2811 drops calls when connection to CCM Drops

Got an issue with 2811's configured with PVDM's dropping calls if the link to the CCM goes down. We use ISDN dialback for a failed link, but still loose all calls while the ISDN dialup is occuring.

We've been running 2651XM's with an AIM-Voice-30 and found that if the link to the CCM servers was lost, calls in progress would remain up, but new calls would be unavailable until the ISDN dialback was operational.

Is there something in the 2811 config that specifies not to drop calls? Is there any particular config that should be used?

Is this a MGCP or H323 gateway!

MGCP on both the 2651 with no issues and the 2811 with issues.
