Field Name	Values		Description
H.323 Version 4 Parameters
Q.931	Y/N		Signaling for multiple phone calls
Multiplexing			can be carried on a single port
(Mux)			rather than opening a separate
			signaling port for each call. This
			conserves bandwidth resources.
H.245	Values: Y/N
Tunneling (Tun)	Description: H.245 messages are encapsulated
	within the	Q.931 call-signaling channel. Among
	other things, the H.245 messages let the two
	endpoints tell each other what their technical
	capabilities are and determine who, during the
	call, will be the client and who the server.
	Tunneling is the process of transmitting these
	H.245 messages through the Q.931 channel. The
	same TCP/IP socket (or logical port) already being
	used for the Call Signaling Channel is then also
	used by the H.245 Control Channel. This
	encapsulation reduces the number of logical ports
	(sockets) needed and reduces call setup time.
