to specify the correct TFTP server.

phone may be configured with the wrong TFTP
server address. In this case, enter the correct
TFTP server address in the Network
Configuration menu on the phone.
If the TFTP server address is correct, there may
be a problem with the CTL file. In this case, run
the CTL client and update the CTL file, making
sure that the proper TFTP servers are included in
this file.
