- Did you consider capturing Ethernet traffic with Ethereal? All packets can be stored in a file. Then you can write scripts to check for a pattern in RTP stream. Note that Ethereal can also save 711 codec to a wav file that can be played on any PC.
- From what you described, to originating client it looks like the other side did auto-answer and immediately played RTP stream. If this is what you want to achieve you can use utility called pjsip (http://www.pjsip.org/). It has ability to automatically answer the call, play wav file and send DTMF digits + more.

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. Olivier. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
