Adding Phones to the Cisco Unified CallManager Database
Adding Phones to the Cisco Unified CallManager
Database
Before installing the Cisco Unified IP phone, you must choose a method for
adding phones to the Cisco Unified CallManager database. These sections
describe the methods:
• Adding Phones with Auto-Registration, page 2-12
• Adding Phones with Auto-Registration and TAPS, page 2-13
• Adding Phones with Cisco Unified CallManager Administration, page 2-14
• Adding Phones with BAT, page 2-15
8. Contacting Cisco
Unified CallManager The configuration file defines how the Cisco
Unified IP Phone communicates with Cisco
Unified CallManager 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 CallManager 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 CallManager identifies the phone.
If the phone was not manually added to the
database and auto-registration is enabled in Cisco
Unified CallManager, the phone attempts to
auto-register itself in the Cisco
Unified CallManager database.
Note Auto-registration is disabled when
security is enabled on Cisco
Unified CallManager. In this case, the
phone must be manually added to the
Cisco Unified CallManager database.
