Has anyone done this? I am trying to. The Summit can call the MBX extensions with no problem, but when I try to dial a summit extension from the MBX I get that line is busy? I have followed the tech bulletin precisely. I have been told that it is a port forwarding problem, but the IT guys are assuring me there is no port forwarding in the setup we are using because they are essentially on the same network. Any help or suggestions would be greatly appreciated.
