Hi Alex, Yes its a specific application which requires te dtmf tone. i reaceive the dtmf from the router which identifies the tone from an analog interface. and sends the RFC 2833 to my application which is built on pjsip. I should get both now, the call back on the rfc 2833 and the actual tone that came from the analog equipment should be on the RTP. i want to record the audio with in a spefic key in duration of DTMFs from the analog side and write the entire audio within that duration to a wavefile. another application reads this wave file and gives me a specific value called stregth of the signal based on the amplitude of the signal. the same stuff works with an xlite phone or a linksys phone but now with pjsip. I need help on this and thats immediate. Ravi On Sun, Mar 21, 2010 at 6:00 AM, alex vishnev <alex9134 at gmail.com> wrote: > Ravi > > > I think we are talking about 2 different things.
