Adding Phones to 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 

Licenses for Phones 

section in the 

Cisco Unified Communications 

Manager System Guide.

These sections describe the methods:

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.
