TFTP Server 1 Primary Trivial File Transfer Protocol
(TFTP) server used by the phone. If you
are not using DHCP in your network and
you want to change this server, you
must use the TFTP Server 1 option.
If you set the Alternate TFTP option to
yes, you must enter a non-zero value for
the TFTP Server 1 option.
If neither the primary TFTP server nor
the backup TFTP server is listed in the
CTL file on the phone, you must unlock
the CTL file before you can save
changes to the TFTP Server 1 option. In
this case, the phone will delete the CTL
file when you save changes to the TFTP
Server 1 option.
For information about the CTL file,
refer to Cisco Unified CallManager
Security Guide. For information about
unlocking the CTL file, see the
