</div>I assume your pipeline is something like:<br>
udpsrc -> rtpbin -> rtpXdepay ! Xdec ! sink<br>
<br>
When you get a new src pad on rtpbin with the payload type for<br>
telephone-event (ie DTMF) you can just put rtpdtmfdepay ! audiosink<br>
and it will play back the DTMF to you. It will also post a GstMessage on<br>
the GstBus telling you about the DTMF events so your application can<br>
react.<br>
<br>
You may be interested in Farstream which does that and more and is<br>
really centered about SIP/XMPP calls with GStreamer.<br>
