[cisco-voip] tftp server 255.255.255.255

[Wes Sisk]

Are these phones with security enabled and CTL files? If so they will 
take option 150 or option 166 but will refuse to use the provided IP as 
it is not in the trust list.  The only way to recover them is to 
manually delete the CTL from the phone.  Navigate the UI on the LCD.
