<div dir="ltr">Hi All,
<div><br></div>
<div>I've been working with a company who utilise WebRTC using Asterisk behind Kamailio to connect browser users and their SIP infrastructure and just came across an issue making/receiving calls in Chrome Canary and Chrome Dev.</div>
<div><br></div>
<div>Long story short; the issue is that rtcp-mux has now been set as required in Chrome's WebRTC stack - <a href="https://groups.google.com/forum/#!topic/discuss-webrtc/eM57DEy89MY" target="_blank">https://groups.google.com/fo<wbr>rum/#!topic/discuss-webrtc/eM5<wbr>7DEy89MY</a></div>
<div><br></div>
<div>For now; there is a workaround of being able to pass in a flag to the RTCPeerConnection call to get the old "negotiate" behaviour and I'm talking to the Chrome team to find out how long this flag will be around for.</div>
<div><br></div>
<div>I've been told that Asterisk doesn't support rtcp-mux as of today and so I'm raising the issue here. It seems - if Asterisk wants to support WebRTC long term; it will need to support rtcp-mux - I quote Sean Bright from a conversation we had in IRC where he said it was "non-trivial" to support.</div>
<div><br></div>
<div>I don't know more than this and I don't mean to say something is difficult to fix when I honestly don't know the effort levels in order to fix this. So I'm raising this here for a conversation.</div>
<div><br></div>
<div>I will be testing the client side flag fix in jssip in a moment and then writing up a blog post about it if it does indeed fix the issue, at least temporarily while the flag is available.</div>
<div><br></div>
<div>Dan</div>
