wrong interface after early announcement #72

Open MarcoHierl opened 6 years ago

MarcoHierl commented 6 years ago

Dear all, I receive a call from an external IP on my external interface. I make rtpproxy_offer (frocei) to get an early announcement from an announcement server with an internal IP (10.*.*.*). Afterwards I make a 2nd rtpproxy_offer (frocee) for the INVITE to the callee with an external IP. But the SDP in the 2nd INVITE points out my internal IP. thanks and best regards Marco

Hi again, maybe I need to mention that the external IP of my machine is 62.155.10.4. This one I expect to get from rtp proxy after the 2nd "offer". But I get the internal 10.249.152.6: Dec 20 13:13:37 rtp-dtag-hh rtpproxy[20298]: DBUG:GLOBAL:rtpc_doreply: sending reply "20306 10.249.152.6\n" I tried to use flags "a", "s" and "w", but it did't work out. Any help is very appreciated. Thanks and best regards Marco
