[cisco-voip] Take incoming MGCP gateway out of production but keep up for testing?

[Fuermann, Jason]

Be careful of this. When we busy out a channel and receive a call from ATT, ATT considers the line busy and sends the busy signal to the calling party.

your first challenge is that the carrier controls the inbound routing.  if CM brings up the d-ch and b-ch the carrier will present calls inbound on that circuit.  Best case scenario your carrier would switch the order of your circuits to make another circuit higher in the inbound hunt group.

otherwise you can reduce impact. use cm service parameter to busy out all but 1 b-ch on that ds1.  This will allows 1 call inbound/outbound.   Carrier will see the other 22 b-ch as out of service and hunt to the next circuit.

Is there a simple way to take a gateway out of service in CallManager (or router) that is MGCP?  It is on 3825 router with 3 other gateways.

Yesterday had an issue with a DID circuit bouncing every five minutes up/down.  We wanted to take it out of service for DID calls, but still allow carrier to have it up for testing.  We did a shut on the interface 0/0/0:23, shutting down the signaling port for ISDN - which really shuts down the whole circuit, but a few moments later it came back online because CallManager controls the circuit and expected it online.

Shutting down the controller for the interface doesn't allow the carrier to test all the way through.

Any help would be appreciated.  Jacquie Manick
