2 overviews the use of the Authorization header, and - section 15 describes the syntax and semantics when used with PGP - based authentication. - - - - - - - - -Handley, et al. Standards Track [Page 45] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -6.12 Call-ID - - The Call-ID general-header field uniquely identifies a particular - invitation or all registrations of a particular client. Note that a - single multimedia conference can give rise to several calls with - different Call-IDs, e.g., if a user invites a single individual - several times to the same (long-running) conference. - - For an INVITE request, a callee user agent server SHOULD NOT alert - the user if the user has responded previously to the Call-ID in the - INVITE request. If the user is already a member of the conference and - the conference parameters contained in the session description have - not changed, a callee user agent server MAY silently accept the call, - regardless of the Call-ID. An invitation for an existing Call-ID or - session can change the parameters of the conference. A client - application MAY decide to simply indicate to the user that the - conference parameters have been changed and accept the invitation - automatically or it MAY require user confirmation. - - A user may be invited to the same conference or call using several - different Call-IDs. If desired, the client MAY use identifiers within - the session description to detect this duplication. For example, SDP - contains a session id and version number in the origin (o) field. - - The REGISTER and OPTIONS methods use the Call-ID value to - unambiguously match requests and responses. All REGISTER requests - issued by a single client SHOULD use the same Call-ID, at least - within the same boot cycle. - - - Since the Call-ID is generated by and for SIP, there is no - reason to deal with the complexity of URL-encoding and - case-ignoring string comparison. - - - - Call-ID = ( "Call-ID" | "i" ) ":" local-id "@" host - local-id = 1*uric - - - "host" SHOULD be either a fully qualified domain name or a globally - routable IP address. If this is the case, the "local-id" SHOULD be an - identifier consisting of URI characters that is unique within "host". - Use of cryptographically random identifiers [27] is RECOMMENDED. If, - however, host is not an FQDN or globally routable IP address (such as - a net 10 address), the local-id MUST be globally unique, as opposed - - - - - -Handley, et al. Standards Track [Page 46] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - to unique within host. These rules guarantee overall global - uniqueness of the Call-ID. The value for Call-ID MUST NOT be reused - for a different call. Call-IDs are case-sensitive. - - - Using cryptographically random identifiers provides some - protection against session hijacking. Call-ID, To and From - are needed to identify a call leg. The distinction between - call and call leg matters in calls with third-party - control. - - For systems which have tight bandwidth constraints, many of the - mandatory SIP headers have a compact form, as discussed in Section 9. - These are alternate names for the headers which occupy less space in - the message. In the case of Call-ID, the compact form is i. - - For example, both of the following are valid: - - Call-ID: f81d4fae-7dec-11d0-a765-00a0c91e6bf6@foo.bar.com - - - or - - i:f81d4fae-7dec-11d0-a765-00a0c91e6bf6@foo.bar.com - - - -6.13 Contact - - The Contact general-header field can appear in INVITE, ACK, and - REGISTER requests, and in 1xx, 2xx, 3xx, and 485 responses. In - general, it provides a URL where the user can be reached for further - communications. - - INVITE and ACK requests: INVITE and ACK requests MAY contain Contact - headers indicating from which location the request is - originating. - - - This allows the callee to send future requests, such as - BYE, directly to the caller instead of through a series of - proxies. The Via header is not sufficient since the - desired address may be that of a proxy. - - INVITE 2xx responses: A user agent server sending a definitive, - positive response (2xx) MAY insert a Contact response header - field indicating the SIP address under which it is reachable - most directly for future SIP requests, such as ACK, within the - - - -Handley, et al. Standards Track [Page 47] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - same Call-ID. The Contact header field contains the address of - the server itself or that of a proxy, e.g., if the host is - behind a firewall. The value of this Contact header is copied - into the Request-URI of subsequent requests for this call if the - response did not also contain a Record-Route header. If the - response also contains a Record-Route header field, the address - in the Contact header field is added as the last item in the - Route header field. See Section 6.29 for details. - - - The Contact value SHOULD NOT be cached across calls, as it - may not represent the most desirable location for a - particular destination address. - - INVITE 1xx responses: A UAS sending a provisional response (1xx) MAY - insert a Contact response header. It has the same semantics in a - 1xx response as a 2xx INVITE response. Note that CANCEL requests - MUST NOT be sent to that address, but rather follow the same - path as the original request. - - REGISTER requests: REGISTER requests MAY contain a Contact header - field indicating at which locations the user is reachable. The - REGISTER request defines a wildcard Contact field, "*", which - MUST only be used with Expires: 0 to remove all registrations - for a particular user. An optional "expires" parameter indicates - the desired expiration time of the registration. If a Contact - entry does not have an "expires" parameter, the Expires header - field is used as the default value. If neither of these - mechanisms is used, SIP URIs are assumed to expire after one - hour. Other URI schemes have no expiration times. - - REGISTER 2xx responses: A REGISTER response MAY return all locations - at which the user is currently reachable. An optional "expires" - parameter indicates the expiration time of the registration. If - a Contact entry does not have an "expires" parameter, the value - of the Expires header field indicates the expiration time. If - neither mechanism is used, the expiration time specified in the - request, explicitly or by default, is used. - - 3xx and 485 responses: The Contact response-header field can be used - with a 3xx or 485 (Ambiguous) response codes to indicate one or - more alternate addresses to try. It can appear in responses to - BYE, INVITE and OPTIONS methods. The Contact header field - contains URIs giving the new locations or user names to try, or - may simply specify additional transport parameters. A 300 - (Multiple Choices), 301 (Moved Permanently), 302 (Moved - Temporarily) or 485 (Ambiguous) response SHOULD contain a - Contact field containing URIs of new addresses to be tried. A - - - -Handley, et al. Standards Track [Page 48] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - 301 or 302 response may also give the same location and username - that was being tried but specify additional transport parameters - such as a different server or multicast address to try or a - change of SIP transport from UDP to TCP or vice versa. The - client copies the "user", "password", "host", "port" and "user- - param" elements of the Contact URI into the Request-URI of the - redirected request and directs the request to the address - specified by the "maddr" and "port" parameters, using the - transport protocol given in the "transport" parameter. If - "maddr" is a multicast address, the value of "ttl" is used as - the time-to-live value. - - Note that the Contact header field MAY also refer to a different - entity than the one originally called. For example, a SIP call - connected to GSTN gateway may need to deliver a special information - announcement such as "The number you have dialed has been changed." - - A Contact response header field can contain any suitable URI - indicating where the called party can be reached, not limited to SIP - URLs. For example, it could contain URL's for phones, fax, or irc (if - they were defined) or a mailto: (RFC 2368, [28]) URL. - - The following parameters are defined. Additional parameters may be - defined in other specifications. - - q: The "qvalue" indicates the relative preference among the locations - given. "qvalue" values are decimal numbers from 0 to 1, with - higher values indicating higher preference. - - action: The "action" parameter is used only when registering with the - REGISTER request. It indicates whether the client wishes that - the server proxy or redirect future requests intended for the - client. If this parameter is not specified the action taken - depends on server configuration. In its response, the registrar - SHOULD indicate the mode used. This parameter is ignored for - other requests. - - expires: The "expires" parameter indicates how long the URI is valid. - The parameter is either a number indicating seconds or a quoted - string containing a SIP-date. If this parameter is not provided, - the value of the Expires header field determines how long the - URI is valid. Implementations MAY treat values larger than - 2**32-1 (4294967295 seconds or 136 years) as equivalent to - 2**32-1. - - - - Contact = ( "Contact" | "m" ) ":" - ("*" | (1# (( name-addr | addr-spec ) - [ *( ";" contact-params ) ] [ comment ] ))) - - name-addr = [ display-name ] "<" addr-spec ">" - addr-spec = SIP-URL | URI - display-name = *token | quoted-string - - contact-params = "q" "=" qvalue - | "action" "=" "proxy" | "redirect" - | "expires" "=" delta-seconds | <"> SIP-date <"> - | extension-attribute - - extension-attribute = extension-name [ "=" extension-value ] - - only allows one address, unquoted. Since URIs can contain - commas and semicolons as reserved characters, they can be - mistaken for header or parameter delimiters, respectively. - The current syntax corresponds to that for the To and From - header, which also allows the use of display names. - - Example: - - - Contact: "Mr. Watson" - ;q=0.7; expires=3600, - "Mr. Watson" ;q=0.1 - - - -6.14 Content-Encoding - - - - Content-Encoding = ( "Content-Encoding" | "e" ) ":" - 1#content-coding - - - The Content-Encoding entity-header field is used as a modifier to the - "media-type". When present, its value indicates what additional - content codings have been applied to the entity-body, and thus what - decoding mechanisms MUST be applied in order to obtain the media-type - referenced by the Content-Type header field. Content-Encoding is - primarily used to allow a body to be compressed without losing the - identity of its underlying media type. - - If multiple encodings have been applied to an entity, the content - codings MUST be listed in the order in which they were applied. - - All content-coding values are case-insensitive. The Internet Assigned - Numbers Authority (IANA) acts as a registry for content-coding value - tokens. See [3.5] for a definition of the syntax for content-coding. - - Clients MAY apply content encodings to the body in requests. If the - server is not capable of decoding the body, or does not recognize any - of the content-coding values, it MUST send a 415 "Unsupported Media - Type" response, listing acceptable encodings in the Accept-Encoding - - - -Handley, et al. Standards Track [Page 50] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - header. A server MAY apply content encodings to the bodies in - responses. The server MUST only use encodings listed in the Accept- - Encoding header in the request. - -6.15 Content-Length - - The Content-Length entity-header field indicates the size of the - message-body, in decimal number of octets, sent to the recipient. - - - - Content-Length = ( "Content-Length" | "l" ) ":" 1*DIGIT - - - An example is - - Content-Length: 3495 - - - - Applications SHOULD use this field to indicate the size of the - message-body to be transferred, regardless of the media type of the - entity. Any Content-Length greater than or equal to zero is a valid - value. If no body is present in a message, then the Content-Length - header field MUST be set to zero. If a server receives a UDP request - without Content-Length, it MUST assume that the request encompasses - the remainder of the packet. If a server receives a UDP request with - a Content-Length, but the value is larger than the size of the body - sent in the request, the client SHOULD generate a 400 class response. - If there is additional data in the UDP packet after the last byte of - the body has been read, the server MUST treat the remaining data as a - separate message. This allows several messages to be placed in a - single UDP packet. - - If a response does not contain a Content-Length, the client assumes - that it encompasses the remainder of the UDP packet or the data until - the TCP connection is closed, as applicable. Section 8 describes how - to determine the length of the message body. - -6.16 Content-Type - - The Content-Type entity-header field indicates the media type of the - message-body sent to the recipient.

A CSeq header field in a request contains the request - method and a single decimal sequence number chosen by the requesting - client, unique within a single value of Call-ID. The sequence number - MUST be expressible as a 32-bit unsigned integer. The initial value - of the sequence number is arbitrary, but MUST be less than 2**31. - Consecutive requests that differ in request method, headers or body, - but have the same Call-ID MUST contain strictly monotonically - increasing and contiguous sequence numbers; sequence numbers do not - wrap around. Retransmissions of the same request carry the same - sequence number, but an INVITE with a different message body or - different header fields (a "re-invitation") acquires a new, higher - sequence number. A server MUST echo the CSeq value from the request - in its response. If the Method value is missing in the received CSeq - header field, the server fills it in appropriately. - - The ACK and CANCEL requests MUST contain the same CSeq value as the - INVITE request that it refers to, while a BYE request cancelling an - invitation MUST have a higher sequence number. A BYE request with a - CSeq that is not higher should cause a 400 response to be generated. - - A user agent server MUST remember the highest sequence number for any - INVITE request with the same Call-ID value. The server MUST respond - to, and then discard, any INVITE request with a lower sequence - number. - - All requests spawned in a parallel search have the same CSeq value as - the request triggering the parallel search. - - - - CSeq = "CSeq" ":" 1*DIGIT Method - - - - Strictly speaking, CSeq header fields are needed for any - SIP request that can be cancelled by a BYE or CANCEL - request or where a client can issue several requests for - the same Call-ID in close succession. Without a sequence - - - -Handley, et al. Standards Track [Page 52] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - number, the response to an INVITE could be mistaken for the - response to the cancellation (BYE or CANCEL). Also, if the - network duplicates packets or if an ACK is delayed until - the server has sent an additional response, the client - could interpret an old response as the response to a re- - invitation issued shortly thereafter. Using CSeq also makes - it easy for the server to distinguish different versions of - an invitation, without comparing the message body. - - The Method value allows the client to distinguish the response to an - INVITE request from that of a CANCEL response. CANCEL requests can be - generated by proxies; if they were to increase the sequence number, - it might conflict with a later request issued by the user agent for - the same call. - - With a length of 32 bits, a server could generate, within a single - call, one request a second for about 136 years before needing to wrap - around. The initial value of the sequence number is chosen so that - subsequent requests within the same call will not wrap around. A - non-zero initial value allows to use a time-based initial sequence - number, if the client desires. A client could, for example, choose - the 31 most significant bits of a 32-bit second clock as an initial - sequence number. - - Forked requests MUST have the same CSeq as there would be ambiguity - otherwise between these forked requests and later BYE issued by the - client user agent. - - Example: - - - CSeq: 4711 INVITE - - - -6.18 Date - - Date is a general-header field. Its syntax is: - - - - SIP-date = rfc1123-date - - - See [H14.19] for a definition of rfc1123-date. Note that unlike - HTTP/1.1, SIP only supports the most recent RFC1123 [29] formatting - for dates. - - - - -Handley, et al. Standards Track [Page 53] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - The Date header field reflects the time when the request or response - is first sent. Thus, retransmissions have the same Date header field - value as the original. - - - The Date header field can be used by simple end systems - without a battery-backed clock to acquire a notion of - current time. - -6.19 Encryption - - The Encryption general-header field specifies that the content has - been encrypted. Section 13 describes the overall SIP security - architecture and algorithms. This header field is intended for end- - to-end encryption of requests and responses. Requests are encrypted - based on the public key belonging to the entity named in the To - header field. Responses are encrypted based on the public key - conveyed in the Response-Key header field. Note that the public keys - themselves may not be used for the encryption. This depends on the - particular algorithms used. - - For any encrypted message, at least the message body and possibly - other message header fields are encrypted. An application receiving a - request or response containing an Encryption header field decrypts - the body and then concatenates the plaintext to the request line and - headers of the original message. Message headers in the decrypted - part completely replace those with the same field name in the - plaintext part. (Note: If only the body of the message is to be - encrypted, the body has to be prefixed with CRLF to allow proper - concatenation.) Note that the request method and Request-URI cannot - be encrypted. - - - Encryption only provides privacy; the recipient has no - guarantee that the request or response came from the party - listed in the From message header, only that the sender - used the recipient's public key. However, proxies will not - be able to modify the request or response. - - - - Encryption = "Encryption" ":" encryption-scheme 1*SP - #encryption-params - encryption-scheme = token - encryption-params = token "=" ( token | quoted-string ) - - The token indicates the form of encryption used; it is - described in section 13. - - - -Handley, et al.

For REGISTER, it is a request and response-header - field. In a REGISTER request, the client indicates how long it wishes - the registration to be valid. In the response, the server indicates - - - -Handley, et al. Standards Track [Page 55] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - the earliest expiration time of all registrations. The server MAY - choose a shorter time interval than that requested by the client, but - SHOULD NOT choose a longer one. - - For INVITE requests, it is a request and response-header field. In a - request, the caller can limit the validity of an invitation, for - example, if a client wants to limit the time duration of a search or - a conference invitation. A user interface MAY take this as a hint to - leave the invitation window on the screen even if the user is not - currently at the workstation. This also limits the duration of a - search. If the request expires before the search completes, the proxy - returns a 408 (Request Timeout) status. In a 302 (Moved Temporarily) - response, a server can advise the client of the maximal duration of - the redirection. - - The value of this field can be either a SIP-date or an integer number - of seconds (in decimal), measured from the receipt of the request. - The latter approach is preferable for short durations, as it does not - depend on clients and servers sharing a synchronized clock. - Implementations MAY treat values larger than 2**32-1 (4294967295 or - 136 years) as equivalent to 2**32-1. - - - - Expires = "Expires" ":" ( SIP-date | delta-seconds ) - - - Two examples of its use are - - Expires: Thu, 01 Dec 1994 16:00:00 GMT - Expires: 5 - - - -6.21 From - - Requests and responses MUST contain a From general-header field, - indicating the initiator of the request.

A single user maintains the same - tag throughout the call identified by the Call-ID. - - - Call-ID, To and From are needed to identify a call leg. - The distinction between call and call leg matters in calls - with multiple responses to a forked request. The format is - similar to the equivalent RFC 822 [24] header, but with a - URI instead of just an email address. - -6.22 Hide - - A client uses the Hide request header field to indicate that it wants - the path comprised of the Via header fields (Section 6.40) to be - hidden from subsequent proxies and user agents. It can take two - forms: Hide: route and Hide: hop. Hide header fields are typically - added by the client user agent, but MAY be added by any proxy along - the path. - - - - - - -Handley, et al. Standards Track [Page 57] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - If a request contains the "Hide: route" header field, all following - proxies SHOULD hide their previous hop. If a request contains the - "Hide: hop" header field, only the next proxy SHOULD hide the - previous hop and then remove the Hide option unless it also wants to - remain anonymous. - - A server hides the previous hop by encrypting the "host" and "port" - parts of the top-most Via header field with an algorithm of its - choice. Servers SHOULD add additional "salt" to the "host" and "port" - information prior to encryption to prevent malicious downstream - proxies from guessing earlier parts of the path based on seeing - identical encrypted Via headers. Hidden Via fields are marked with - the "hidden" Via option, as described in Section 6.40. - - A server that is capable of hiding Via headers MUST attempt to - decrypt all Via headers marked as "hidden" to perform loop detection. - Servers that are not capable of hiding can ignore hidden Via fields - in their loop detection algorithm. - - - If hidden headers were not marked, a proxy would have to - decrypt all headers to detect loops, just in case one was - encrypted, as the Hide: Hop option may have been removed - along the way. - - A host MUST NOT add such a "Hide: hop" header field unless it can - guarantee it will only send a request for this destination to the - same next hop. The reason for this is that it is possible that the - request will loop back through this same hop from a downstream proxy. - The loop will be detected by the next hop if the choice of next hop - is fixed, but could loop an arbitrary number of times otherwise. - - A client requesting "Hide: route" can only rely on keeping the - request path private if it sends the request to a trusted proxy. - Hiding the route of a SIP request is of limited value if the request - results in data packets being exchanged directly between the calling - and called user agent. - - The use of Hide header fields is discouraged unless path privacy is - truly needed; Hide fields impose extra processing costs and - restrictions for proxies and can cause requests to generate 482 (Loop - Detected) responses that could otherwise be avoided. - - The encryption of Via header fields is described in more detail in - Section 13. - - The Hide header field has the following syntax: - - - - -Handley, et al. Standards Track [Page 58] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Hide = "Hide" ":" ( "route" | "hop" ) - - -6.23 Max-Forwards - - The Max-Forwards request-header field may be used with any SIP method - to limit the number of proxies or gateways that can forward the - request to the next downstream server. This can also be useful when - the client is attempting to trace a request chain which appears to be - failing or looping in mid-chain. - - - - Max-Forwards = "Max-Forwards" ":" 1*DIGIT - - - The Max-Forwards value is a decimal integer indicating the remaining - number of times this request message is allowed to be forwarded. - - Each proxy or gateway recipient of a request containing a Max- - Forwards header field MUST check and update its value prior to - forwarding the request. If the received value is zero (0), the - recipient MUST NOT forward the request. Instead, for the OPTIONS and - REGISTER methods, it MUST respond as the final recipient. For all - other methods, the server returns 483 (Too many hops). - - If the received Max-Forwards value is greater than zero, then the - forwarded message MUST contain an updated Max-Forwards field with a - value decremented by one (1). - - Example: - - Max-Forwards: 6 - - - -6.24 Organization - - The Organization general-header field conveys the name of the - organization to which the entity issuing the request or response - belongs.

The field value - consists of a challenge that indicates the authentication scheme and - parameters applicable to the proxy for this Request-URI. - - Unlike its usage within HTTP, the Proxy-Authenticate header MUST be - passed upstream in the response to the UAC. In SIP, only UAC's can - authenticate themselves to proxies. - - The syntax for this header is defined in [H14.33]. See 14 for further - details on its usage. - - - - - -Handley, et al. Standards Track [Page 60] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - A client SHOULD cache the credentials used for a particular proxy - server and realm for the next request to that server. Credentials - are, in general, valid for a specific value of the Request-URI at a - particular proxy server. If a client contacts a proxy server that has - required authentication in the past, but the client does not have - credentials for the particular Request-URI, it MAY attempt to use the - most-recently used credential. The server responds with 401 - (Unauthorized) if the client guessed wrong. - - - This suggested caching behavior is motivated by proxies - restricting phone calls to authenticated users. It seems - likely that in most cases, all destinations require the - same password. Note that end-to-end authentication is - likely to be destination-specific. - -6.27 Proxy-Authorization - - The Proxy-Authorization request-header field allows the client to - identify itself (or its user) to a proxy which requires - authentication. The Proxy-Authorization field value consists of - credentials containing the authentication information of the user - agent for the proxy and/or realm of the resource being requested. - - Unlike Authorization, the Proxy-Authorization header field applies - only to the next outbound proxy that demanded authentication using - the Proxy- Authenticate field. When multiple proxies are used in a - chain, the Proxy-Authorization header field is consumed by the first - outbound proxy that was expecting to receive credentials. A proxy MAY - relay the credentials from the client request to the next proxy if - that is the mechanism by which the proxies cooperatively authenticate - a given request. - - See [H14.34] for a definition of the syntax, and section 14 for a - discussion of its usage. - -6.28 Proxy-Require - - The Proxy-Require header field is used to indicate proxy-sensitive - features that MUST be supported by the proxy. Any Proxy-Require - header field features that are not supported by the proxy MUST be - negatively acknowledged by the proxy to the client if not supported. - Proxy servers treat this field identically to the Require field. - - See Section 6.30 for more details on the mechanics of this message - and a usage example. - - - - - -Handley, et al. Standards Track [Page 61] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -6.29 Record-Route - - The Record-Route request and response header field is added to a - request by any proxy that insists on being in the path of subsequent - requests for the same call leg. It contains a globally reachable - Request-URI that identifies the proxy server. Each proxy server adds - its Request-URI to the beginning of the list. - - The server copies the Record-Route header field unchanged into the - response. (Record-Route is only relevant for 2xx responses.) - - The calling user agent client copies the Record-Route header into a - Route header field of subsequent requests within the same call leg, - reversing the order of requests, so that the first entry is closest - to the user agent client. If the response contained a Contact header - field, the calling user agent adds its content as the last Route - header. Unless this would cause a loop, any client MUST send any - subsequent requests for this call leg to the first Request-URI in the - Route request header field and remove that entry. - - The calling user agent MUST NOT use the Record-Route header field in - requests that contain Route header fields. - - - Some proxies, such as those controlling firewalls or in an - automatic call distribution (ACD) system, need to maintain - call state and thus need to receive any BYE and ACK packets - for the call. - - The Record-Route header field has the following syntax: - - - Record-Route = "Record-Route" ":" 1# name-addr - - - Proxy servers SHOULD use the "maddr" URL parameter containing their - address to ensure that subsequent requests are guaranteed to reach - exactly the same server. - - Example for a request that has traversed the hosts ieee.org and - bell-telephone.com , in that order: - - Record-Route: , - - - - - - - - -Handley, et al.

In addition, it also removes ambiguity when the - client requires features that the server does not - understand. Some features, such as call handling fields, - are only of interest to end systems. - - Proxy and redirect servers MUST ignore features that are not - understood. If a particular extension requires that intermediate - devices support it, the extension MUST be tagged in the Proxy-Require - field as well (see Section 6.28). - -6.31 Response-Key - - The Response-Key request-header field can be used by a client to - request the key that the called user agent SHOULD use to encrypt the - response with. The syntax is: - - - - - -Handley, et al.

Section 13 describes security schemes. - - If the client insists that the server return an encrypted response, - it includes a - - Require: org.ietf.sip.encrypt-response - - header field in its request. If the server cannot encrypt for - whatever reason, it MUST follow normal Require header field - procedures and return a 420 (Bad Extension) response. If this Require - header field is not present, a server SHOULD still encrypt if it can. - -6.32 Retry-After - - The Retry-After general-header field can be used with a 503 (Service - Unavailable) response to indicate how long the service is expected to - be unavailable to the requesting client and with a 404 (Not Found), - 600 (Busy), or 603 (Decline) response to indicate when the called - party anticipates being available again. The value of this field can - be either an SIP-date or an integer number of seconds (in decimal) - after the time of the response. - - A REGISTER request MAY include this header field when deleting - registrations with "Contact: * ;expires: 0". The Retry-After value - then indicates when the user might again be reachable. The registrar - MAY then include this information in responses to future calls. - - An optional comment can be used to indicate additional information - about the time of callback. An optional "duration" parameter - indicates how long the called party will be reachable starting at the - initial time of availability.

Standards Track [Page 66] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - The "tag" parameter serves as a general mechanism to distinguish - multiple instances of a user identified by a single SIP URL. As - proxies can fork requests, the same request can reach multiple - instances of a user (mobile and home phones, for example). As each - can respond, there needs to be a means to distinguish the responses - from each at the caller. The situation also arises with multicast - requests. The tag in the To header field serves to distinguish - responses at the UAC. It MUST be placed in the To field of the - response by each instance when there is a possibility that the - request was forked at an intermediate proxy. The "tag" MUST be added - by UAS, registrars and redirect servers, but MUST NOT be inserted - into responses forwarded upstream by proxies. The "tag" is added for - all definitive responses for all methods, and MAY be added for - informational responses from a UAS or redirect server. All subsequent - transactions between two entities MUST include the "tag" parameter, - as described in Section 11. - - See Section 6.21 for details of the "tag" parameter. - - The "tag" parameter in To headers is ignored when matching responses - to requests that did not contain a "tag" in their To header. - - A SIP server returns a 400 (Bad Request) response if it receives a - request with a To header field containing a URI with a scheme it does - not recognize. - - Even if the "display-name" is empty, the "name-addr" form MUST be - used if the "addr-spec" contains a comma, question mark, or - semicolon. - - The following are examples of valid To headers: - - To: The Operator ;tag=287447 - To: sip:+12125551212@server.phone2net.com - - - - - Call-ID, To and From are needed to identify a call leg. - The distinction between call and call leg matters in calls - with multiple responses from a forked request. The "tag" is - added to the To header field in the response to allow - forking of future requests for the same call by proxies, - while addressing only one of the possibly several - responding user agent servers. It also allows several - instances of the callee to send requests that can be - distinguished. - - - - -Handley, et al. Standards Track [Page 67] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -6.38 Unsupported - - The Unsupported response-header field lists the features not - supported by the server. See Section 6.30 for a usage example and - motivation. - - Syntax: - - - - Unsupported = "Unsupported" ":" 1#option-tag - - -6.39 User-Agent - - The User-Agent general-header field contains information about the - client user agent originating the request. The syntax and semantics - are defined in [H14.42]. - -6.40 Via - - The Via field indicates the path taken by the request so far. This - prevents request looping and ensures replies take the same path as - the requests, which assists in firewall traversal and other unusual - routing situations. - -6.40.1 Requests - - The client originating the request MUST insert into the request a Via - field containing its host name or network address and, if not the - default port number, the port number at which it wishes to receive - responses. (Note that this port number can differ from the UDP source - port number of the request.) A fully-qualified domain name is - RECOMMENDED. Each subsequent proxy server that sends the request - onwards MUST add its own additional Via field before any existing Via - fields. A proxy that receives a redirection (3xx) response and then - searches recursively, MUST use the same Via headers as on the - original proxied request. - - A proxy SHOULD check the top-most Via header field to ensure that it - contains the sender's correct network address, as seen from that - proxy. If the sender's address is incorrect, the proxy MUST add an - additional "received" attribute, as described 6.40.2. - - - A host behind a network address translator (NAT) or - firewall may not be able to insert a network address into - the Via header that can be reached by the next hop beyond - - - -Handley, et al. Standards Track [Page 68] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - the NAT. Use of the received attribute allows SIP requests - to traverse NAT's which only modify the source IP address. - NAT's which modify port numbers, called Network Address - Port Translator's (NAPT) will not properly pass SIP when - transported on UDP, in which case an application layer - gateway is required. When run over TCP, SIP stands a better - chance of traversing NAT's, since its behavior is similar - to HTTP in this case (but of course on different ports). - - A proxy sending a request to a multicast address MUST add the "maddr" - parameter to its Via header field, and SHOULD add the "ttl" - parameter. If a server receives a request which contained an "maddr" - parameter in the topmost Via field, it SHOULD send the response to - the multicast address listed in the "maddr" parameter. - - If a proxy server receives a request which contains its own address - in the Via header value, it MUST respond with a 482 (Loop Detected) - status code. - - A proxy server MUST NOT forward a request to a multicast group which - already appears in any of the Via headers. - - - This prevents a malfunctioning proxy server from causing - loops. Also, it cannot be guaranteed that a proxy server - can always detect that the address returned by a location - service refers to a host listed in the Via list, as a - single host may have aliases or several network interfaces. - -6.40.2 Receiver-tagged Via Header Fields - - Normally, every host that sends or forwards a SIP message adds a Via - field indicating the path traversed. However, it is possible that - Network Address Translators (NATs) changes the source address and - port of the request (e.g., from net-10 to a globally routable - address), in which case the Via header field cannot be relied on to - route replies. To prevent this, a proxy SHOULD check the top-most Via - header field to ensure that it contains the sender's correct network - address, as seen from that proxy. If the sender's address is - incorrect, the proxy MUST add a "received" parameter to the Via - header field inserted by the previous hop. Such a modified Via header - field is known as a receiver-tagged Via header field. An example is: - - - Via: SIP/2.0/UDP erlang.bell-telephone.com:5060 - Via: SIP/2.0/UDP 10.0.0.1:5060 ;received=199.172.136.3 - - - - - -Handley, et al. Standards Track [Page 69] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - In this example, the message originated from 10.0.0.1 and traversed a - NAT with the external address border.ieee.org (199.172.136.3) to - reach erlang.bell-telephone.com. The latter noticed the mismatch, - and added a parameter to the previous hop's Via header field, - containing the address that the packet actually came from. (Note that - the NAT border.ieee.org is not a SIP server.) - -6.40.3 Responses - - Via header fields in responses are processed by a proxy or UAC - according to the following rules: - - 1. The first Via header field should indicate the proxy or - client processing this response. If it does not, discard - the message. Otherwise, remove this Via field. - - 2. If there is no second Via header field, this response is - destined for this client. Otherwise, the processing depends - on whether the Via field contains a "maddr" parameter or is - a receiver-tagged field: - - - If the second Via header field contains a "maddr" - parameter, send the response to the multicast address - listed there, using the port indicated in "sent-by", or - port 5060 if none is present. The response SHOULD be sent - using the TTL indicated in the "ttl" parameter, or with a - TTL of 1 if that parameter is not present. For - robustness, responses MUST be sent to the address - indicated in the "maddr" parameter even if it is not a - multicast address. - - - If the second Via header field does not contain a "maddr" - parameter and is a receiver-tagged field (Section - 6.40.2), send the message to the address in the - "received" parameter, using the port indicated in the - "sent-by" value, or using port 5060 if none is present. - - - If neither of the previous cases apply, send the message - to the address indicated by the "sent-by" value in the - second Via header field. - -6.40.4 User Agent and Redirect Servers - - A UAS or redirect server sends a response based on one of the - following rules: - - o If the first Via header field in the request contains a - "maddr" parameter, send the response to the multicast address - - - -Handley, et al. Standards Track [Page 70] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - listed there, using the port indicated in "sent-by", or port - 5060 if none is present. The response SHOULD be sent using the - TTL indicated in the "ttl" parameter, or with a TTL of 1 if - that parameter is not present. For robustness, responses MUST - be sent to the address indicated in the "maddr" parameter even - if it is not a multicast address. - - o If the address in the "sent-by" value of the first Via field - differs from the source address of the packet, send the - response to the actual packet source address, similar to the - treatment for receiver-tagged Via header fields (Section - 6.40.2). - - o If neither of these conditions is true, send the response to - the address contained in the "sent-by" value. If the request - was sent using TCP, use the existing TCP connection if - available. - -6.40.5 Syntax - - The format for a Via header field is shown in Fig. 11. The defaults - for "protocol-name" and "transport" are "SIP" and "UDP", - respectively. The "maddr" parameter, designating the multicast - address, and the "ttl" parameter, designating the time-to-live (TTL) - value, are included only if the request was sent via multicast. The - "received" parameter is added only for receiver-added Via fields - (Section 6.40.2). For reasons of privacy, a client or proxy may wish - to hide its Via information by encrypting it (see Section 6.22). The - "hidden" parameter is included if this header field was hidden by the - upstream proxy (see 6.22). Note that privacy of the proxy relies on - the cooperation of the next hop, as the next-hop proxy will, by - necessity, know the IP address and port number of the source host. - - - The "branch" parameter is included by every forking proxy. The token - MUST be unique for each distinct request generated when a proxy - forks. CANCEL requests MUST have the same branch value as the - corresponding forked request. When a response arrives at the proxy it - can use the branch value to figure out which branch the response - corresponds to. A proxy which generates a single request (non- - forking) MAY also insert the "branch" parameter. The identifier has - to be unique only within a set of isomorphic requests. - - - Via: SIP/2.0/UDP first.example.com:4000;ttl=16 - ;maddr=224.2.0.1 ;branch=a7c6a8dlze (Example) - Via: SIP/2.0/UDP adk8 - - - - -Handley, et al.

Not all HTTP/1.1 response codes are appropriate, and only - those that are appropriate are given here. Other HTTP/1.1 response - codes SHOULD NOT be used. Response codes not defined by HTTP/1.1 have - codes x80 upwards to avoid clashes with future HTTP response codes. - Also, SIP defines a new class, 6xx. The default behavior for unknown - response codes is given for each category of codes. - -7.1 Informational 1xx - - Informational responses indicate that the server or proxy contacted - is performing some further action and does not yet have a definitive - response. The client SHOULD wait for a further response from the - server, and the server SHOULD send such a response without further - prompting. A server SHOULD send a 1xx response if it expects to take - more than 200 ms to obtain a final response. A server MAY issue zero - or more 1xx responses, with no restriction on their ordering or - uniqueness. Note that 1xx responses are not transmitted reliably, - that is, they do not cause the client to send an ACK. Servers are - free to retransmit informational responses and clients can inquire - about the current state of call processing by re-sending the request. - -7.1.1 100 Trying - - Some unspecified action is being taken on behalf of this call (e.g., - a database is being consulted), but the user has not yet been - located. - -7.1.2 180 Ringing - - The called user agent has located a possible location where the user - has registered recently and is trying to alert the user. - -7.1.3 181 Call Is Being Forwarded - - A proxy server MAY use this status code to indicate that the call is - being forwarded to a different set of destinations. - - - - - - - -Handley, et al. Standards Track [Page 75] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -7.1.4 182 Queued - - The called party is temporarily unavailable, but the callee has - decided to queue the call rather than reject it. When the callee - becomes available, it will return the appropriate final status - response. The reason phrase MAY give further details about the status - of the call, e.g., "5 calls queued; expected waiting time is 15 - minutes". The server MAY issue several 182 responses to update the - caller about the status of the queued call. - -7.2 Successful 2xx - - The request was successful and MUST terminate a search. - -7.2.1 200 OK - - The request has succeeded. The information returned with the response - depends on the method used in the request, for example: - - BYE: The call has been terminated. The message body is empty. - - CANCEL: The search has been cancelled. The message body is empty. - - INVITE: The callee has agreed to participate; the message body - indicates the callee's capabilities. - - OPTIONS: The callee has agreed to share its capabilities, included in - the message body. - - REGISTER: The registration has succeeded. The client treats the - message body according to its Content-Type. - -7.3 Redirection 3xx - - 3xx responses give information about the user's new location, or - about alternative services that might be able to satisfy the call. - They SHOULD terminate an existing search, and MAY cause the initiator - to begin a new search if appropriate. - - Any redirection (3xx) response MUST NOT suggest any of the addresses - in the Via (Section 6.40) path of the request in the Contact header - field. (Addresses match if their host and port number match.) - - To avoid forwarding loops, a user agent client or proxy MUST check - whether the address returned by a redirect server equals an address - tried earlier. - - - - - -Handley, et al. Standards Track [Page 76] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -7.3.1 300 Multiple Choices - - The address in the request resolved to several choices, each with its - own specific location, and the user (or user agent) can select a - preferred communication end point and redirect its request to that - location. - - The response SHOULD include an entity containing a list of resource - characteristics and location(s) from which the user or user agent can - choose the one most appropriate, if allowed by the Accept request - header. The entity format is specified by the media type given in the - Content-Type header field. The choices SHOULD also be listed as - Contact fields (Section 6.13). Unlike HTTP, the SIP response MAY - contain several Contact fields or a list of addresses in a Contact - field. User agents MAY use the Contact header field value for - automatic redirection or MAY ask the user to confirm a choice. - However, this specification does not define any standard for such - automatic selection. - - - This status response is appropriate if the callee can be - reached at several different locations and the server - cannot or prefers not to proxy the request. - -7.3.2 301 Moved Permanently - - The user can no longer be found at the address in the Request-URI and - the requesting client SHOULD retry at the new address given by the - Contact header field (Section 6.13). The caller SHOULD update any - local directories, address books and user location caches with this - new value and redirect future requests to the address(es) listed. - -7.3.3 302 Moved Temporarily - - The requesting client SHOULD retry the request at the new address(es) - given by the Contact header field (Section 6.13). The duration of - the redirection can be indicated through an Expires (Section 6.20) - header. If there is no explicit expiration time, the address is only - valid for this call and MUST NOT be cached for future calls. - -7.3.4 305 Use Proxy - - The requested resource MUST be accessed through the proxy given by - the Contact field. The Contact field gives the URI of the proxy. The - recipient is expected to repeat this single request via the proxy. - 305 responses MUST only be generated by user agent servers. - - - - - -Handley, et al. Standards Track [Page 77] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -7.3.5 380 Alternative Service - - The call was not successful, but alternative services are possible. - The alternative services are described in the message body of the - response. Formats for such bodies are not defined here, and may be - the subject of future standardization. - -7.4 Request Failure 4xx - - 4xx responses are definite failure responses from a particular - server. The client SHOULD NOT retry the same request without - modification (e.g., adding appropriate authorization). However, the - same request to a different server might be successful. - -7.4.1 400 Bad Request - - The request could not be understood due to malformed syntax. - -7.4.2 401 Unauthorized - - The request requires user authentication. - -7.4.3 402 Payment Required - - Reserved for future use. - -7.4.4 403 Forbidden - - The server understood the request, but is refusing to fulfill it. - Authorization will not help, and the request SHOULD NOT be repeated. - -7.4.5 404 Not Found - - The server has definitive information that the user does not exist at - the domain specified in the Request-URI. This status is also returned - if the domain in the Request-URI does not match any of the domains - handled by the recipient of the request. - -7.4.6 405 Method Not Allowed - - The method specified in the Request-Line is not allowed for the - address identified by the Request-URI.

The proxy MUST - return a Proxy-Authenticate header field (section 6.26) containing a - challenge applicable to the proxy for the requested resource. The - client MAY repeat the request with a suitable Proxy-Authorization - header field (section 6.27). SIP access authentication is explained - in section 13.2 and 14. - - This status code is used for applications where access to the - communication channel (e.g., a telephony gateway) rather than the - callee requires authentication. - -7.4.9 408 Request Timeout - - The server could not produce a response, e.g., a user location, - within the time indicated in the Expires request-header field. The - client MAY repeat the request without modifications at any later - time. - -7.4.10 409 Conflict - - The request could not be completed due to a conflict with the current - state of the resource. This response is returned if the action - parameter in a REGISTER request conflicts with existing - registrations. - -7.4.11 410 Gone - - The requested resource is no longer available at the server and no - forwarding address is known. This condition is expected to be - considered permanent. If the server does not know, or has no facility - to determine, whether or not the condition is permanent, the status - code 404 (Not Found) SHOULD be used instead. - -7.4.12 411 Length Required - - The server refuses to accept the request without a defined Content- - Length. The client MAY repeat the request if it adds a valid - Content-Length header field containing the length of the message-body - in the request message. - - - -Handley, et al.

The server SHOULD return a list of - acceptable formats using the Accept, Accept-Encoding and Accept- - Language header fields. - -7.4.16 420 Bad Extension - - The server did not understand the protocol extension specified in a - Require (Section 6.30) header field. - -7.4.17 480 Temporarily Unavailable - - The callee's end system was contacted successfully but the callee is - currently unavailable (e.g., not logged in or logged in in such a - manner as to preclude communication with the callee). The response - MAY indicate a better time to call in the Retry-After header. The - user could also be available elsewhere (unbeknownst to this host), - thus, this response does not terminate any searches. The reason - phrase SHOULD indicate a more precise cause as to why the callee is - unavailable. This value SHOULD be setable by the user agent. Status - 486 (Busy Here) MAY be used to more precisely indicate a particular - reason for the call failure. - - This status is also returned by a redirect server that recognizes the - user identified by the Request-URI, but does not currently have a - valid forwarding location for that user. - - - - - - -Handley, et al. Standards Track [Page 80] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -7.4.18 481 Call Leg/Transaction Does Not Exist - - This status is returned under two conditions: The server received a - BYE request that does not match any existing call leg or the server - received a CANCEL request that does not match any existing - transaction. (A server simply discards an ACK referring to an unknown - transaction.) - -7.4.19 482 Loop Detected - - The server received a request with a Via (Section 6.40) path - containing itself. - -7.4.20 483 Too Many Hops - - The server received a request that contains more Via entries (hops) - (Section 6.40) than allowed by the Max-Forwards (Section 6.23) header - field. - -7.4.21 484 Address Incomplete - - The server received a request with a To (Section 6.37) address or - Request-URI that was incomplete. Additional information SHOULD be - provided. - - - This status code allows overlapped dialing. With overlapped - dialing, the client does not know the length of the dialing - string. It sends strings of increasing lengths, prompting - the user for more input, until it no longer receives a 484 - status response. - -7.4.22 485 Ambiguous - - The callee address provided in the request was ambiguous. The - response MAY contain a listing of possible unambiguous addresses in - Contact headers. - - Revealing alternatives can infringe on privacy concerns of the user - or the organization. It MUST be possible to configure a server to - respond with status 404 (Not Found) or to suppress the listing of - possible choices if the request address was ambiguous. - - Example response to a request with the URL lee@example.com : - - 485 Ambiguous SIP/2.0 - Contact: Carol Lee - - - - -Handley, et al.

Foote - - - - Some email and voice mail systems provide this - functionality. A status code separate from 3xx is used - since the semantics are different: for 300, it is assumed - that the same person or service will be reached by the - choices provided. While an automated choice or sequential - search makes sense for a 3xx response, user intervention is - required for a 485 response. - -7.4.23 486 Busy Here - - The callee's end system was contacted successfully but the callee is - currently not willing or able to take additional calls. The response - MAY indicate a better time to call in the Retry-After header. The - user could also be available elsewhere, such as through a voice mail - service, thus, this response does not terminate any searches. Status - 600 (Busy Everywhere) SHOULD be used if the client knows that no - other end system will be able to accept this call. - -7.5 Server Failure 5xx - - 5xx responses are failure responses given when a server itself has - erred. They are not definitive failures, and MUST NOT terminate a - search if other possible locations remain untried. - -7.5.1 500 Server Internal Error - - The server encountered an unexpected condition that prevented it from - fulfilling the request. The client MAY display the specific error - condition, and MAY retry the request after several seconds. - -7.5.2 501 Not Implemented - - The server does not support the functionality required to fulfill the - request. This is the appropriate response when the server does not - recognize the request method and is not capable of supporting it for - any user. - -7.5.3 502 Bad Gateway - - The server, while acting as a gateway or proxy, received an invalid - response from the downstream server it accessed in attempting to - fulfill the request. - - - - -Handley, et al. Standards Track [Page 82] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -7.5.4 503 Service Unavailable - - The server is currently unable to handle the request due to a - temporary overloading or maintenance of the server. The implication - is that this is a temporary condition which will be alleviated after - some delay. If known, the length of the delay MAY be indicated in a - Retry-After header. If no Retry-After is given, the client MUST - handle the response as it would for a 500 response. - - Note: The existence of the 503 status code does not imply that a - server has to use it when becoming overloaded. Some servers MAY wish - to simply refuse the connection. - -7.5.5 504 Gateway Time-out - - The server, while acting as a gateway, did not receive a timely - response from the server (e.g., a location server) it accessed in - attempting to complete the request. - -7.5.6 505 Version Not Supported - - The server does not support, or refuses to support, the SIP protocol - version that was used in the request message. The server is - indicating that it is unable or unwilling to complete the request - using the same major version as the client, other than with this - error message. The response MAY contain an entity describing why that - version is not supported and what other protocols are supported by - that server. The format for such an entity is not defined here and - may be the subject of future standardization. - -7.6 Global Failures 6xx - - 6xx responses indicate that a server has definitive information about - a particular user, not just the particular instance indicated in the - Request-URI. All further searches for this user are doomed to failure - and pending searches SHOULD be terminated. - -7.6.1 600 Busy Everywhere - - The callee's end system was contacted successfully but the callee is - busy and does not wish to take the call at this time. The response - MAY indicate a better time to call in the Retry-After header. If the - callee does not wish to reveal the reason for declining the call, the - callee uses status code 603 (Decline) instead.

Searching for the user - elsewhere will not yield any results. - -7.6.4 606 Not Acceptable - - The user's agent was contacted successfully but some aspects of the - session description such as the requested media, bandwidth, or - addressing style were not acceptable. - - A 606 (Not Acceptable) response means that the user wishes to - communicate, but cannot adequately support the session described. The - 606 (Not Acceptable) response MAY contain a list of reasons in a - Warning header field describing why the session described cannot be - supported. Reasons are listed in Section 6.41. It is hoped that - negotiation will not frequently be needed, and when a new user is - being invited to join an already existing conference, negotiation may - not be possible. It is up to the invitation initiator to decide - whether or not to act on a 606 (Not Acceptable) response. - -8 SIP Message Body - -8.1 Body Inclusion - - Requests MAY contain message bodies unless otherwise noted. Within - this specification, the BYE request MUST NOT contain a message body. - For ACK, INVITE and OPTIONS, the message body is always a session - description. The use of message bodies for REGISTER requests is for - further study. - - For response messages, the request method and the response status - code determine the type and interpretation of any message body. All - responses MAY include a body. Message bodies for 1xx responses - contain advisory information about the progress of the request. 2xx - responses to INVITE requests contain session descriptions. In 3xx - responses, the message body MAY contain the description of - alternative destinations or services, as described in Section 7.3. - For responses with status 400 or greater, the message body MAY - - - - - -Handley, et al. Standards Track [Page 84] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - contain additional, human-readable information about the reasons for - failure. It is RECOMMENDED that information in 1xx and 300 and - greater responses be of type text/plain or text/html - -8.2 Message Body Type - - The Internet media type of the message body MUST be given by the - Content-Type header field. If the body has undergone any encoding - (such as compression) then this MUST be indicated by the Content- - Encoding header field, otherwise Content-Encoding MUST be omitted. If - applicable, the character set of the message body is indicated as - part of the Content-Type header-field value. - -8.3 Message Body Length - - The body length in bytes SHOULD be given by the Content-Length header - field. Section 6.15 describes the behavior in detail. - - The "chunked" transfer encoding of HTTP/1.1 MUST NOT be used for SIP. - (Note: The chunked encoding modifies the body of a message in order - to transfer it as a series of chunks, each with its own size - indicator.) - -9 Compact Form - - When SIP is carried over UDP with authentication and a complex - session description, it may be possible that the size of a request or - response is larger than the MTU.

(SIP requests are said to be idempotent , i.e., - receiving more than one copy of a request does not change the server - state.) - - After receiving a CANCEL request from an upstream client, a stateful - proxy server MAY send a CANCEL on all branches where it has not yet - received a final response. - - When a user agent receives a request, it checks the Call-ID against - those of in-progress calls. If the Call-ID was found, it compares the - tag value of To with the user's tag and rejects the request if the - - - -Handley, et al. Standards Track [Page 86] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - two do not match. If the From header, including any tag value, - matches the value for an existing call leg, the server compares the - CSeq header field value. If less than or equal to the current - sequence number, the request is a retransmission. Otherwise, it is a - new request. If the From header does not match an existing call leg, - a new call leg is created. - - If the Call-ID was not found, a new call leg is created, with entries - for the To, From and Call-ID headers. In this case, the To header - field should not have contained a tag. The server returns a response - containing the same To value, but with a unique tag added. The tag - MAY be omitted if the request contained only one Via header field. - -10.1.2 Responses - - A server MAY issue one or more provisional responses at any time - before sending a final response. If a stateful proxy, user agent - server, redirect server or registrar cannot respond to a request with - a final response within 200 ms, it SHOULD issue a provisional (1xx) - response as soon as possible. Stateless proxies MUST NOT issue - provisional responses on their own. - - Responses are mapped to requests by the matching To, From, Call-ID, - CSeq headers and the branch parameter of the first Via header. - Responses terminate request retransmissions even if they have Via - headers that cause them to be delivered to an upstream client. - - A stateful proxy may receive a response that it does not have state - for, that is, where it has no a record of an associated request. If - the Via header field indicates that the upstream server used TCP, the - proxy actively opens a TCP connection to that address. Thus, proxies - have to be prepared to receive responses on the incoming side of - passive TCP connections, even though most responses will arrive on - the incoming side of an active connection. (An active connection is a - TCP connection initiated by the proxy, a passive connection is one - accepted by the proxy, but initiated by another entity.) - - 100 responses SHOULD NOT be forwarded, other 1xx responses MAY be - forwarded, possibly after the server eliminates responses with status - codes that had already been sent earlier. 2xx responses are forwarded - according to the Via header. Once a stateful proxy has received a 2xx - response, it MUST NOT forward non-2xx final responses. Responses - with status 300 and higher are retransmitted by each stateful proxy - until the next upstream proxy sends an ACK (see below for timing - details) or CANCEL. - - - - - - -Handley, et al. Standards Track [Page 87] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - A stateful proxy SHOULD maintain state for at least 32 seconds after - the receipt of the first definitive non-200 response, in order to - handle retransmissions of the response. - - - The 32 second window is given by the maximum retransmission - duration of 200-class responses using the default timers, - in case the ACK is lost somewhere on the way to the called - user agent or the next stateful proxy. - -10.2 Source Addresses, Destination Addresses and Connections - -10.2.1 Unicast UDP - - Responses are returned to the address listed in the Via header field - (Section 6.40), not the source address of the request. - - - Recall that responses are not generated by the next-hop - stateless server, but generated by either a proxy server or - the user agent server. Thus, the stateless proxy can only - use the Via header field to forward the response. - -10.2.2 Multicast UDP - - Requests MAY be multicast; multicast requests likely feature a host- - independent Request-URI. This request SHOULD be scoped to ensure it - is not forwarded beyond the boundaries of the administrative system. - This MAY be done with either TTL or administrative scopes[25], - depending on what is implemented in the network. - - A client receiving a multicast query does not have to check whether - the host part of the Request-URI matches its own host or domain name. - If the request was received via multicast, the response is also - returned via multicast. Responses to multicast requests are multicast - with the same TTL as the request, where the TTL is derived from the - ttl parameter in the Via header (Section 6.40). - - To avoid response implosion, servers MUST NOT answer multicast - requests with a status code other than 2xx or 6xx. The server delays - its response by a random interval uniformly distributed between zero - and one second. Servers MAY suppress responses if they hear a lower- - numbered or 6xx response from another group member prior to sending. - Servers do not respond to CANCEL requests received via multicast to - avoid request implosion. A proxy or UAC SHOULD send a CANCEL on - receiving the first 2xx or 6xx response to a multicast request. - - - - - -Handley, et al. Standards Track [Page 88] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Server response suppression is a MAY since it requires a - server to violate some basic message processing rules. Lets - say A sends a multicast request, and it is received by B,C, - and D. B sends a 200 response. The topmost Via field in the - response will contain the address of A. C will also receive - this response, and could use it to suppress its own - response. However, C would normally not examine this - response, as the topmost Via is not its own. Normally, a - response received with an incorrect topmost Via MUST be - dropped, but not in this case. To distinguish this packet - from a misrouted or multicast looped packet is fairly - complex, and for this reason the procedure is a MAY. The - CANCEL, instead, provides a simpler and more standard way - to perform response suppression. It is for this reason that - the use of CANCEL here is a SHOULD - -10.3 TCP - - A single TCP connection can serve one or more SIP transactions. A - transaction contains zero or more provisional responses followed by - one or more final responses. (Typically, transactions contain exactly - one final response, but there are exceptional circumstances, where, - for example, multiple 200 responses can be generated.) - - The client SHOULD keep the connection open at least until the first - final response arrives. If the client closes or resets the TCP - connection prior to receiving the first final response, the server - treats this action as equivalent to a CANCEL request. - - - This behavior makes it less likely that malfunctioning - clients cause a proxy server to keep connection state - indefinitely. - - The server SHOULD NOT close the TCP connection until it has sent its - final response, at which point it MAY close the TCP connection if it - wishes to. However, normally it is the client's responsibility to - close the connection. - - If the server leaves the connection open, and if the client so - desires it MAY re-use the connection for further SIP requests or for - requests from the same family of protocols (such as HTTP or stream - control commands). - - - - - - - - -Handley, et al. Standards Track [Page 89] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - If a server needs to return a response to a client and no longer has - a connection open to that client, it MAY open a connection to the - address listed in the Via header. Thus, a proxy or user agent MUST be - prepared to receive both requests and responses on a "passive" - connection. - -10.4 Reliability for BYE, CANCEL, OPTIONS, REGISTER Requests - -10.4.1 UDP - - A SIP client using UDP SHOULD retransmit a BYE, CANCEL, OPTIONS, or - REGISTER request with an exponential backoff, starting at a T1 second - interval, doubling the interval for each packet, and capping off at a - T2 second interval. This means that after the first packet is sent, - the second is sent T1 seconds later, the next 2*T1 seconds after - that, the next 4*T1 seconds after that, and so on, until the interval - hits T2. Subsequent retransmissions are spaced by T2 seconds. If the - client receives a provisional response, it continues to retransmit - the request, but with an interval of T2 seconds. Retransmissions - cease when the client has sent a total of eleven packets, or receives - a definitive response. Default values for T1 and T2 are 500 ms and 4 - s, respectively. Clients MAY use larger values, but SHOULD NOT use - smaller ones. Servers retransmit the response upon receipt of a - request retransmission. After the server sends a final response, it - cannot be sure the client has received the response, and thus SHOULD - cache the results for at least 10*T2 seconds to avoid having to, for - example, contact the user or location server again upon receiving a - request retransmission. - - - Use of the exponential backoff is for congestion control - purposes. However, the back-off must cap off, since request - retransmissions are used to trigger response - retransmissions at the server. Without a cap, the loss of a - single response could significantly increase transaction - latencies. - - The value of the initial retransmission timer is smaller than that - that for TCP since it is expected that network paths suitable for - interactive communications have round-trip times smaller than 500 ms. - For congestion control purposes, the retransmission count has to be - bounded. Given that most transactions are expected to consist of one - request and a few responses, round-trip time estimation is not likely - to be very useful. If RTT estimation is desired to more quickly - discover a missing final response, each request retransmission needs - to be labeled with its own Timestamp (Section 6.36), returned in the - response. The server caches the result until it can be sure that the - client will not retransmit the same request again. - - - -Handley, et al. Standards Track [Page 90] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Each server in a proxy chain generates its own final response to a - CANCEL request. The server responds immediately upon receipt of the - CANCEL request rather than waiting until it has received final - responses from the CANCEL requests it generates. - - BYE and OPTIONS final responses are generated by redirect and user - agent servers; REGISTER final responses are generated by registrars. - Note that in contrast to the reliability mechanism described in - Section 10.5, responses to these requests are not retransmitted - periodically and not acknowledged via ACK. - -10.4.2 TCP - - Clients using TCP do not need to retransmit requests. - -10.5 Reliability for INVITE Requests - - Special considerations apply for the INVITE method. - - 1. After receiving an invitation, considerable time can elapse - before the server can determine the outcome. For example, - if the called party is "rung" or extensive searches are - performed, delays between the request and a definitive - response can reach several tens of seconds. If either - caller or callee are automated servers not directly - controlled by a human being, a call attempt could be - unbounded in time. - - 2. If a telephony user interface is modeled or if we need to - interface to the PSTN, the caller's user interface will - provide "ringback", a signal that the callee is being - alerted. (The status response 180 (Ringing) MAY be used to - initiate ringback.) Once the callee picks up, the caller - needs to know so that it can enable the voice path and stop - ringback. The callee's response to the invitation could get - lost. Unless the response is transmitted reliably, the - caller will continue to hear ringback while the callee - assumes that the call exists. - - 3. The client has to be able to terminate an on-going request, - e.g., because it is no longer willing to wait for the - connection or search to succeed. The server will have to - wait several retransmission intervals to interpret the lack - of request retransmissions as the end of a call. If the - call succeeds shortly after the caller has given up, the - callee will "pick up the phone" and not be "connected". - - - - - -Handley, et al. Standards Track [Page 91] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -10.5.1 UDP - - For UDP, A SIP client SHOULD retransmit a SIP INVITE request with an - interval that starts at T1 seconds, and doubles after each packet - transmission. The client ceases retransmissions if it receives a - provisional or definitive response, or once it has sent a total of 7 - request packets. - - A server which transmits a provisional response should retransmit it - upon reception of a duplicate request. A server which transmits a - final response should retransmit it with an interval that starts at - T1 seconds, and doubles for each subsequent packet. Response - retransmissions cease when any one of the following occurs: - - 1. An ACK request for the same transaction is received; - - 2. a BYE request for the same call leg is received; - - 3. a CANCEL request for the same call leg is received and the - final response status was equal or greater to 300; - - 4. the response has been transmitted 7 times. - - Only the user agent client generates an ACK for 2xx final responses, - If the response contained a Contact header field, the ACK MAY be sent - to the address listed in that Contact header field. If the response - did not contain a Contact header, the client uses the same To header - field and Request-URI as for the INVITE request and sends the ACK to - the same destination as the original INVITE request. ACKs for final - responses other than 2xx are sent to the same server that the - original request was sent to, using the same Request-URI as the - original request. Note, however, that the To header field in the ACK - is copied from the response being acknowledged, not the request, and - thus MAY additionally contain the tag parameter. Also note than - unlike 2xx final responses, a proxy generates an ACK for non-2xx - final responses. - - The ACK request MUST NOT be acknowledged to prevent a response-ACK - feedback loop. Fig. 12 and 13 show the client and server state - diagram for invitations. - - - - - The mechanism in Sec. 10.4 would not work well for INVITE - because of the long delays between INVITE and a final - response. If the 200 response were to get lost, the callee - would believe the call to exist, but the voice path would - - - -Handley, et al.

For simplicity, - we also retransmit non-2xx responses, although that is not - strictly necessary. - -10.6 Reliability for ACK Requests - - The ACK request does not generate responses. It is only generated - when a response to an INVITE request arrives (see Section 10.5). This - behavior is independent of the transport protocol. Note that the ACK - request MAY take a different path than the original INVITE request, - and MAY even cause a new TCP connection to be opened in order to send - it. - -10.7 ICMP Handling - - Handling of ICMP messages in the case of UDP messages is - straightforward. For requests, a host, network, port, or protocol - unreachable error SHOULD be treated as if a 400-class response was - received. For responses, these errors SHOULD cause the server to - cease retransmitting the response. - - Source quench ICMP messages SHOULD be ignored. TTL exceeded errors - SHOULD be ignored. Parameter problem errors SHOULD be treated as if a - 400-class response was received. - -11 Behavior of SIP User Agents - - This section describes the rules for user agent client and servers - for generating and processing requests and responses. - - - - -Handley, et al. Standards Track [Page 95] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -11.1 Caller Issues Initial INVITE Request - - When a user agent client desires to initiate a call, it formulates an - INVITE request. The To field in the request contains the address of - the callee. The Request-URI contains the same address. The From field - contains the address of the caller. If the From address can appear - in requests generated by other user agent clients for the same call, - the caller MUST insert the tag parameter in the From field. A UAC MAY - optionally add a Contact header containing an address where it would - like to be contacted for transactions from the callee back to the - caller. - -11.2 Callee Issues Response - - When the initial INVITE request is received at the callee, the callee - can accept, redirect, or reject the call. In all of these cases, it - formulates a response. The response MUST copy the To, From, Call-ID, - CSeq and Via fields from the request. Additionally, the responding - UAS MUST add the tag parameter to the To field in the response if the - request contained more than one Via header field. Since a request - from a UAC may fork and arrive at multiple hosts, the tag parameter - serves to distinguish, at the UAC, multiple responses from different - UAS's. The UAS MAY add a Contact header field in the response. It - contains an address where the callee would like to be contacted for - subsequent transactions, including the ACK for the current INVITE. - The UAS stores the values of the To and From field, including any - tags. These become the local and remote addresses of the call leg, - respectively. - -11.3 Caller Receives Response to Initial Request - - Multiple responses may arrive at the UAC for a single INVITE request, - due to a forking proxy. Each response is distinguished by the "tag" - parameter in the To header field, and each represents a distinct call - leg. The caller MAY choose to acknowledge or terminate the call with - each responding UAS. To acknowledge, it sends an ACK request, and to - terminate it sends a BYE request. The To header field in the ACK or - BYE MUST be the same as the To field in the 200 response, including - any tag. The From header field MUST be the same as the From header - field in the 200 (OK) response, including any tag. The Request-URI of - the ACK or BYE request MAY be set to whatever address was found in - the Contact header field in the 200 (OK) response, if present. - Alternately, a UAC may copy the address from the To header field into - the Request-URI. The UAC also notes the value of the To and From - header fields in each response. For each call leg, the To header - field becomes the remote address, and the From header field becomes - the local address. - - - - -Handley, et al. Standards Track [Page 96] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -11.4 Caller or Callee Generate Subsequent Requests - - Once the call has been established, either the caller or callee MAY - generate INVITE or BYE requests to change or terminate the call. - Regardless of whether the caller or callee is generating the new - request, the header fields in the request are set as follows. For the - desired call leg, the To header field is set to the remote address, - and the From header field is set to the local address (both including - any tags). The Contact header field MAY be different than the Contact - header field sent in a previous response or request. The Request-URI - MAY be set to the value of the Contact header field received in a - previous request or response from the remote party, or to the value - of the remote address. - -11.5 Receiving Subsequent Requests - - When a request is received subsequently, the following checks are - made: - - 1. If the Call-ID is new, the request is for a new call, - regardless of the values of the To and From header fields. - - 2. If the Call-ID exists, the request is for an existing call. - If the To, From, Call-ID, and CSeq values exactly match - (including tags) those of any requests received previously, - the request is a retransmission. - - 3. If there was no match to the previous step, the To and From - fields are compared against existing call leg local and - remote addresses. If there is a match, and the CSeq in the - request is higher than the last CSeq received on that leg, - the request is a new transaction for an existing call leg. - -12 Behavior of SIP Proxy and Redirect Servers - - This section describes behavior of SIP redirect and proxy servers in - detail. Proxy servers can "fork" connections, i.e., a single incoming - request spawns several outgoing (client) requests. - -12.1 Redirect Server - - A redirect server does not issue any SIP requests of its own. After - receiving a request other than CANCEL, the server gathers the list of - alternative locations and returns a final response of class 3xx or it - refuses the request. For well-formed CANCEL requests, it SHOULD - return a 2xx response. This response ends the SIP transaction. The - - - - - -Handley, et al. Standards Track [Page 97] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - redirect server maintains transaction state for the whole SIP - transaction. It is up to the client to detect forwarding loops - between redirect servers. - -12.2 User Agent Server - - User agent servers behave similarly to redirect servers, except that - they also accept requests and can return a response of class 2xx. - -12.3 Proxy Server - - This section outlines processing rules for proxy servers. A proxy - server can either be stateful or stateless. When stateful, a proxy - remembers the incoming request which generated outgoing requests, and - the outgoing requests. A stateless proxy forgets all information once - an outgoing request is generated. A forking proxy SHOULD be stateful. - Proxies that accept TCP connections MUST be stateful. - - - Otherwise, if the proxy were to lose a request, the TCP - client would never retransmit it. - - A stateful proxy SHOULD NOT become stateless until after it sends a - definitive response upstream, and at least 32 seconds after it - received a definitive response. - - A stateful proxy acts as a virtual UAS/UAC. It implements the server - state machine when receiving requests, and the client state machine - for generating outgoing requests, with the exception of receiving a - 2xx response to an INVITE. Instead of generating an ACK, the 2xx - response is always forwarded upstream towards the caller. - Furthermore, ACK's for 200 responses to INVITE's are always proxied - downstream towards the UAS, as they would be for a stateless proxy. - - A stateless proxy does not act as a virtual UAS/UAC (as this would - require state). Rather, a stateless proxy forwards every request it - receives downstream, and every response it receives upstream. - -12.3.1 Proxying Requests - - To prevent loops, a server MUST check if its own address is already - contained in the Via header field of the incoming request. - - The To, From, Call-ID, and Contact tags are copied exactly from the - original request. The proxy SHOULD change the Request-URI to indicate - the server where it intends to send the request. - - - - - -Handley, et al. Standards Track [Page 98] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - A proxy server always inserts a Via header field containing its own - address into those requests that are caused by an incoming request. - Each proxy MUST insert a "branch" parameter (Section 6.40). - -12.3.2 Proxying Responses - - A proxy only processes a response if the topmost Via field matches - one of its addresses. A response with a non-matching top Via field - MUST be dropped. - -12.3.3 Stateless Proxy: Proxying Responses - - A stateless proxy removes its own Via field, and checks the address - in the next Via field. In the case of UDP, the response is sent to - the address listed in the "maddr" tag if present, otherwise to the - "received" tag if present, and finally to the address in the "sent- - by" field. A proxy MUST remain stateful when handling requests - received via TCP. - - A stateless proxy MUST NOT generate its own provisional responses. - -12.3.4 Stateful Proxy: Receiving Requests - - When a stateful proxy receives a request, it checks the To, From - (including tags), Call-ID and CSeq against existing request records. - If the tuple exists, the request is a retransmission. The provisional - or final response sent previously is retransmitted, as per the server - state machine. If the tuple does not exist, the request corresponds - to a new transaction, and the request should be proxied. - - A stateful proxy server MAY generate its own provisional (1xx) - responses. - -12.3.5 Stateful Proxy: Receiving ACKs - - When an ACK request is received, it is either processed locally or - proxied. To make this determination, the To, From, CSeq and Call-ID - fields are compared against those in previous requests. If there is - no match, the ACK request is proxied as if it were an INVITE request. - If there is a match, and if the server had ever sent a 200 response - upstream, the ACK is proxied. If the server had never sent any - responses upstream, the ACK is also proxied. If the server had sent a - 3xx, 4xx, 5xx or 6xx response, but no 2xx response, the ACK is - processed locally if the tag in the To field of the ACK matches the - tag sent by the proxy in the response. - - - - - - -Handley, et al. Standards Track [Page 99] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -12.3.6 Stateful Proxy: Receiving Responses - - When a proxy server receives a response that has passed the Via - checks, the proxy server checks the To (without the tag), From - (including the tag), Call-ID and CSeq against values seen in previous - requests. If there is no match, the response is forwarded upstream to - the address listed in the Via field. If there is a match, the - "branch" tag in the Via field is examined. If it matches a known - branch identifier, the response is for the given branch, and - processed by the virtual client for the given branch. Otherwise, the - response is dropped. - - A stateful proxy should obey the rules in Section 12.4 to determine - if the response should be proxied upstream. If it is to be proxied, - the same rules for stateless proxies above are followed, with the - following addition for TCP. If a request was received via TCP - (indicated by the protocol in the top Via header), the proxy checks - to see if it has a connection currently open to that address. If so, - the response is sent on that connection. Otherwise, a new TCP - connection is opened to the address and port in the Via field, and - the response is sent there. Note that this implies that a UAC or - proxy MUST be prepared to receive responses on the incoming side of a - TCP connection.

SIP supports three complementary forms of encryption to - protect privacy: - - o End-to-end encryption of the SIP message body and certain - sensitive header fields; - - - - -Handley, et al. Standards Track [Page 104] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - o hop-by-hop encryption to prevent eavesdropping that tracks - who is calling whom; - - o hop-by-hop encryption of Via fields to hide the route a - request has taken. - - Not all of the SIP request or response can be encrypted end-to-end - because header fields such as To and Via need to be visible to - proxies so that the SIP request can be routed correctly. Hop-by-hop - encryption encrypts the entire SIP request or response on the wire so - that packet sniffers or other eavesdroppers cannot see who is calling - whom. Hop-by-hop encryption can also encrypt requests and responses - that have been end-to-end encrypted. Note that proxies can still see - who is calling whom, and this information is also deducible by - performing a network traffic analysis, so this provides a very - limited but still worthwhile degree of protection. - - SIP Via fields are used to route a response back along the path taken - by the request and to prevent infinite request loops. However, the - information given by them can also provide useful information to an - attacker. Section 6.22 describes how a sender can request that Via - fields be encrypted by cooperating proxies without compromising the - purpose of the Via field. - - End-to-end encryption relies on keys shared by the two user agents - involved in the request. Typically, the message is sent encrypted - with the public key of the recipient, so that only that recipient can - read the message. All implementations SHOULD support PGP-based - encryption [33] and MAY implement other schemes. - - A SIP request (or response) is end-to-end encrypted by splitting the - message to be sent into a part to be encrypted and a short header - that will remain in the clear. Some parts of the SIP message, namely - the request line, the response line and certain header fields marked - with "n" in the "enc." column in Table 4 and 5 need to be read and - returned by proxies and thus MUST NOT be encrypted end-to-end. - Possibly sensitive information that needs to be made available as - plaintext include destination address (To) and the forwarding path - (Via) of the call. The Authorization header field MUST remain in the - clear if it contains a digital signature as the signature is - generated after encryption, but MAY be encrypted if it contains - "basic" or "digest" authentication. The From header field SHOULD - normally remain in the clear, but MAY be encrypted if required, in - which case some proxies MAY return a 401 (Unauthorized) status if - they require a From field. - - - - - - -Handley, et al.

As only - the proxy that encrypts the field will decrypt it, the algorithm - chosen is entirely up to the proxy implementor. Two methods satisfy - these requirements: - - o The server keeps a cache of Via header fields and the - associated To header field, and replaces the Via header field - with an index into the cache.

The same - cryptographic measures that are used to ensure the authenticity of - the SIP message also serve to authenticate the originator of the - message. However, the "basic" and "digest" authentication mechanism - offer authentication only, without message integrity. - - Transport-layer or network-layer authentication MAY be used for hop- - by-hop authentication. SIP also extends the HTTP WWW-Authenticate - (Section 6.42) and Authorization (Section 6.11) header field and - their Proxy counterparts to include cryptographically strong - signatures. SIP also supports the HTTP "basic" and "digest" schemes - (see Section 14) and other HTTP authentication schemes to be defined - that offer a rudimentary mechanism of ascertaining the identity of - the caller. - - - Since SIP requests are often sent to parties with which no - prior communication relationship has existed, we do not - specify authentication based on shared secrets. - - SIP requests MAY be authenticated using the Authorization header - field to include a digital signature of certain header fields, the - request method and version number and the payload, none of which are - modified between client and called user agent. The Authorization - header field is used in requests to authenticate the request - originator end-to-end to proxies and the called user agent, and in - responses to authenticate the called user agent or proxies returning - their own failure codes. If required, hop-by-hop authentication can - be provided, for example, by the IPSEC Authentication Header. - - SIP does not dictate which digital signature scheme is used for - authentication, but does define how to provide authentication using - PGP in Section 15. As indicated above, SIP implementations MAY also - use "basic" and "digest" authentication and other authentication - mechanisms defined for HTTP. Note that "basic" authentication has - severe security limitations. The following does not apply to these - schemes. - - To cryptographically sign a SIP request, the order of the SIP header - fields is important. When an Authorization header field is present, - it indicates that all header fields following the Authorization - - - -Handley, et al. Standards Track [Page 109] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - header field have been included in the signature. Therefore, hop- - by-hop header fields which MUST or SHOULD be modified by proxies MUST - precede the Authorization header field as they will generally be - modified or added-to by proxy servers. Hop-by-hop header fields - which MAY be modified by a proxy MAY appear before or after the - Authorization header. When they appear before, they MAY be modified - by a proxy. When they appear after, they MUST NOT be modified by a - proxy. To sign a request, a client constructs a message from the - request method (in upper case) followed, without LWS, by the SIP - version number, followed, again without LWS, by the request headers - to be signed and the message body.

(Even encrypted requests contain - enough information to fake a response.) - - Clients need to be particularly careful with 3xx redirection - responses. Thus a client receiving, for example, a 301 (Moved - Permanently) which was not authenticated when the public key of the - called user agent is known to the client, and authentication was - requested in the request SHOULD be treated as suspicious. The correct - behavior in such a case would be for the called-user to form a dated - response containing the Contact field to be used, to sign it, and - give this signed stub response to the proxy that will provide the - redirection. Thus the response can be authenticated correctly. A - client SHOULD NOT automatically redirect such a request to the new - location without alerting the user to the authentication failure - before doing so. - - Another problem might be responses such as 6xx failure responses - which would simply terminate a search, or "4xx" and "5xx" response - failures. - - If TCP is being used, a proxy SHOULD treat 4xx and 5xx responses as - valid, as they will not terminate a search. However, fake 6xx - responses from a rogue proxy terminate a search incorrectly. 6xx - responses SHOULD be authenticated if requested by the client, and - failure to do so SHOULD cause such a client to ignore the 6xx - response and continue a search. - - With UDP, the same problem with 6xx responses exists, but also an - active eavesdropper can generate 4xx and 5xx responses that might - cause a proxy or client to believe a failure occurred when in fact it - did not. Typically 4xx and 5xx responses will not be signed by the - called user agent, and so there is no simple way to detect these - rogue responses. This problem is best prevented by using hop-by-hop - encryption of the SIP request, which removes any additional problems - that UDP might have over TCP. - - These attacks are prevented by having the client require response - authentication and dropping unauthenticated responses. A server user - agent that cannot perform response authentication responds using the - normal Require response of 420 (Bad Extension). - - - - - - - -Handley, et al.

It is obliged to forward the 6xx response back to the client. - The client can then ignore the response, but if it repeats the - request it will probably reach the same rogue proxy again, and the - process will repeat. - -14 SIP Authentication using HTTP Basic and Digest Schemes - - SIP implementations MAY use HTTP's basic and digest authentication - mechanisms to provide a rudimentary form of security. This section - overviews usage of these mechanisms in SIP. The basic operation is - almost completely identical to that for HTTP [36]. This section - outlines this operation, pointing to [36] for details, and noting the - differences when used in SIP. - -14.1 Framework - - The framework for SIP authentication parallels that for HTTP [36]. In - particular, the BNF for auth-scheme, auth-param, challenge, realm, - realm-value, and credentials is identical. The 401 response is used - by user agent servers in SIP to challenge the authorization of a user - agent client. Additionally, registrars and redirect servers MAY make - use of 401 responses for authorization, but proxies MUST NOT, and - instead MAY use the 407 response. The requirements for inclusion of - the Proxy-Authenticate, Proxy-Authorization, WWW-Authenticate, and - Authorization in the various messages is identical to [36]. - - Since SIP does not have the concept of a canonical root URL, the - notion of protections spaces are interpreted differently for SIP. The - realm is a protection domain for all SIP URIs with the same value for - the userinfo, host and port part of the SIP Request-URI. For example: - - - INVITE sip:alice.wonderland@example.com SIP/2.0 - WWW-Authenticate: Basic realm="business" - - - - - -Handley, et al. Standards Track [Page 113] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - and - - - INVITE sip:aw@example.com SIP/2.0 - WWW-Authenticate: Basic realm="business" - - - - define different protection realms according to this rule. - - When a UAC resubmits a request with its credentials after receiving a - 401 or 407 response, it MUST increment the CSeq header field as it - would normally do when sending an updated request. - -14.2 Basic Authentication - - The rules for basic authentication follow those defined in [36], but - with the words "origin server" replaced with "user agent server, - redirect server , or registrar". - - Since SIP URIs are not hierarchical, the paragraph in [36] that - states that "all paths at or deeper than the depth of the last - symbolic element in the path field of the Request-URI also are within - the protection space specified by the Basic realm value of the - current challenge" does not apply for SIP. SIP clients MAY - preemptively send the corresponding Authorization header with - requests for SIP URIs within the same protection realm (as defined - above) without receipt of another challenge from the server. - -14.3 Digest Authentication - - The rules for digest authentication follow those defined in [36], - with "HTTP 1.1" replaced by "SIP/2.0" in addition to the following - differences: - - 1. The URI included in the challenge has the following BNF: - - - URI = SIP-URL - - - 2. The BNF for digest-uri-value is: - - - digest-uri-value = Request-URI ; a defined in Section - 4.3 - - - - - -Handley, et al. Standards Track [Page 114] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - 3. The example procedure for choosing a nonce based on Etag - does not work for SIP. - - 4. The Authentication-Info and Proxy-Authentication-Info - fields are not used in SIP. - - 5. The text in [36] regarding cache operation does not apply - to SIP. - - 6. [36] requires that a server check that the URI in the - request line, and the URI included in the Authorization - header, point to the same resource. In a SIP context, these - two URI's may actually refer to different users, due to - forwarding at some proxy. Therefore, in SIP, a server MAY - check that the request-uri in the Authorization header - corresponds to a user that the server is willing to accept - forwarded or direct calls for. - -14.4 Proxy-Authentication - - The use of the Proxy-Authentication and Proxy-Authorization parallel - that as described in [36], with one difference. Proxies MUST NOT add - the Proxy-Authorization header. 407 responses MUST be forwarded - upstream towards the client following the procedures for any other - response. It is the client's responsibility to add the Proxy- - Authorization header containing credentials for the proxy which has - asked for authentication. - - - If a proxy were to resubmit a request with a Proxy- - Authorization header field, it would need to increment the - CSeq in the new request.

The server can then ascertain the origin of the request if it - has access to the public key, preferably signed by a trusted third - party. - - - -Handley, et al. Standards Track [Page 115] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -15.1.1 The WWW-Authenticate Response Header - - - - WWW-Authenticate = "WWW-Authenticate" ":" "pgp" pgp-challenge - pgp-challenge = * (";" pgp-params ) - pgp-params = realm | pgp-version | pgp-algorithm | nonce - realm = "realm" "=" realm-value - realm-value = quoted-string - pgp-version = "version" "=" - <"> digit *( "." digit ) *letter <"> - pgp-algorithm = "algorithm" "=" ( "md5" | "sha1" | token ) - nonce = "nonce" "=" nonce-value - nonce-value = quoted-string - - - - The meanings of the values of the parameters used above are as - follows: - - realm: A string to be displayed to users so they know which identity - to use. This string SHOULD contain at least the name of the host - performing the authentication and MAY additionally indicate the - collection of users who might have access. An example might be " - Users with call-out privileges ". - - pgp-algorithm: The value of this parameter indicates the PGP message - integrity check (MIC) to be used to produce the signature. If - this not present it is assumed to be "md5". The currently - defined values are "md5" for the MD5 checksum, and "sha1" for - the SHA.1 algorithm. - - pgp-version: The version of PGP that the client MUST use. Common - values are "2.6.2" and "5.0". The default is 5.0. - - nonce: A server-specified data string which should be uniquely - generated each time a 401 response is made. It is RECOMMENDED - that this string be base64 or hexadecimal data. Specifically, - since the string is passed in the header lines as a quoted - string, the double-quote character is not allowed. The contents - of the nonce are implementation dependent. The quality of the - implementation depends on a good choice. Since the nonce is used - only to prevent replay attacks and is signed, a time stamp in - units convenient to the server is sufficient. - - - - - - - -Handley, et al. Standards Track [Page 116] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Replay attacks within the duration of the call setup are of - limited interest, so that timestamps with a resolution of a - few seconds are often should be sufficient.

The signature MUST correspond to the From header of the - request unless the signed-by parameter is provided. - - pgp-signature: The PGP ASCII-armored signature [33], as it appears - between the "BEGIN PGP MESSAGE" and "END PGP MESSAGE" - delimiters, without the version indication. The signature is - included without any linebreaks. - - The signature is computed across the nonce (if present), request - method, request version and header fields following the Authorization - header and the message body, in the same order as they appear in the - message. The request method and version are prepended to the header - fields without any white space. The signature is computed across the - headers as sent, and the terminating CRLF. The CRLF following the - Authorization header is NOT included in the signature. - - A server MAY be configured not to generate nonces only if replay - attacks are not a concern. - - - - - -Handley, et al. Standards Track [Page 117] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - Not generating nonces avoids the additional set of request, - 401 response and possibly ACK messages and reduces delay by - one round-trip time. - - - Using the ASCII-armored version is about 25% less space- - efficient than including the binary signature, but it is - significantly easier for the receiver to piece together. - Versions of the PGP program always include the full - (compressed) signed text in their output unless ASCII- - armored mode ( -sta ) is specified. Typical signatures are - about 200 bytes long. -- The PGP signature mechanism allows - the client to simply pass the request to an external PGP - program. This relies on the requirement that proxy servers - are not allowed to reorder or change header fields. - - realm: The realm is copied from the corresponding WWW-Authenticate - header field parameter. - - signed-by: If and only if the request was not signed by the entity - listed in the From header, the signed-by header indicates the - name of the signing entity, expressed as a URI. - - Receivers of signed SIP messages SHOULD discard any end-to-end header - fields above the Authorization header, as they may have been - maliciously added en route by a proxy. - - Example: - - Authorization: pgp version="5.0" - ;realm="Your Startrek identity, please" - ;nonce="913082051" - ;signature="iQB1AwUBNNJiUaYBnHmiiQh1AQFYsgL/Wt3dk6TWK81/b0gcNDf - VAUGU4rhEBW972IPxFSOZ94L1qhCLInTPaqhHFw1cb3lB01rA0RhpV4t5yCdUt - SRYBSkOK29o5e1KlFeW23EzYPVUm2TlDAhbcjbMdfC+KLFX - =aIrx" - - - -15.2 PGP Encryption Scheme - - The PGP encryption scheme uses the following syntax: - - - - Encryption = "Encryption" ":" "pgp" pgp-eparams - pgp-eparams = 1# ( pgp-version | pgp-encoding ) - pgp-encoding = "encoding" "=" "ascii" | token - - - -Handley, et al.

Standards Track [Page 137] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -B.2 Setting SDP Values for Unicast - - If a session description from a caller contains a media stream which - is listed as send (receive) only, it means that the caller is only - willing to send (receive) this stream, not receive (send). The same - is true for the callee. - - For receive-only and send-or-receive streams, the port number and - address in the session description indicate where the media stream - should be sent to by the recipient of the session description, either - caller or callee. For send-only streams, the address and port number - have no significance and SHOULD be set to zero. - - The list of payload types for each media stream conveys two pieces of - information, namely the set of codecs that the caller or callee is - capable of sending or receiving, and the RTP payload type numbers - used to identify those codecs. For receive-only or send-and-receive - media streams, a caller SHOULD list all of the codecs it is capable - of supporting in the session description in an INVITE or ACK. For - send-only streams, the caller SHOULD indicate only those it wishes to - send for this session. For receive-only streams, the payload type - numbers indicate the value of the payload type field in RTP packets - the caller is expecting to receive for that codec type. For send-only - streams, the payload type numbers indicate the value of the payload - type field in RTP packets the caller is planning to send for that - codec type. For send-and-receive streams, the payload type numbers - indicate the value of the payload type field the caller expects to - both send and receive. - - If a media stream is listed as receive-only by the caller, the callee - lists, in the response, those codecs it intends to use from among the - ones listed in the request. If a media stream is listed as send-only - by the caller, the callee lists, in the response, those codecs it is - willing to receive among the ones listed in the the request. If the - media stream is listed as both send and receive, the callee lists - those codecs it is capable of sending or receiving among the ones - listed by the caller in the INVITE. The actual payload type numbers - in the callee's session description corresponding to a particular - codec MUST be the same as the caller's session description. - - If caller and callee have no media formats in common for a particular - stream, the callee MUST return a session description containing the - particular "m=" line, but with the port number set to zero, and no - payload types listed. - - If there are no media formats in common for all streams, the callee - SHOULD return a 400 response, with a 304 Warning header field. - - - - -Handley, et al. Standards Track [Page 138] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - -B.3 Multicast Operation - - The interpretation of send-only and receive-only for multicast media - sessions differs from that for unicast sessions. For multicast, - send-only means that the recipient of the session description (caller - or callee) SHOULD only send media streams to the address and port - indicated. Receive-only means that the recipient of the session - description SHOULD only receive media on the address and port - indicated. - - For multicast, receive and send multicast addresses are the same and - all parties use the same port numbers to receive media data. If the - session description provided by the caller is acceptable to the - callee, the callee can choose not to include a session description or - MAY echo the description in the response. - - A callee MAY, in the response, return a session description with some - of the payload types removed, or port numbers set to zero (but no - other value). This indicates to the caller that the callee does not - support the given stream or media types which were removed. A callee - MUST NOT change whether a given stream is send-only, receive-only, or - send-and-receive. - - If a callee does not support multicast at all, it SHOULD return a 400 - status response and include a 330 Warning. - -B.4 Delayed Media Streams - - In some cases, a caller may not know the set of media formats which - it can support at the time it would like to issue an invitation. This - is the case when the caller is actually a gateway to another protocol - which performs media format negotiation after call setup. When this - occurs, a caller MAY issue an INVITE with a session description that - contains no media lines. The callee SHOULD interpret this to mean - that the caller wishes to participate in a multimedia session - described by the session description, but that the media streams are - not yet known. The callee SHOULD return a session description - indicating the streams and media formats it is willing to support, - however. The caller MAY update the session description either in the - ACK request or in a re-INVITE at a later time, once the streams are - known. - -B.5 Putting Media Streams on Hold - - If a party in a call wants to put the other party "on hold", i.e., - request that it temporarily stops sending one or more media streams, - a party re-invites the other by sending an INVITE request with a - modified session description. The session description is the same as - - - -Handley, et al. Standards Track [Page 139] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - in the original invitation (or response), but the "c" destination - addresses for the media streams to be put on hold are set to zero - (0.0.0.0). - -B.6 Subject and SDP "s=" Line - - The SDP "s=" line and the SIP Subject header field have different - meanings when inviting to a multicast session. The session - description line describes the subject of the multicast session, - while the SIP Subject header field describes the reason for the - invitation. The example in Section 16.2 illustrates this point. For - invitations to two-party sessions, the SDP "s=" line MAY be left - empty. - -B.7 The SDP "o=" Line - - The "o=" line is not strictly necessary for two-party sessions, but - MUST be present to allow re-use of SDP-based tools. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Handley, et al.

Implementors will need to be familiar with the - notation in order to understand this specification. The augmented BNF - includes the following constructs: - - - - name = definition - - - The name of a rule is simply the name itself (without any enclosing - "<" and ">") and is separated from its definition by the equal "=" - character. White space is only significant in that indentation of - continuation lines is used to indicate a rule definition that spans - more than one line. Certain basic rules are in uppercase, such as SP, - LWS, HT, CRLF, DIGIT, ALPHA, etc. Angle brackets are used within - definitions whenever their presence will facilitate discerning the - use of rule names. - - - "literal" - - - Quotation marks surround literal text. Unless stated otherwise, the - text is case-insensitive. - - - rule1 | rule2 - - - Elements separated by a bar ("|") are alternatives, e.g., "yes | no" - will accept yes or no. - - - (rule1 rule2) - - - Elements enclosed in parentheses are treated as a single element. - Thus, "(elem (foo | bar) elem)" allows the token sequences "elem foo - elem" and "elem bar elem". - - - - - - - - -Handley, et al. Standards Track [Page 141] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - *rule - - - The character "*" preceding an element indicates repetition.

The full form is "# element" indicating at least - and at most elements, each separated by one or more commas (",") - and OPTIONAL linear white space (LWS). This makes the usual form of - lists very easy; a rule such as - - - - ( *LWS element *( *LWS "," *LWS element )) - - - can be shown as 1# element. Wherever this construct is used, null - elements are allowed, but do not contribute to the count of elements - present. That is, "(element), , (element)" is permitted, but counts - as only two elements. Therefore, where at least one element is - required, at least one non-null element MUST be present.

The steps listed below are used in place of the two - steps in section 1.4.2. - - If a step elicits no addresses, the client continues to the next - step. However if a step elicits one or more addresses, but no SIP - server at any of those addresses responds, then the client concludes - the server is down and doesn't continue on to the next step. - - When SRV records are to be used, the protocol to use when querying - for the SRV record is "sip". SRV records contain port numbers for - servers, in addition to IP addresses; the client always uses this - port number when contacting the SIP server. Otherwise, the port - number in the SIP URI is used, if present. If there is no port number - in the URI, the default port, 5060, is used. - - 1. If the host portion of the Request-URI is an IP address, - the client contacts the server at the given address. If the - host portion of the Request-URI is not an IP address, the - client proceeds to the next step. - - 2. The Request-URI is examined. If it contains an explicit - port number, the next two steps are skipped. - - 3. The Request-URI is examined. If it does not specify a - protocol (TCP or UDP), the client queries the name server - for SRV records for both UDP (if supported by the client) - and TCP (if supported by the client) SIP servers. The - format of these queries is defined in RFC 2052 [14]. The - results of the query or queries are merged together and - ordered based on priority. Then, the searching technique - outlined in RFC 2052 [14] is used to select servers in - order. If DNS doesn't return any records, the user goes to - the last step. Otherwise, the user attempts to contact - each server in the order listed. If no server is - contacted, the user gives up. - - 4. If the Request-URI specifies a protocol (TCP or UDP) that - is supported by the client, the client queries the name - server for SRV records for SIP servers of that protocol - type only. If the client does not support the protocol - specified in the Request-URI, it gives up. The searching - technique outlined in RFC 2052 [14] is used to select - servers from the DNS response in order. If DNS doesn't - - - - - -Handley, et al. Standards Track [Page 146] - -RFC 2543 SIP: Session Initiation Protocol March 1999 - - - return any records, the user goes to the last step. - Otherwise, the user attempts to contact each server in the - order listed. If no server is contacted, the user gives up. - - 5. The client queries the name server for address records for - the host portion of the Request-URI. If there were no - address records, the client stops, as it has been unable to - locate a server. By address record, we mean A RR's, AAAA - RR's, or their most modern equivalent. - - A client MAY cache a successful DNS query result. A successful query - is one which contained records in the answer, and a server was - contacted at one of the addresses from the answer. When the client - wishes to send a request to the same host, it starts the search as if - it had just received this answer from the name server. The server - uses the procedures specified in RFC1035 [15] regarding cache - invalidation when the time-to-live of the DNS result expires. If the - client does not find a SIP server among the addresses listed in the - cached answer, it starts the search at the beginning of the sequence - described above. - - For example, consider a client that wishes to send a SIP request. The - Request-URI for the destination is sip:user@company.com. The client - only supports UDP. It would follow these steps: - - 1. The host portion is not an IP address, so the client goes - to step 2 above. - - 2. The client does a DNS query of QNAME="sip.udp.company.com", - QCLASS=IN, QTYPE=SRV. Since it doesn't support TCP, it - omits the TCP query. There were no addresses in the DNS - response, so the client goes to the next step. - - 3. The client does a DNS query for A records for - "company.com". An address is found, so that client attempts - to contact a server at that address at port 5060. - - - - - - - - - - - - - - - -Handley, et al.

It is possible to add new headers to the SIP - * parser or extend the definition of existing ones. - * - * @section sip_parser_intro Parsing SIP Messages - * - * Sofia SIP parser follows @em recursive-descent principle. In other words, - * it is a program that descends the SIP syntax tree top-down recursively. - * (All syntax trees have root at top and they grow downwards.) - * - * In the case of SIP such a parser is very efficient. The parser can choose - * between different forms based on each token, as SIP syntax is carefully - * designed so that it requires only minimal scan-ahead. It is also easy to - * extend a recursive-descent parser via a standard API, unlike, for - * instance, a LALR parser generated by @em Bison. - * - * The abstract message module @b msg contains a high-level parser engine - * that drives the parsing process and invokes the SIP parser for each - * header. As there are no framing between SIP messages, the parser - * considers any received data, be it a UDP datagram or a TCP stream, as a - * @em message @em stream, which may consist of one or more SIP messages. - * The parser works by first separating stream into fragments, then building - * a complete message based on parsing result. After a message is completed, - * it can be given to the message stream customer (typically a protocol - * state machine). The parser continues processing the stream and feeding - * the messages to protocol engine until the end of the stream is reached. - * - * For each message, the parser starts by separating the first fragment, - * which is either a request or status line. After the first line has been - * processed, the parser engine continues by separating the headers - * one-by-one from the message. After the parser encounters an empty line - * separating the headers and the message body (payload), it invokes a - * function parsing the separator and payload fragment(s). When the message - * is complete, the parser can hand the message over to the protocol engine. - * Then it is ready to start again with first fragment of the next message. - * - * @image html sip-parser.gif Separating byte stream to messages - * @image latex sip-parser.eps Separating byte stream to messages - * - * When the parsing process has completed, the request or status line, each - * header, separator and the payload are all in their own fragment - * structure. The fragments form a dual-linked list known as @e fragment @e - * chain as shown in the above figure. The buffers for the message, the - * fragment chain, and a whole other stuff is held by the generic message - * type, #msg_t, defined in . The internal structure of #msg_t is - * known only within @b msg module and it is hidden from other modules. - * - * The abstract message module @b msg also drives the reverse process, - * invoking the encoding method of each fragment so that the whole outgoing - * SIP message is encoded properly. - * - * @section sip_header_struct SIP Header as a C struct - * - * Just separating headers from each other and from the message body is not - * usually enough. When a header contains structured data, the header - * contents should be converted to a form that is convenient to use from C - * programs. For that purpose, the message parser needs a special function - * for each individual header. The header-specific parsing function divides - * the contents of the header into semantically meaningful segments and - * stores the result in a header-specific structure. - * - * The parser passes the fragment contents to a parsing function immediately - * after it has separated a fragment from the message. The parsing function - * is defined by the @e header @e class. The header class is either - * determined by the fragment position (first line, separator line or - * payload), or it is found from the hash table using the header name as - * key. There is also a special header class for @e unknown headers, headers - * with a name that is not regocnized by the parser. - * - * For instance, the @From header has following syntax: - * - * @code - * from = ("From" | "f") ":" - * ( name-addr | addr-spec ) *( ";" addr-params ) - * name-addr = [ display-name ] "<" addr-spec ">" - * addr-spec = SIP-URL | URI - * display-name = *token | quoted-string - * addr-params = *( tag-param | generic-param ) - * tag-param = "tag" "=" ( token | quoted-string ) - * @endcode - * - * When a @From header is parsed, the header parser function sip_from_d() - * separates the @e display-name, @e addr-spec and each parameter in the @e - * addr-params list. The parsing result is assigned to a #sip_from_t - * structure, which is defined as follows: - * - * @code - * typedef struct sip_addr_s { - * sip_common_t a_common[1]; - * sip_unknown_t *a_next; - * char const *a_display; - * url_t a_url[1]; - * sip_param_t const *a_params; - * char const *a_tag; - * } sip_from_t; - * @endcode - * - * The string containing the @e display-name is put into the @c a_display - * field, the URL contents can be found in the @c a_url field, and the list - * of @e addr-params parameters is put in the @c a_params array. If there - * is a @e tag-param present, a pointer to the parameter value is assigned - * to @c a_tag field. - * - * @section sip_msg_struct SIP Message as a C struct - * - * It is not enough to represent a SIP message as a collection of headers - * following each other. The programmer also needs a convenient way to - * access certain headers at the SIP message level, for example, accessing - * directly the @From header instead of going through all headers and - * examining their name. The structured view to the SIP message is provided - * via a C struct with type #sip_t. - * - * In other words, a single message is represented by two types, first type - * (#msg_t) is private to the msg module and inaccessable by an application - * programmer, second (#sip_t) is a public structure containing the parsed - * headers. - * - * The #sip_t structure is defined as follows: - * @code - * typedef struct sip_s { - * msg_common_t sip_common[1]; // Used with recursive inclusion - * msg_pub_t *sip_next; // Ditto - * void *sip_user; // Application data - * unsigned sip_size; - * int sip_flags; - * - * sip_error_t *sip_error; // Erroneous headers - * - * sip_request_t *sip_request; // Request line - * sip_status_t *sip_status; // Status line - * - * sip_via_t *sip_via; // @Via (v) - * sip_route_t *sip_route; // @Route - * sip_record_route_t *sip_record_route; // @RecordRoute - * sip_max_forwards_t *sip_max_forwards; // @MaxForwards - * ... - * } sip_t; - * @endcode - * - * As you can see above, the public #sip_t structure contains the common - * header members that are also found in the beginning of a header - * structure. The @e sip_size indicates the size of the structure - the - * application can extend the parser and #sip_t structure beyond the - * original size. The @e sip_flags contains various flags used during the - * parsing and printing process. They are documented in the . These - * boilerplate members are followed by the pointers to various message - * elements and headers. - * - * @note Within the @b msg module, the public structure is known as - * #msg_pub_t. The application programmer can cast a #msg_t pointer to - * #sip_t with sip_object() function (or macro). - * - * - * @section sip_parsing_example Result of Parsing Process - * - * Let us now show how a simple message is parsed and presented to the - * applications. As an exampe, we choose a BYE message with only the - * mandatory fields included: - * @code - * BYE sip:joe@example.com SIP/2.0 - * Via: SIP/2.0/UDP sip.example.edu;branch=d7f2e89c.74a72681 - * Via: SIP/2.0/UDP pc104.example.edu:1030;maddr=110.213.33.19 - * From: Bobby Brown ;tag=77241a86 - * To: Joe User ;tag=7c6276c1 - * Call-ID: 4c4e911b@pc104.example.edu - * CSeq: 2 - * @endcode - * - * The figure below shows the layout of the BYE message above after parsing: - * - * @image html sip-parser2.gif BYE message and its representation in C - * @image latex sip-parser2.eps BYE message and its representation in C - * - * The leftmost box represents the message of type #msg_t. Next box from - * the left reprents the #sip_t structure, which contains pointers to a - * header objects. The next column contains the header objects. There is - * one header object for each message fragment. The rightmost box represents - * the I/O buffer used when the message was received. Note that the I/O - * buffer may be non-continous and composed of many separate memory areas. - * - * The message object has link to the public message structure (@a - * m_object), to the dual-linked fragment chain (@a m_frags) and to the I/O - * buffer (@a m_buffer). The public message header structure contains - * pointers to the headers according to their type. If there are multiple - * headers of the same type (like there are two @Via headers in the above - * message), the headers are put into a single-linked list. - * - * Each fragment has pointers to successing and preceding fragment. It also - * contains pointer to the corresponding data within the I/O buffer and its - * length. - * - * The main purpose of the fragment chain is to preserve the original order - * of the headers.

(@a X_common is an array of size - * 1, as it makes it easy to cast a header pointer to a pointer to - * msg_common_t.) - * - * The @a X_next is a pointer to another header (usually a pointer to - * structure of same type). If there are multiple headers with same name, - * like the two "Via" headers in the example above, the @a X_next is used to - * link the second header to the first. The fragment chain cannot be used - * for this purpose as the headers with same name are not necessarily - * adjacent in the parsed message. - * - * The rest of the fields contain the parsed or decoded representation of - * the header. In this case, it is a 32-bit integer followed by a list of - * parameters. The content of parameters is not parsed, they are just - * separated from each other and then stored in an dynamically allocated - * array of string pointers.
