Description
The TFTP server has configuration files, which
define parameters for connecting to
Cisco Unified CallManager and other information
for the phone.
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.
Auto-registration is disabled when
Note
security is enabled on
Cisco Unified CallManager. In this case,
the phone must be manually added to the
Cisco Unified CallManager database.
