Adding Phones to the Cisco Unified Communications Manager Database
Adding Phones to the Cisco Unified Communications Manager
Database
Before installing the Cisco Unified IP phone, you must choose a method for adding phones to the
Cisco Unified Communications Manager database. These sections describe the methods:
• Adding Phones with Auto-Registration, page 2-10
• Adding Phones with Auto-Registration and TAPS, page 2-11
• Adding Phones with Cisco Unified Communications Manager Administration, page 2-12
• Adding Phones Using BAT Phone Template, page 2-12
10. Request the configuration file.
The TFTP server has configuration files, which define parameters for
connecting to Cisco Unified Communications Manager and other
information for the phone.
• Adding Phones to the Cisco
Unified Communications Manager
Database, page 2-9.
• Resolving Startup Problems,
page 12-1.
11. Contact 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 security profile of the phone is configured for secure signaling
(encrypted or authenticated), and the Cisco Unified CM is set to secure
mode, the phone makes a TLS connection. Otherwise, it makes a
nonsecure TCP connection.
If the phone was manually added to the database, Cisco
Unified Communications Manager identifies the phone. If the phone
was not manually added to the database and auto-registration is enabled
in Cisco Unified Communications Manager, the phone attempts to
auto-register itself in the Cisco Unified Communications Manager
database.
Note Autoregistration is disabled when you configure the CTL client.
In this case, the phone must be manually added to the Cisco
Unified CM database.
