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.
