Hello, I'm working with start_dtmf in order to transcode inband DTMF to RTP-Event. That's working fine but I'm wondering how could I check the B-leg SDP to match if there's or not "telephone-event" to do it only if require. That would also allow me to do RFC2833 to inband from A-leg to B-leg. I can easily check ${switch_r_sdp} for A-leg, but I can't figure out how to check 200 OK SDP and update the DTMF behaviour accordingly. Any idea? Thank you.

Are you talking about the following case? A makes a call to FS, and FS sends it to B as below. A ----> FS ----> B And in 200 from B, there is no telephone-event in SDP, and you need to convert DTMF from A in telephone-event to in-band audio to B. /Kaiduan On Wednesday, May 12, 2021, 11:29:12 a.m. EDT, Igor Potjevlesh <igor.potjevlesch@gmail.com> wrote: <!--#yiv1649628383 _filtered {} _filtered {}#yiv1649628383 #yiv1649628383 p.yiv1649628383MsoNormal, #yiv1649628383 li.yiv1649628383MsoNormal, #yiv1649628383 div.yiv1649628383MsoNormal {margin:0cm;font-size:11.0pt;font-family:"Calibri", sans-serif;}#yiv1649628383 span.yiv1649628383EmailStyle17 {font-family:"Calibri", sans-serif;color:windowtext;}#yiv1649628383 .yiv1649628383MsoChpDefault {} _filtered {}#yiv1649628383 div.yiv1649628383WordSection1 {}--> Hello, I'm working with start_dtmf in order to transcode inband DTMF to RTP-Event.
