Understanding the Phone Startup Process
5. Accessing a TFTP
Server.
In addition to assigning an IP address, the DHCP
server directs the Cisco Unified IP Phone to a
TFTP Server. If the phone has a statically-defined
IP address, you must configure the TFTP server
locally on the phone; the phone then contacts the
TFTP server directly.
Note You can also assign an alternative TFTP
server to use instead of the one assigned by
DHCP.
See the “Network
Configuration Menu”
section on page 4-7.
See the “Resolving
Startup Problems”
section on page 9-2.
6. Requesting the
CTL file.
The TFTP server stores the certificate trust list
(CTL) file. This file contains a list of
Cisco Unified CallManagers 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 UnifiedCallManager.
Refer to the
CiscoUnified CallMan
ager Security Guide,
“Configuring the Cisco
CTL Client” chapter.
