How to delete unassigned directory numbers in Cisco CallManager 4.0

Core Issue

Cisco CallManager 4.0 has a new concept of Unassigned Distinguished Names . When a phone or a line is deleted, the associated DNs are not removed from Structured Query Language (SQL) as in the past. To see a list of directory numbers that are not associated with phones, use the Route Plan Report menu option.

Unassigned DNs allow customers to continue forwarding to voice mail or another destination for DNs that are no longer assigned to devices. This happens often when employees are reassigned or terminated.


DNs associate with devices such as phones, route points, Computer Telephony Integration (CTI) ports,and H.323 clients. Administrators manage directory numbers from the   Directory Number Configuration and Route Plan Report windows in Cisco CallManager    Administration.  To delete the directory number from the database using the Route Plan Report window, perform these steps:

  1. Choose Route Plan > Route Plan Report.

    The Route Plan Report window displays. Use the three drop-down list boxes  to specify a route plan report that lists all unassigned DNs.

  2. These are the three ways to delete directory numbers: 

    • Click the directory number that you want to delete. When the directory number configuration window displays, click Delete.
    • Check the check box next to the directory number that you want to delete. Click Delete Selected.
    • To delete all found unassigned directory numbers, click Delete all Found Items.

    A warning message verifies that you want to delete the directory number.

  3. To delete the directory number, click OK. To cancel the delete request, click Cancel.

Note: Prior to release 4.0, directory numbers were automatically deleted when    a device was deleted. Because line group support is a feature of release 4.0, keeping unassigned DNs is a requirement.

For more information on unassigned DNs, refer to the Deleting Unassigned Directory Numbers section of Route Plan Report.
