Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Adding Phones to the Cisco Unified Communications Manager Database Table 2-4 provides an overview of these methods for adding phones to the Cisco Unified Communications Manager database. Table 2-4 Methods for Adding Phones to the Cisco Unified Communications Manager Database Method Auto-registration Auto-registration with TAPS Requires MAC Address? No No Using the Cisco Unified Yes Communications Manager Administration Using BAT Yes Notes Results in automatic assignment of directory numbers Requires auto-registration and the Bulk Administration Tool (BAT); updates information in the Cisco Unified IP Phone and in Cisco Unified Communications Manager 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 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 2-10. 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. 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 non-secure mode through the Cisco CTL client, auto-registration is automatically enabled.
