--[[ Use a dialplan entry like this:
<extension name="sound file tester">
<condition field="destination_number" expression="^((8|16|32|48)000)(.*)$">
<action application="lua" data="sound_test.lua $3 $1"/>
<action application="hangup"/>
</condition>
</extension>
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.
