	Field Name	Values	Description
	Single Port Protocol (SPP)
	Mode	Direct,	SPP voip systems can operate
		Client, or	in two modes:
		Registrar	in the direct mode, where all
			voip gateways have static IP
			addresses assigned to them; or
			in the registrar/client mode,
			where one voip gateway
			serves as registrar and all
			other gateways, being its
			clients, point to that registrar.
			The registrar assigns IP
			addresses dynamically.
	General Options
	Port		The UDP port on which data
			transmission will occur. Each
			client voip has its own port. If
			two client voips are both
			behind the same firewall, then
			they must have different ports
			assigned to them.
			If there are two clients and
			each is behind a different
			firewall, then the clients could
			have different port numbers or
			the same port number.
			(Default port number = 10000.)
	Re-trans-		If packets are lost (as indicated
	mission		by absence of an
	(in ms)		acknowledgment) then the
			endpoint will retransmit the
			lost packets after this
			designated time duration has
			elapsed. (Default value = 2000
			milliseconds.)
	Max		Number of times the voip will
	Re-trans-		re-transmit a lost packet (if no
	mission		acknowledgment has been
			received). (Default value = 3)
