[cisco-voip] Limiting outbound ISDN calls to a limited set of channels?

[Buchanan, James]

There is a way to put certain channels in maintenance mode, which will prevent UCM from using the channels, but will not prevent CallManager from reconfiguring them as full. What you could do is use the "ccm-manager config" command in the IOS router to do the initial config, then remove "ccm-manager config" which will keep CallManager from reconfiguring the T1s every time.

It is not supported however to use a partial PRI, and you can mix MGCP and H323 on the same gateway.

Can I mix H.323 and MGCP on the same gateway?
