Adding Phones with Auto-Registration

You can add phones with auto-registration without first gathering MACaddresses

from the phones.

Note Cisco recommends you use auto-registration to add less than 100 phones to your

network. To add more than 100 phones to your network, use the Bulk

Administration Tool (BAT). See the “Adding Phones with BAT” section on

page 2-16.

When auto-registration is enabled, CiscoUnified CallManager begins the

automatic startup process to obtain a directory number. During auto-registration,

Cisco Unified CallManager automatically assigns the next available sequential

directory number to the phone.

When you use this method, Cisco UnifiedCallManager automatically assigns

directory numbers to new phones as they register with CiscoUnified

CallManager.

You can use auto-registration to quickly enter phones into the

Cisco Unified CallManager database. You can then modify any settings, such as

the directory numbers, from CiscoUnified CallManager. Additionally, you can

move auto-registered phones to new locations and assign them to different device

pools without affecting their directory numbers.

Auto-registration is disabled by default.

For information about enabling and configuring auto-registration, refer to Cisco

UnifiedCallManager Administration Guide.

Note When you configure the cluster for mixed mode through the Cisco CTL client,

auto-registration is automatically disabled. When you configure the cluster for

non-secure mode through the Cisco CTL client, auto-registration is automatically

enabled.
