Jay Jideliov commented on ASTERISK-23190:
-----------------------------------------

The issue has been fixed by manually going through all of the patches. I am attaching a combined 11.7 patch that enables WSS calls (DTLS/SRTP).

>      Security Level: None

> This is a follow-up ticket that relates to asterisk patched as described here: 
> Patch 1: ASTERISK-22961
> Patch 2: ASTERISK-21930
> After getting SRTP and WSS to work, we are still experiencing the lack of sound. We believe that this is another bug that has to be fixed to obtain a fully working WebRTC secure deployment (WSS) functioning on Chrome/Firefox/Opera, finally pushing it to a normal (functioning) state.
> 1) We had a clean 11.7 to which we have added the patch from ASTERISK-22961
> 2) This got us to a working WebRTC on Chrome/Firefox over WS
> 3) Then, we have applied the patch from ASTERISK-21930 to get WSS to work
> 4) A call was established using SIPML5 over WSS, however, no sound was flowing
> The only error in console is: SetRemoteDescription failed: Called with an SDP without ice-ufrag and ice-pwd. (although we believe that this has nothing to do with the issue).
> The CLI gives us this:
