Also, FS should be showing the call as anchored and with the IP of the sipx
server (the internal ip address).

So either you dont have sipx or the trunk configured properly, or you have a
strange firewall issue too.

there are many things probably wrong here, so here's a short list.


   1. sipx server should be behind NAT. It's IP address should be using stun
   or have the public address manually input.
   2. the itsp should NOT be doing nat traversal for you.
   3. stop using the iptables sip conntrack modules, they will not be of any
   help. just setup iptables to do symmetric nat.
   4. make sure your trunk say to use the public address for call setup.
