	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 phone sends out a DHCP INFORM query
		and the following scenarios are possible:
		• If no alternate DHCP server responds:
		- The INFORM query process will retry and eventually time
		out.
		- The boot server value stored in flash will be used.
		• 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.
	2=Static	The phone will use the boot server configured through the
		Server Menu. For more information, refer to the following
		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 phone sends out a DHCP INFORM
		query and the following scenarios are possible:
		• If no alternate DHCP server responds:
		- The INFORM query process will retry and eventually time
		out.
		- The boot server value stored in flash will be used.
		• A single alternate DHCP server responds.
		- 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. This is functionally equivalent
		to the scenario where the primary DHCP server responds
		with a valid boot server value.
