Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
Adding Phones to the Cisco Unified Communications Manager Database
Table 2-5 provides an overview of these methods for adding phones to the
Cisco Unified Communications Manager database.
Adding Phones with Auto-Registration
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.
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 2-12.
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 or if you plan to implement
authentication or encryption, as described in Cisco Unified Communications Manager Security Guide.
For information about enabling auto-registration, refer to “Enabling Auto-Registration” in the Cisco
Unified Communications Manager Administration Guide.
