5. Accessing a TFTP
Server
In addition to assigning an IP address, the DHCP
server directs the Cisco 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.

6. Requesting the
CTL file
The TFTP server stores the certificate trust list
(CTL) file. This file contains a list of
Cisco 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 CallManager.
For more information,
refer to the
Cisco CallManager
Security Guide
7. Requesting the
Configuration File
The TFTP server has configuration files, which
define parameters for connecting to
Cisco CallManager and other information for the
phone.
