Hi!

I’m trying to make RTPEngine to work with calls Browser <-> SIP. Call From SIP to Browser working perfectly, but when calling to SIP from Browser, on 200 OK (sdp) I don’t receive ... a=rtcp-mux ... lines, but it was told to RTPEngine on reply_route to add this. And this line is mandatory for me, cause I don’t control JS softphone on other side

Reply route in a case of Browser->SIP call looks like

reply_route[REPLY_R] { … rtpengine_answer("internal external UDP/TLS/RTP/SAVPF ICE=force rtcp-mux-offer"); ... }

Also I’ve tried with rtcp-mux-accept but still no luck

You cannot "offer" rtcp-mux an in "answer".

I believe what you want is to use rtcp-mux-demux in the offer.
