Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified Communications Manager 8.0 (SCCP and SIP)
OL-20798-01
Description
The phone requests the ITL file after it requests the CTL
file. The ITL file contains the certificates of the entities
that the phone can trust. The certificates are used for
authenticating a secure connection with the servers or
authenticating a digital signature signed by the servers.
The ITL file is available to the phone only from Cisco
Unified Communications Manager 8.0 and later.
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 the security profile of the phone is
configured for secure signaling (encrypted or
authenticated) and the Cisco Unified Communications
Manager is set to secure mode, the phone makes a
TLS connection. Otherwise, it makes a nonsecure
TCP connection.
If the phone was manually added to the database, Cisco
Unified Communications Manager identifies the phone.
If the phone was not added manually 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 security is
Note
enabled on Cisco Unified Communications
Manager. In this case, the phone must be
manually added to the Cisco Unified
Communications Manager database.
