Field Name	Values	Description
Single Port Protocol (SPP)
Mode	Direct,	SPP voip systems can operate in
	Client, or	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 by
mission		absence of an acknowledgment)
(in ms)		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-
Re-trans-		transmit a lost packet (if no
mission		acknowledgment has been
		received). (Default value = 3)
