> If this is a duplicate: sorry for the noise. I failed to find it on this versions.
> Test ) Call between two webrtc peers firefox 34 jssip client, asterisk playback audio before dial.
> On Playback(letters/asterisk); works great
> On Dial ;dial works for chan_sip or chan_pjsip. i only get this warnings
> {noformat}
> WARNING[10405][C-00000001]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect failed with: authentication failure 10
> WARNING[10405][C-00000001]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect failed with: authentication failure 110
> {noformat}
> Results
> - Audio ulaw works great.
> - Video VP8 not work on ast 13.1 ; in  ast 11 with patch VP8 pass.. video work with same versions of clients and configs,.
> - Signalling seems to be OK. compare with ast11 
> - This behavior is the same for chan_sip and chan_pjsip.
> - Curious thing if you call from softphones (linphone) that support udp vp8 to web browser , linphone could see video from web browser but web browser couldn't see video from linphone, seems like asterisk is changing something on VP8 streams when webrtc peer is involve.
> When you call between WebRTC endpoins Asterisk 13.1 is sending media (audio, video) to both legs of the call but video part not work , Firefox/chrome Video debug said "Received incomplete frame timestamp" and "Decoder error: -1"
