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 Licensing section in the Cisco Unified Communications Manager
Features and Services Guide.
These sections describe the methods:
• Adding Phones with Auto-Registration, page 2-9
• Adding Phones with Auto-Registration and TAPS, page 2-10
• Adding Phones with Cisco Unified CM Administration, page 2-10
• Adding Phones with BAT, page 2-11
7. 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.
• Adding Phones to the Cisco Unified CM Database,
page 2-8.
• Resolving Startup Problems, page 9-1.
8. 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.
