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

[Dave Goodwin]

It actually may depend on what type of IP endpoint is calling the gateway.
With the gateway in MGCP mode, I have had the best overall compatibility
results when I configured the gateway to support RFC2833 and allow CUCM to
negotiate that. I usually keep the Type of DTMF Relay in CUCM to its
default value, and these are the commands I typically add, as I've never
seen them on by default nor do they seem to get added during the
auto-configuration from CUCM. Make sure to re-register the gateway to CUCM
after the changes. Your mileage may vary, but perhaps this will help.

mgcp rtp payload-type nte 101
mgcp package-capability fm-package
mgcp dtmf-relay voip codec all mode nte-ca
