We have a WebRTC environment with Freeswitch and sipml5. The fact is that when a WebRTC extension receives a call, the SDP that sends Freeswitch not show the correct candidate: *======================================================================* *22d33210-d709-11e5-bdcd-078a69e08f30 Local SDP:* *22d33210-d709-11e5-bdcd-078a69e08f30 v=0* *22d33210-d709-11e5-bdcd-078a69e08f30 o=FreeSWITCH 1455870972 1455870973 IN IP4 X.X.X.X* *22d33210-d709-11e5-bdcd-078a69e08f30 s=FreeSWITCH* *22d33210-d709-11e5-bdcd-078a69e08f30 c=IN IP4 X.X.X.X* *======================================================================* Where X.X.X.X is the internal IP of Freeswitch beghind the NAT. Any idea?
