The following new software features are supported by the Cisco MC3810 for Cisco IOS Release 
12.2(2) XA:

Before the call admission control feature, gateways did not have a mechanism to gracefully prevent calls 
from entering when certain resources were not available to process the call. This causes the new call to 
fail with unreported behavior, and could potentially cause the calls that are in progress to have quality 
related problems.

This feature set provides the ability to support resource-based call admission control processes. These 
resources include system resources such as CPU, memory, and call volume, and interface resources such 
as call volume.
