There isn't one. I used the MBX to MBX for the MBX setup and Summit to Summit for the Summit set up. I have had Darren with Hoosier look at it, Toni from Vertical look at it and the IT people look at it. No one can figure it out. The systems can ping each other and I can talk Summit to MBX, but when I try to call from MBX to Summit I get a message saying that line is busy.
