Hello,
Good project!
As you spotted, SIPp doesn't check the RTP. Any RTP that comes in is just thrown away. What I am not sure is how you would actually do what you need. If the "tone" you are speaking about is a DTMF (or a serie of DTMFs), then you could add code in SIPp to retrieve the RTP, get the payload out of it, and use a DTMF detector to check that the DTMF(d) you expected is(are) part of the RTP stream (and if you do that, please let us know).
You might try other methods to "recognize" the RTP stream, but it really depends if you are in control of the RTP stream you get from the AS.
In any case, SIPp needs some modifications to retrieve and parse the RTP stream.
Hi Olivier,
Hello,
maybe you can help with a problem what i have. For a school project should i make a automatic testframework for SIP and RTP.
Good project!
The test is running in that waySIP client A call SIP client BSIP client give RINGING back - but a application server catch this message and give a new ringtone as RTP session back.My problem is now - i can use SIPp to check the whole SIP communication - but is it also possible to check maybe as pattern check is the right ring ton is comming back?If it is not possible via SIPp have you a hint/tip for me in which way i can 'automatic' (like in a script) testscenario?
