Hi all, I have a problem with RTP and NAT. The scenario is Hosted PBX and Natted phones (yealink): Phones (192.168.0.x) - NAT -> FS (public IP) When I call FS (for example an IVR) from a Phone, FS send the RTP to the private address (192.168.0.x) instead to the public NAT IP. The registration is ok: freeswitch@internal> sofia status profile tenant1.bs.dev.voip.clio.it reg 1 Registrations: ================================================================================================= Call-ID: 488014850@192.168.0.100 User: 202@tenant1.test.com Contact: "Test 202" <sip:202@192.168.0.100:5062;fs_nat=yes;fs_path=sip%3A202%40<NAT_IP>%3A37710> Agent: Yealink SIP-T20P 9.61.0.70 Status: Registered(UDP-NAT)(unknown) EXP(2012-06-06 19:01:55) EXPSECS(3232) Host: localhost.localdomain IP: <NAT_IP> Port: 37710 Auth-User: 202 Auth-Realm: tenant1.test.com MWI-Account: 202@tenant1.test.com How I can tell FS to send the RTP Packets to the right address? I think is needed a "comedia mode" like in Asterisk (or RTPProxy in openser)... Best regards,
