Cisco CallManager is the call control component in the network that handles and
routes calls for the Cisco Wireless IP Phone 7920. Cisco CallManager manages
the components of the IP telephony system—the phones, access gateways, and the
resources—for such features as call conferencing and route planning. You must
use Cisco CallManager Release 3.3(3) SR1 or later for wireless voice
deployments.
Before Cisco CallManager can recognize a phone, it must register with
Cisco CallManager and be configured in the database. For information about
setting up phones in Cisco CallManager, see the
Cisco CallManager" section on page
You can find more information about configuring Cisco CallManager to work
with the IP phones and IP devices in the Cisco CallManager Administration
Guide and Cisco CallManager System Guide.

Configuration files for a phone define parameters for connecting to
Cisco CallManager and are stored on the TFTP server. In general, any time you
make a change in Cisco CallManager Administration that requires resetting the
phone, the phone configuration file changes automatically.
Configuration files also contain information about the correct image load for the
phone. If this image load differs from the one currently loaded on a phone, the
phone contacts the TFTP server to request the new image file.
