So using a syntax like
../sipp -sn uac SERVER_IP -s DESTINATION_NUMBER -ap AUTH_PASSWORD -aa -m 1 -l 1 -d 10000
I am able to initiate a sip call. What I want to achieve is, after the callee picks the call, play a .wav file and terminate the call after the file is finished playing.
I want to achieve this using the command line arguments. Has someone done this before?
Answer
The latest SIPp version (3.4) does now support direct RTP streaming, from a correctly-encoded WAV file.
You'll want to create a custom scenario file (using the -sd uac option to dump out the sample UAC scenario as a starting point) and add <action><exec rtp_stream="file.wav" /></action> inside the <recv response="200"></recv> XML block, to trigger that WAV file to be played over RTP when the 200 OK is received.
http://sipp.sourceforge.net/doc/reference.html#Media%2FRTP+commands has more details on setting this up (such as looping or non-PCMA payload types).
(I'm the current maintainer of SIPp.)
