Hi

I have configured latest Kamailio 4.2.0 + Rtpengine 3.3.0.0+0~mr3.6.0.0

There are 2 SIP clients. Once client is registered as WebRTC client from Mozilla Firefox browser 29.0.1 and second SIP client is desktop SIP phone - PortGo Softphone (portsip.com) When I am trying to call softphone from Firefox, call is getting established, where as voice is not established. RTP is not flowing between Browser and Softphone. Same is working with Google Chrome.

Following command is used for negotiation rtpengine_manage("replace-origin replace-session-connection ICE=force");

Log is as follows

Another issue is for reverse scenario. Softphone calling WebRTC client. This option does not work with Mozilla & Chrome.

Please help. Am I missing something? Do I need to modify configuration to make this work?
