I'm testing with a normal rtpproxy configuration. BTW udp -> udp work perfectly. > > Again, put here the ngrep for registration and a call to see if something is > wrong with signaling.

I tried the default cfg enabling both NAT and RTPproxy, but seems that kamailio doesn't reuse TCP ports. Anyway, this is a call from UDP (512) -> TCP (526) both behind the same NAT, from kamailio point of view [root@proxy ~]# kamctl ul show 526 Contact:: <sip:526@94.94.X.X:1238;transport=TCP;ob>;q=;expires=537;flags=0x0;cflags=0x40;state=0;socket=<tcp:178.79.x.x:5060>;methods=0x1FDF;received=<sip:94.94.X.X:61922;transport=TCP>;user_agent=<DICE Smartphone 1.0/iPhone>;reg-id=0 [root@proxy ~]# kamctl ul show 512 Contact:: <sip:512@94.94.X.X:5060>;q=;expires=32;flags=0x0;cflags=0x40;state=0;socket=<udp:178.79.x.x:5060>;methods=0xFFFFFFFF;received=<sip:94.94.X.X:1025>;user_agent=<DICE 1.8.20.1>;reg-id=0 [root@proxy ~]# U 94.94.X.X:1025 -> 178.79.x.x:5060 INVITE sip:526@test.domain:5060 SIP/2.0.
