Hi, I am experimenting with mod_verto and using the demo to call to a conference on my server (logs on FreeSwitch seems ok generally), the issue is that I am not receiving/sending any audio (I would expect to hear moh at this point), I suspect this is because FreeSwitch sends an ice host candidate set to the internal ip instead of the external, here is the SDP: o=FreeSWITCH 1420641299 1420641300 IN IP4 10.245.43.195 s=FreeSWITCH c=IN IP4 10.245.43.195 t=0 0 a=msid-semantic: WMS Z2NxBScFjmpLZIlgYwYbxA7GyEbpC0Br m=audio 26060 RTP/SAVPF 111 126 a=rtpmap:111 opus/48000/2 a=fmtp:111 maxplaybackrate=48000; minptime=10 a=rtpmap:126 telephone-event/8000 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv a=fingerprint:sha-256 0D:BB:87:E0:B6:8A:AE:0D:32:3F:54:9F:36:FF:9B:89:28:AB:B4:17:BC:95:0D:2E:48:0C:33:30:78:52:5F:24 a=rtcp-mux a=rtcp:26060 IN IP4 10.245.43.195 a=ssrc:1435389439 cname:TfPkXSQ755IUEU1s a=ssrc:1435389439 msid:Z2NxBScFjmpLZIlgYwYbxA7GyEbpC0Br a0 a=ssrc:1435389439 mslabel:Z2NxBScFjmpLZIlgYwYbxA7GyEbpC0Br a=ssrc:1435389439 label:Z2NxBScFjmpLZIlgYwYbxA7GyEbpC0Bra0 a=ice-ufrag:hQuEgraFWcUo2lGL a=ice-pwd:qmWe5Cb0xJL2tDkAjF4pW5UJ a=candidate:0460306999 1 udp 659136 10.245.43.195 26060 typ host generation 0 Using Wireshark I see that the client is trying to send packets to 10.245.43.195 which obviously fails.. How can I fix this? Thanks, Adam
