Directory Numbers

Managing Directory Numbers

Directory numbers associate with devices such as phones, route points, CTI ports, and H.323 clients. Administrators manage directory numbers from the Directory Number Configuration and Route Plan Report windows in Cisco CallManager Administration. Use the Directory Number Configuration window to add, update, and remove directory numbers from a device, route point, or port. Use the Route Plan Report window to delete or update unassigned directory numbers from Cisco CallManager database.

Note Do not associate a directory number with a CTI route point or CTI port if the directory number is a member of a line group.

The Directory Number Configuration window contains two check boxes: Active and Update Directory Number of All Device Sharing this Line.

Active Check Box

The Active check box, which only displays for unassigned directory numbers, determines whether the directory number gets loaded and used by

Cisco CallManager. By checking the check box, the directory number gets loaded and used by Cisco CallManager. For example, the directory number belonged to an employee who left the company. The directory number had certain settings configured, like call forwarding to voice messaging. By leaving the directory number active, a call that is intended for the directory number will get forwarded. This eliminates the need to reconfigure another employee to have the same call forwarding options. If the check box is not checked, then the directory number will not get loaded by Cisco CallManager, resulting in settings configured for that DN to not be used (for example, call forward destinations) and callers will not get their call forwarded properly.

Update Directory Number of All Devices Sharing this Line

This check box determines whether a shared directory number gets updated to all devices sharing the number. By checking the check box, all devices sharing the directory number will receive the directory number change. By leaving the check box unchecked, only the current device displayed in the window gets the directory number changed and all other devices sharing the directory number remain unchanged.
