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

WARNING[10405][C-00000001]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect failed with: authentication failure 10

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.

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"
