securely registering with Cisco Unified CM.

Communications Manager Security Guide.

which can be automatically identified from the
DHCP server. If you want a phone to use a TFTP
server other than the one specified by the DHCP
server, you must manually assign the IP address of
the TFTP server by using the Network Setup menu
on the phone.
For more information, go to the
in the Cisco Unified Communications Manager
System Guide.
