In CUCM when a Directory Number becomes unassigned (not associated to a device) the DN gets an "Active" checkbox to determine if the line is active or inactive.
A client has unassigned Directory Numbers that are active and associated as call forwards etc, and would like the option to exclude those "Active" Directory Numbers from DN Pools when the "Include Unassigned DN" is enabled.
The feature already exists. Active unassigned numbers are automatically excluded from DN pools.
Client is Broadridge Financial Solutions. Zendesk ticket #43315
