[SR-Users] RTP Engine multiplexing and De-multiplexing

Hello, A call from a remote webrtc client is coming to (opensips+rtpengine). The media streams from the webrtc client is multiplexed. Can I use rtpengine to demultiplex the multiplexed streams and send it to other end as de-multiplexed SRTP traffic . This is because, the other end handle the srtp traffic only in demultiplxed manner. Also, the streams from the remote end is a separate SRTP and SRTCP traffic and the rtpengine has to add required ICE information to make the streams to go in a single port and it has to multiplex the streams and send it to webrtc client. It is mentioned that rtpengine can support multiplex/demultiplex. So, how can I configure rtpengine for this purpose from opensips? Your suggestions would be very helpful for us. Thanks. Riko
