Requesting the Configuration File Description Related Topics 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. • Network Configuration Menu, page 4-7. • Resolving Startup Problems, page 9-2. 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 Unified CallManager. For more information, refer to Cisco Unified CallManager Security Guide The TFTP server has configuration files, which define parameters for connecting to Cisco Unified CallManager and other information for the phone. • Adding Phones to the Cisco Unified CallManag er Database, page 2-12 • Resolving Startup Problems, page 9-2.
