ccmPatternAlertGroupTable
A list of pattern used by the pattern type alert groups which are currently configured in the device. An entry is created if a configured alert group whose callHomeAlertGroupCapability has 'regularExpression'. An entry is deleted if the destination profile unsubscribes a pattern based alert group. Additional entry can also be created through ccmPatternAlertGroupStatus. Deleting all the entries for a destination profile alert group combination will result in profile unsubscribing to that alert group.
