[SR-Users] Mozilla Firefox + SIP Phone voice not established

Fri Oct 17 10:24:05 CEST 2014

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?
