Hi Brian

Am using 1.2.13+git~20130919T142456Z~6afb17a138

It is strange because in the debug CLI it constructs some SDP (for sending back 183 early media) which looks sane:

2014-01-28 14:38:05.000169 [DEBUG] mod_sofia.c:2876 Ring SDP:
v=0
o=FreeSWITCH 1390904357 1390904358 IN IP4 95.211.119.213
s=FreeSWITCH
c=IN IP4 95.211.119.213
t=0 0
m=audio 15528 RTP/AVP 111 101
a=rtpmap:111 opus/48000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=ptime:20
a=sendrecv

then the SDP sent out is different (port is now 0 and opus is now mapped to 100). This is from the ngrep trace:

.
v=0.
o=FreeSWITCH 1390904357 1390904358 IN IP4 95.211.119.213.
s=FreeSWITCH.
c=IN IP4 95.211.119.213.
t=0 0.
m=audio 0 RTP/AVP 100 101.
a=rtpmap:100 opus/48000.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-16.
m=video 0 RTP/AVP 19.

It works fine out of the box with WebRTC; you just allow OPUS on your codec list.  Are you having a negotiation failure? What rev of FreeSWITCH are you using?
