Directory Numbers

OL-7135-01

if you want to assign a specific directory number to a phone or if you plan to

implement authentication or encryption, as described in Cisco CallManager

Security Guide 4.1.

Cisco CallManager automatically disables auto-registration if you configure the

clusterwide security mode for authentication and encryption through the

Cisco CTL client.

If you do not use auto-registration, you must manually add phones to the

Cisco CallManager database or use the Bulk Administration Tool (BAT). BAT, a

plug-in application, enables system administrators to perform batch add, modify,

and delete operations on large numbers of Cisco IP Phones. Refer to the Bulk

Administration Tool Guide for Cisco CallManager for detailed instructions on

using BAT.

Using Directory Number Configuration in Cisco CallManager Administration,

you can configure and modify directory numbers (lines) that are assigned to

phones. Keep in mind, however, that directory numbers do not always associate

with devices (see the

"Managing Directory Numbers" section on page

You can configure up to 200 calls for a line on a device in a cluster, with the

limiting factor being the device. As you configure the number of calls for one line,

the calls available for another line decrease. Cisco IP Phones that support the

multicall display (such as a Cisco IP Phone 7960) support up to 200 calls per DN

and 2 calls per DN for non-multicall display devices (such as Cisco IP Phone

7905).

The Cisco IP Phone displays the following information about each line:

Unique call identifier (from 1 to 200). This identifier is consistent across all

•

multicall display devices that have a shared line appearance.

Call select status, an icon which shows the state of the currently selected call.

•

Call information such as calling party or called party.

•

Call state icon such as connected or hold.

Duration of a call
