Can you check about:webrtc and send me the connection log, the
table of ICE stats, and the SDP?
Best regards,

I am using JsSIP on Firefox 38 and making calls via Kamailio SIP proxy and
media relay. With an inbound call (offer to WebRTC) coming via Kamailio, I see
ICE fail in browser console (JsSIP defaults to terminate the call if it sees
iceconnetionstate === 'fail' in oniceconnectionstatechange event).
Kamailio modifies the candidate lines in SDP offer, inserting its IP/port, and
they appear to Firefox end like this:
a=candidate:iwIBAJAL55e3Lvye 2 UDP 2130706430 <Kamilio IP> <Kamailio port> typ
host
Kamailio also adds this: a=ice-lite. I believe this means it will simply
respond to STUN requests, but not much more. I see that, on browser side, ICE
checks between its local ip to the Kamailio ip fail, but it succeeds between
server reflexive IP and Kamailio IP. So there is always 2 fails and 2 successes
(for audio and video).
If ICE partially succeeded, why does it seem to fail completely?
