Hi Gents, I have added dtmf detection to my tdm audio device. I have used spandsp tdmf detection which appears to work fine for my application. Now I am wondering what would be the best way to pass the dialed extension from my audio_device to the pjsua application layer. The spandsp dtmf allows an on_dtmf() callback to be hooked so we can have notification on each digit. Any comments will be appreciated.

Thanks to the help from the this mailing list I have managed to move the task up to the point I have clean audio between my analog phone and a sip client analog_phone - pjsip <---> (Asterisk SIP server) <---> SIP client My SLIC doesn?t have built in DTMF detection. I just read that pjmedia doesn?t support inband DTMF detection. Can you please confirm/refuse that ? If DTMF doesn?t supported I am willing to borrow the inband DTMF detection from Asterisk or some other open implementation and put it in pjmedia. Do you see benefits for the project? As I am very new to pjsip I am not sure which will be the native way to integrate such a detector in pjsip. Is someone willing to advice me on the best way to put DTMF detection in the pjmedia?
