Hi All I'm using rtpengine to in my implementation of webrtc. In my client side browser I have used following code snippet to configure stun/turn servers to identify ice candidates and turn fall back. var pcConfig = {"iceServers": [ {'url': 'turn:52.6.57.126:3478?transport=tcp'}] <http://52.6.57.126:3478?transport=tcp'}]>}; peerConn = new PeerConnection(pcConfig); Am using rfc 5766 turn server http://code.google.com/p/rfc5766-turn-server/ As long as stun is working my webrtc flow works fine. I wanted to know how rtpengine support the turn fallback, is there any configuration required in this case.
