Sifting through hundreds of posts, I have not seen a post applying to this configurations.
I have two * servers. One is on a local network and the other is on an external network. The PCs on the local network are behind a NAT (the * server is not). I have no problems at all with my local server. However when I try to use the outside server, I can make and recieve calls, but once the session is open there is no voice. I assume that the asterisk configuration is okay, and the problem is with NAT or sjphone. I would like some advice.
The router/nat is a Belkin wireless box.
