[Freeswitch-users] Issue with WebRTC calls and Firefox 34-beta

We have noticed an issue on our BigBlueButton servers where people using
WebRTC and Firefox 34-beta can send their audio, but they aren't receiving
any audio back. It looks like Firefox is sending "c=IN IP4" in the
SDP, whereas in previous version of Firefox it would provide an IP address
on the c line. Is it possible that Freeswitch sees the in the SDP
and chooses to just receive only? We are seeing this problem on both
Windows and Mac machines.

The full client log can be found here, http://pastebin.com/8JX3PwEP, and
the output from fs_cli can be found here, http://pastebin.com/8nuF5e8e.

We use sip.js in the browser and I had originally posted the question to
their mailing list and the change in the "c" line was pointed out there. My
post can be found here,

Any assistance would be greatly appreciated.
