[sipx-users] Phones behind Nat/Pat firewall do not work

[Emery ville <emeryvilleberkley@xxxxxxxxx>]

Hello !

I have setup up my SIpxecs server on a public ip address and I have phones from different private networks trying to connect to the SIPxecs server.

But they are behind Nat and Pat firewalls. They manage to register themselves with the server but donot speak to themselves. There are no successful calls not even one between any phones. 

I tested the same phones worked percfectly when connected to the same lan(subnet) as the server before putting the server on the public IP address.

can some one help me with this problem.

Thanks,

Emery Konda
