Cisco Unified IP Phone 7960G/7940G Administration Guide for Cisco Unified Communications Manager 7.0 (SIP)
OL-15499-01
Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
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 2-8
Adding Phones with Cisco Unified Communications Manager Administration, page 2-9
Adding Phones with BAT, page 2-9
Table 2-4 provides an overview of these methods for adding phones to the
Cisco Unified Communications Manager database.
7. 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 2-7
Resolving Startup Problems, page 7-1.
8. Contact Cisco Unified Communications Manager.
The configuration file defines how the Cisco Unified IP Phone
communicates with Cisco
Unified Communications Manager 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 Communications Manager on the
list. If security is implemented, the phone makes a TLS
connection. Otherwise, it makes a non-secure 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 Auto-registration is disabled when security is enabled on
Cisco
Unified Communications Manager. In this case, the
phone must be manually added to the Cisco
Unified
Communications Manager database.
