Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE for Cisco Unified Communications Manager 6.1
OL-14620-01
Description
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
Note
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.
