Cisco Unified IP Phone 7906G and 7911G for Cisco Unified Communications Manager 6.0
OL11954-01
Description
The TFTP server has configuration files, which
define parameters for connecting to
Cisco Unified Communications Manager and
other information for the phone.
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.
Auto-registration is disabled when
Note
security is enabled on
Cisco Unified Communications Manager.
In this case, the phone must be manually
added to the Cisco Unified
Communications Manager database.
