[Freeswitch-users] UDP vs UDP-NAT

Hi All I have a FS server in the cloud and have phones registering with FS from 2 different locations. From one location, the registration is UDP-NAT and just UDP from the second location. In the FS log, calls to the UDP connected phones work and they come up with an external IP address (sofia_glue.c:1232 sofia/internal/sip:1002@203.59.xxx.xxx:5060 sending invite) while the phones on the UDP-NAT site don't work because FS is trying to connect to them via the internal IP address (sofia_glue.c:1232 sofia/internal/sip:1000@192.168.0.111:5060 sending invite). The phones on both sites are behind a very standard modem with no port forwarding or NAT setting. What is wrong and how would I fix it? Thanks in advance. Dion.
