7. Requesting 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

8. Contacting Cisco
Unified Communicatio
ns 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.
