	SIP Fields
Use Proxy	Y/N	Select if proxy server is used.
Transport	TCP or	VOIP administrator must choose between UDP and TCP transmission protocols.
Protocol	UDP	UDP is a high‐speed, low‐overhead connectionless protocol where data is
		transmitted without acknowledgment, guaranteed delivery, or guaranteed
		packet sequence integrity. TCP is slower connection‐oriented protocol with
		greater overhead, but having acknowledgment and guarantees delivery and
		packet sequence integrity.
SIP Port	5060 or other	The SIP Port Number is a UDP logical port number. The VOIP “listens” for SIP

	SPP Fields	The –SS series of MultiVOIPs do not support SPP
Use Registrar	Y/N	Select this checkbox to use registrar when VOIP system is operating in the
		“Registrar/Client” SPP mode. In this mode, one VOIP (the registrar, as set in
		Phonebook Configuration window) has a static IP address and all other VOIPs
		(clients) point to the registrar’s IP address as functionally their own. However, if
		your VOIP system overall is operating in “Registrar/Client” mode but you want
		to make an exception and use Direct mode for the destination pattern of this
		particular Add/Edit Phonebook entry, leave this checkbox unselected. Also do
		not select this if your overall VOIP system is operating in the Direct SPP mode –
		in this mode all VOIPs are peers with unique static IP addresses.
Port Number	numeric	When operating in “Registrar/Client” mode, this is the port by which the
		gateway receives all SPP data and control messages from the registrar gateway.
		(This ability to receive all data and messages via one port allows the VOIP to
		operate behind a firewall with only one port open.)
		When operating in “Direct” mode, this is the Port by which peer VOIPs receive
		data and messages.
Alternate	numeric	Phone number associated with alternate IP routing.
