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.
