Field Name	Values	Description
Operating	surviv.,	In “Survivability” mode, the MVP-SS
Mode	stnd-alone	unit can function as a SIP server for
		other gateways in its network in case
		that network loses contact with the
		network’s main SIP server (typically a
		PBX). When in “Survivability” mode,
		the MVP-SS unit is, essentially, a
		backup SIP server.
		In “Stand-Alone” mode, the MVP-SS
		functions as a primary SIP server for
		other gateways. In stand-alone mode,
		the MVP-SS operate to technical
		advantage with ‘smart’ SIP phones.
		Such smart SIP phones can choose the
		SIP server under which they operate
		and, consequently, can be controlled
		by either the SIP-based PBX or by the
		MVP-SS.
Survivability	Register,	One of two status-check packets is
Status Check	Options	sent to the main SIP Proxy servers to
		which the MVP-SS serves as a backup.
		Regardless of the packet type used,
		this packet determines whether the
		MVP-SS needs to take over SIP server
		functions or stay in its normal backup
		mode. “Options” and “Register” are
		two distinct SIP request “methods.”
		The Options method solicits
		information but does not set up a
		connection. The Register method
		conveys information about a user’s
		location to the SIP server. The
		“Register” method may entail more
		data overhead than the “Options”
		method. If both of these methods are
		supported by your SIP server, it is OK
		to use either one. If only one is
		supported, use the supported method.
