[OpenSIPS-Users] MediaProxy do not add Relay Candidate

Sun Dec 4 13:21:18 CET 2011

Finally I debug opensips, set breakpoint on use_media_proxy, found 
MediaProxy Module don't find ice parameter(such as has_ice, 
first_ice_candidate is not set). when I set ice param at the end of SDP, 
then Relay works!

ie:

v=0
o=- 3531651689 3531651689 IN IP4 114.246.xxx.xxx
s=linphone
c=IN IP4 114.246.xxx.xxx
t=0 0
m=audio 46909 RTP/AVP 0 96
a=rtpmap:0 PCMU/8000
a=rtpmap:96 telephone-event/8000
a=fmtp:96 0-15
a=sendrecv
a=ice-ufrag:18e62b54
a=ice-pwd:5cf02fda
a=candidate:Sa00020f 1 UDP 1862270975 114.246.xxx.xxx 46909 typ srflx raddr 10.0.2.15 rport 26836
a=candidate:Ha00020f 1 UDP 1694498815 10.0.2.15 26836 typ host
