Hi,
There finally was some progress on the ice-lite issue in Firefox over the last week or two (after the bug report got stuck for months), so I'd expect Firefox nightly to properly work with ice-lice in a couple of days or so.

Hi Richard!
Just have tried an outgoing call to Chrome and Opera and it works fine. Thank you for the clarification regarding ICE! Dump files and rtp logs (Firefox, Chrome) I've sent to your email.
My little investigation brings the following :
browsers (Firefox, Chrome and Opera) don't use "a=ice-lite" in their SDP;
Chrome and Opera take the role of ICE-CONTROLLING and provide
USE-CANDIDATE for the ICE-Lite peer (mediaproxy) for both "offer" and "answer" cases;
- Firefox takes the role of ICE-CONTROLLING and provide USE-CANDIDATE in
case of the "offer" while it takes the role of ICE-CONTROLLED during the "answer"; /means no media from WebRTC UA in the latter case/
Some other remarks.
During the call from Fire I saw a lot of "SRTP output wanted, but no crypto suite was negotiated" messages from rtpengine. However DTLS is finally was established. Is that one more issue of Firefox?
Looking in STUN section of the dump files I wonder why Chrome use more than 10 binding request (USE-CANDIDATE) for each candidate while Mozilla does it just once.
regards, Alexey

There's nothing wrong with the SDP bodies that I can see. I recall that Firefox had or still has a problem with ICE role switching when ice-lite is offered. It never completes ICE negotiation (never sends an STUN packet with "use candidate") and so never starts DTLS handshake. You can confirm that by doing a packet capture including the RTP ports and inspecting the STUN packets. Chrome shouldn't have that problem though, perhaps do another test run with it? You can send those capture files to me if you'd like me to have a look.
