Hi Varun, Sorry I was probably not explained well. I am trying to use pjsip with an analog phone connected to it. As soon as analog phone pickup and dial an extension I have to recognize the dtmf generated by the phone and do a sip call using pjsip stack to an external SIP server. Thanks Dimitar From: varun ahluwalia Sent: Tuesday, April 7, 2015 16:01 To: pjsip list Subject: Re: Inband DTMF Hi Dimitar, In which scenario do you expect the SIP client to process Incoming DTMF? DTMFs are generally used in outward direction (from client to Server). Can you change the mode to SIP INFO for DTMF at Asterisk and try? PJ supports INFO.. So, you might be able to detect Inward DTMF as well. Or are you trying to use PJ at the Server itself? regards, On Mon, Apr 6, 2015 at 5:27 PM, <dpn at switchvoice.com> wrote: 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?
