6. Requesting the CTL
file.
The TFTP server stores the certificate trust list
(CTL) file. This file contains a list of Cisco
Unified
Communications Managers and TFTP
servers that the phone is authorized to connect to.
It also contains the certificates necessary for
establishing a secure connection between the
phone and Cisco Unified
Communications
Manager.
Refer to Cisco Unified
Communications
Manager Security
Guide, “Configuring the
Cisco CTL Client”
chapter.
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.
See the “Understanding
Phone Configuration
Files” section on
page 2-5.
See the “Resolving
Startup Problems”
section on page 9-2.
8. Contacting 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.
See the “Resolving
Startup Problems”
section on page 9-2.
