It is the right thing to do to turn on dtls.  As far as how it should be handled in jsssip, you will have to talk to them about that.  I don't think we plan at this point to support webrtc without dtls as everything I have seen says it will be required by the browsers at some point anyways.

I confirm that the changes made by Iwan worked and gave me audio. Thanks, Iwan. 

But now the question is that is it a hack on the js side or is it the right thing to do? And is it going to be merged into the JsSIP core?

Thanks,

Henry

Henry,
I can make it jssip demo works by modify this line

  this.peerConnection = new
JsSIP.WebRTC.RTCPeerConnection({'iceServers': servers}, constraints);

into

constraints["optional"] = [];
constraints["optional"].push({'DtlsSrtpKeyAgreement': 'true'});

this.peerConnection = new
JsSIP.WebRTC.RTCPeerConnection({'iceServers': servers}, constraints);
