Understanding the Phone Startup Process
7. Requesting the
Configuration File.
The TFTP server has configuration files, which
define parameters for connecting to
Cisco
Unified CallManager and other information
for the phone.
See the “Understanding
Phone Configuration
Files” section on
page 2-6.
See the “Resolving
Startup Problems”
section on page 9-2.
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.
See the “Resolving
Startup Problems”
section on page 9-2.
