	Possible
Name	Values	Description
Boot Server (continued)	1=Custom	The phone will look for the option number specified by the Boot
		Server Option parameter (below), and the type specified by
		the Boot Server Option Type parameter (below) in the
		response received from the DHCP server.
		If the DHCP server sends nothing, the following scenarios are
		possible:
		• If a boot server value is stored in flash memory and the
		value is not “0.0.0.0”, then the value stored in flash is used.
		• Otherwise the phone sends out a DHCP INFORM query.
		- If a single alternate DHCP server responds, this is
		functionally equivalent to the scenario where the primary
		DHCP server responds with a valid boot server value.
		- If no alternate DHCP server responds, the INFORM query
		process will retry and eventually time out.
	2=Static	The phone will use the boot server configured through the
		Server Menu. For more information, refer to the next section,
		Server Menu.
	3=Custom+Option	The phone will first use the custom option if present or use
	66	Option 66 if the custom option is not present.
		If the DHCP server sends nothing, the following scenarios are
		possible:
		• If a boot server value is stored in flash memory and the
		value is not “0.0.0.0”, then the value stored in flash is used.
		• Otherwise the phone sends out a DHCP INFORM query.
		- If a single alternate DHCP server responds, this is
		functionally equivalent to the scenario where the primary
		DHCP server responds with a valid boot server value. The
		phone prefers the custom option value over the Option 66
		value, but if no custom option is given, the phone will use
		the Option 66 value.
		- If no alternate DHCP server responds, the INFORM query
		process will retry and eventually time out.
