[cisco-voip] FXO port to Viking C-1000B door entry controller

[Kevin]

Hi,

I was wondering if a solution was found.

I have a similar issue. We have a Viking gate opener that was connected to a Nortel Option 11c analog port. We have migrated to a CUCM. The local analog port is now an FXS port on a Cisco 4331 router using MGCP. The call box at the gate works in that I can call from the call box to a Cisco IP phone and a two way connection works. But when the code is entered on the IP phone to open the gate, the call drops and the gate does not open.

Thanks in advance.
