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. Table 2-4 Methods for Adding Phones to the Cisco Unified CM Database Method Auto-registration Requires MAC Address? No Auto-registration with No TAPS Using the Cisco Unified Yes CM Administration Using BAT Yes Notes • 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. Requires auto-registration and the Bulk Administration Tool (BAT); updates information in the Cisco Unified IP Phone and in Cisco Unified CM Administration Requires phones to be added individually Allows for simultaneous registration of multiple phones 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 "Adding 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.
