Adding Phones to the Cisco CallManager Database Chapter 2 Preparing to Install the Cisco IP Phone on Your Network Adding Phones to the Cisco CallManager Database Before installing any Cisco IP phones, you must make decisions about how you want the phones to be added to the Cisco CallManager database. Because Cisco CallManager handles call processing in the network, this is a critical step. You can add phones to the Cisco CallManager database automatically using auto-registration, manually using the Cisco CallManager Administration application, or in groups with the Bulk Administration Tool (BAT). Once you add a Cisco IP phone using the Cisco CallManager Administration application, the Phone Configuration Window in the application displays the device name, registration status, and the IP address of the Cisco CallManager to which the device is registered. This section covers the following topics: • Using Auto-Registration, page 2-12 • Adding Phones Manually, page 2-14 • Using the Bulk Administration Tool, page 2-17 Tip To get help using the Cisco CallManager application, access context-sensitive help by choosing Help > For this page from the main menu bar. For complete instructions and conceptual information, refer to Cisco CallManager Administration Guide and Cisco CallManager System Guide. Using Auto-Registration Use auto-registration if you want Cisco CallManager to assign directory numbers automatically to new phones as they connect to the IP telephony network. Once a phone has auto-registered, you can move it to a new location and assign it to a different device pool without affecting its directory number. With auto-registration enabled, Cisco CallManager begins the automatic startup process to obtain a directory number as soon as you connect the Cisco IP Phone to the network. During auto-registration, Cisco CallManager automatically assigns the next available sequential directory number to the phone. 2-12 Cisco IP Phone Administration Guide for Cisco CallManager 3.3, Cisco IP Phones 7902G/7905G/7912G OL-6313-01
