You was right, in 200 OK was set RTP/AVPF (and in offer RTP/SAVPF) and I did nothing with this mismatch. Now, playing around with flags for RTPengine, I have one questions for such case: Browser send INVITE with RTP/SAVPF, RTPengine send forward to client with RTP/AVPF When comes 200 OK with RTP/AVPF RTPengine change it to RTP/SAVPF and forward to browser. In this case I got in browser log: setRemoteDescription() | error: +5ms Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer. Does this configuration has to work, or on the whole path has to be only one profile RTP/AVPF or RTP/SAVPF? Thanks in advance!
