Yeah it is behind a firewall of some kind. both places have a VPN router link together how it works i have no clue.
But at least now it is connected just got to figure out the one way audio problem and the disconnection of calls. I made a new post for it.
I am surprised that your calls on that gateway have worked before. I can’t imagine.
When it was here on the same network. Yes calls was working in and out but when i moved it to the other place i haven’t done anything with it or hooked it up into yesterday but that is when i had the problems with it.
In summary, your gateway stopped working because you moved it to a different network and didn’t update the host IP address in the trunk peer settings. The outbound route CallerID solution also works.
