Hung Voice DS0s on 3640 T1/PRI running MGCP

I have a few hung DS0s (up for over 1 day) on my E&M trunks to the PBX which causes some user issues with UMAIL.

Is there any way to clear individual DS0s when you are only using a single DS0 group on your T1 controller?

Hardware 3640 T1/PRI

IOS 12.2(8)T5

Unfortunatly not, you will need a seperate ds0 group for each timeslot to do that.

Try upgrading to 12.2(13)T1, there have been several fixes for MGCP incorporated, unless you know that this is a telco issue for sure.

Thanks, that is what I thought. Inheritance stinks, a single DS0 group is not my preference.

I have been busing out the call and shutting the entire voice port down to correct this in the past. 12.2(13)T1 sounds like it might be in the future.

Thanks again.....
