Downloading Load ID. The wireless IP phone checks to verify that the proper firmware is installed or if
new firmware is available to download.
Cisco Unified Communications Manager informs devices using .cnf or .cnf.xml format configuration files
of their load ID. Devices using .xml format configuration files receive the load ID in the configuration
file.
For more information, see Phone Configuration Files and Profile Files, on page 37.

Downloading configuration file. The TFTP server has configuration files and profile files. A configuration
file includes parameters for connecting to Cisco Unified Communications Manager and information about
which image load a phone should be running. A profile file contains various parameters and values for
phone and network settings.

Connecting to Cisco Unified Communications Manager.
The configuration file defines how the Cisco Unified IP Phone communicates with Cisco
Unified Communications Manager. After obtaining the file from the TFTP server, the phone attempts to
make a TCP connection to the highest priority Cisco Unified Communications Manager on the list.

Startup and Connectivity Problems, on page 209
8
Registering to Cisco Unified Communications Manager.
If the phone was manually added to the database, Cisco Unified Communications Manager identifies and
registers the phone. If the phone was not manually added to the database and autoregistration is enabled
in Cisco Unified Communications Manager, the phone attempts to autoregister itself in the Cisco
Unified Communications Manager database.
