Option	Description
Gateway dial-out	Select the communication protocols to be used for
Protocol	dialing out to the destination participant(s).
	The system starts by connecting the participant using
	the first selected protocol. If the call is not answered or
	it cannot be completed using one communication
	protocol, the system will try to connect the endpoint
	using the next communication protocol in the following
	order: H.323, SIP and ISDN. PSTN numbers are
	identified separately and are dialed right away without
	trying other connections.
	By default, all protocols (H.323, SIP, ISDN and PSTN)
	are selected. Clear the protocol that should not be
	used for connecting the destination endpoint.
Enable ISDN/	Select this check box to allocate dial-in numbers for
PSTN Dial-in	ISDN/PSTN connections.
	To define the first dial-in number using the default
	ISDN/PSTN Network Service, leave the default
	selection. When the Entry Queue is saved on the
	MCU, the dial-in number will be automatically
	assigned to the Entry Queue. This number is taken
	from the dial-in numbers range in the default ISDN/
	PSTN Network Service.
	Note: Even if ISDN/PSTN is disabled for dial-in, if an
	ISDN/PSTN Network Service is defined in the system,
	and ISDN and/or PSTN are enabled for dialed out, the
	system will used the default ISDN Network Service for
	dialing out to the target number.
ISDN/PSTN	The default Network Service is automatically selected.
Network Service	To select a different ISDN/PSTN Network Service in
	the service list, select the name of the Network
	Service.
Dial-in Number	Leave this field blank to let the system automatically
(1)	assign a number from the selected ISDN/PSTN
	Network Service. To manually define a dial-in number,
	enter a required number from the dial-in number
	range defined for the selected Network Service.
