Hi all,
We are now doing some WEB-RTC interop tests with Chrome Browser, we test both 
Audio and Video, currently it looks like Chrome requires SAVPF and while using 
Video Chrome also sends a lot of video retransmissions depending on the control 
RTCP feedbacks, my question is
1. How common is the SAVPF and do you see a need for SBC's to overcome AVP\SAVP 
mismatches
2. Is there a way to work with Chrome\FireFox or any other browser without the 
feedback

Thanks

Ilan

It looks like 302 is the right one.  "RTP/SAVP" is the only media transport 
protocol (a profile of RTP), but the UA can't use it:

      302 Incompatible transport protocol: One or more transport
          protocols described in the session description are not
          available.
