Description
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.
You can also assign an alternative TFTP
Note
server to use instead of the one assigned
by DHCP.
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.
The TFTP server has configuration files, which
define parameters for connecting to
Cisco CallManager and other information for the
phone.
