i tried the different ports and they work just set it to the port you want, that is a sip port.

One problem i'm having is i just setup a new PBX and for the life of me, i can't get the gateway to work with incoming calls, it just rings, then goes to a busy signal.

In the monitor, it doesn't show up, like the call isn't getting to the PBX System, but can make out going calls.

I wish as Resellers, we had some type of troubleshooting tools to know whats going on with the lines we have to manage.
