WOW.  Not supported.  That is not a good thing and don't understand why. 

So, if I remove those commands will we ....

1) Still be able to place and recieve calls through that gateway?

2) Still be able place and recieve calls throught that gateway if it is rebooted?

Question #2, is probably my biggest concern.

Thanks for the help!

To be more specific, this is not supported with MGCP because UCM does not support fractional T1 circuits. This is entirely possible if you use H.323 or SIP on the gateway instead of MGCP.

Your ability to place or receive calls will depend on the channel selection order and call volume. Either way, when you hit a channel that is not in service the call will likely fail. UCM (which has no idea of the limited timeslots) is controling the Q.931 signaling which includes the timeslot selection.

The link I posted explains how to busy out the channels so you don't hit a nonworking channel. But it clearly explains this won't be supported

For a workaround, use H.323 instead of MGCP if a fractional PRI is necessary.

As an alternative, busy-out the B-Channels that you are not using in Cisco CallManager by performing these steps:

Note: This procedure is not TAC-supported.

If you want TAC support you'll have to switch to H323.
