Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
Adding Phones to Cisco Unified CM
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 that you use auto-registration to add fewer than 100 phones to your network. To add
more than 100 phones to your network, use the Bulk Administration Tool (BAT). See Adding Phones
with BAT, page 2-10.
Auto-registration is disabled by default. In some cases, you may 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 use secure
connection with Cisco Unified CM, as described in the Cisco Unified Communications Manager
Security Guide. For information about enabling auto-registration, see the Cisco Unified Communications
Manager Administration Guide, Cisco Unified Communications Manager Configuration.
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 nonsecure mode through the Cisco CTL
client, auto-registration is not enabled automatically.

Method
Requires
MAC
Address? Notes
Auto-registration No Results in automatic assignment of directory numbers.
Not available when security or encryption is enabled.
Auto-registration
with TAPS
No Requires auto-registration and the Bulk Administration Tool (BAT);
updates the Cisco Unified CM database with the MAC address and
DNs for the device when user calls TAPS from the phone.
Using Cisco Unified
CM Administration
Yes Requires phones to be added individually.
Using BAT Yes Can add groups of same model of phone.
Can schedule when phones are added to the Cisco Unified
CM database.
