Autoregistration Phone Addition
By enabling auto-registration before you begin installing phones, you can:
•
Add phones without first gathering MAC addresses from the phones.
•
Automatically add a Cisco Unified IP Phone to the Cisco Unified Communications Manager database
when you physically connect the phone to your IP telephony network. During auto-registration,
Cisco Unified Communications Manager assigns the next available sequential directory number to the
phone.
•
Quickly enter phones into the Cisco Unified Communications Manager database and modify any settings,
such as the directory numbers, from Cisco Unified Communications Manager.
•
Move auto-registered phones to new locations and assign them to different device pools without affecting
their directory numbers.
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).
Note
Auto-registration is disabled by default. In some cases, you might not want to use auto-registration; for
example, if you want to assign a specific directory number to the phone. For information about enabling
auto-registration, see the
“
Enabling Auto-Registration
