Hi,<br>
<br>
I spent the past week experimenting with webrtc + asterisk 11.9.0-rc1 + opus/vb8 codec patch. This is interesting technology and I try to find out how to connect all the moving parts.<br>
<br>
Firefox:<br>
Neither sipml5 or jssip works with calls to asterisk, audio/video doesn't matter.<br>
WARNING[977][C-00000005] chan_sip.c: Rejecting secure audio stream without encryption details: audio 35684 RTP/SAVPF 109 0 8 101<br>
--> Asterisk sends "SIP/2.0 488 Not acceptable here"<br>
<br>
Chrome:<br>
I've tried both sipml5 and jssip softphones and they both work. Even video + confbridge works with some minor quirks (lost connections sometimes, I guess plain old nat issues).<br>
Just relaying audio+video with confbridge to a handful of participants seems to use quite a bit of cpu thought.<br>
<br>
Screen-share:<br>
This works, but Confbridge is not very happy about a channel with video (vp8) and not audio and is printing this 80 times a second:<br>
<br>
WARNING[8919][C-00000000] channel.c: Unable to find a codec translation path from (vp8) to (slin)<br>
WARNING[8919][C-00000000] chan_sip.c: Asked to transmit frame type slin, while native formats is (vp8) read/write = unknown/unknown<br>
WARNING[8919][C-00000000] channel.c: Don't know any of (vp8) formats<br>
<br>
<br>
How do you think about adding webrtc to a existing Asterisk/Kamailio environment? Do you use kamailio (websockets) as a front, a dedicated webrtc asterisk or something like webrtc2sip?<br>
<br>
How do you use / plan to implement webrtc in your environment?<br>
<br>
Any feedback is welcome. Thanks!<span class="HOEnZb"><font color="#888888"><br>
