Cisco Unified IP Phone Startup Process (continued)

Task

Purpose

Requesting the Configuration File

The TFTP server has configuration files, which define

parameters for connecting to Cisco Unified CM and

other information for the phone.

Contacting Cisco Unified CM

The configuration file defines how the Cisco

Unified IP Phone communicates with Cisco

Unified CM and provides a phone with its load ID.

After obtaining the file from the TFTP server, the

phone attempts to make a connection to the highest

priority Cisco Unified CM on the list.

If the phone was manually added to the database,

Cisco Unified CM identifies the phone. If the phone

was not manually added to the database and

auto-registration is enabled in Cisco Unified CM, the

phone attempts to auto-register itself in the Cisco

Unified CM database.

Adding Phones to the Cisco Unified CM Database

Before installing the Cisco Unified IP phone, you must choose a method for adding phones to the Cisco

Unified CM database. Be aware that each phone type requires a fixed number of device license units and

the number of unit licenses that are available on the server may impact phone registration. For more

information on licensing go to the

Manager System Guide.
