Logging and voice gateways

[shikamarunara]

I'm trying to find more detail on a voice gateway's unregistration/registration that shows up in RTMT.  I've not done much in terms of logging, so this is new to me.  Can someone recommend a setting that will allow me to view an MGCP gateway's loss of registration - time and cause?  I'd like to be able to collect information for a 24 hour period if possible.

The call manager traces will give the time and cause of registration.

The document below will assist you with the trace collection.

You can also collect the debugs from the router using the following procedure:

Conf t

logging buffered

no logging console

debug mgcp packets

debug isdn q931

debug isdn q921

This will enable the logging buffer to run on your router.

When the problem occurs again can u do a

Conf t

No logging buffered

U all

Term length 0

Do sh log
