os.execute() returns [3
variables](f59e6a93c0/lauxlib.c (L286)).
Capture the 2nd (e.g. "exit") and 3rd (e.g. 0) in addition to the first
which would be merely `true` on success or `nil` on error.

<extension name="sound file tester">

<condition field="destination_number" expression="^((8|16|32|48)000)(.*)$">

<action application="lua" data="sound_test.lua $3 $1"/>

</condition>

Note the syntax of the destination number: <rate><type>
|
|
Rate can be 8000, 16000, 32000, or 48000
|
|
Type can be ivr, conference, voicemail, misc, digits, etc.
|
|
|
|
Using the extension listed above you could call it with mod_portaudio from fs_cli:
|
|
|
|
pa call 16000ivr
|
|
pa call 8000conference
|
|
pa call 32000conference
|
|
|
|
etc.
