Chapter
Adding Phones to the Cisco Unified CM Database
Table 2-4 provides an overview of these methods for adding phones to the Cisco Unified CM 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 CM database when you physically
connect the phone to your IP telephony network. During auto-registration, Cisco Unified CM
assigns the next available sequential directory number to the phone.
Quickly enter phones into the Cisco Unified CM database and modify any settings, such as the
directory numbers, from Cisco Unified CM.
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 “A dding Phones with
BAT” section on page 2-11.
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, go to the “Enabling Auto-Registration” section in the Cisco Unified Communications
Manager Administration Guide.

Method
Requires MAC
Address? Notes
Auto-registration No Results in automatic assignment of directory
numbers
Not available when security or encryption is
enabled
Note Auto-registration is disabled when
security is enabled on Cisco Unified CM.
In this case, the phone must be manually
added to the Cisco Unified CM database.
Auto-registration with
TAPS No Requires auto-registration and the Bulk
Administration Tool (BAT); updates information
in the Cisco Unified IP Phone and in Cisco
Unified CM Administration
Using the Cisco Unified
CM Administration Yes Requires phones to be added individually
Using BAT Yes Allows for simultaneous registration of multiple
phones
