		Network Parameter Definitions (cont’d)
Field Name	Values	Description
Pre-Granted	ARQ
PreGrant	Y/N	Select to cause the Gatekeeper to send a pregrantedARQ permission in
ALL		the RCF message for each endpoint that wishes to register. The
		pregranted ARQ permission is given to both makeCall and answerCall
		with routed mode. When an endpoint receives the permission, it may
		start the call with a Setup message or directly answer the call with a
		Connect message.
Line Hunting
Information
Call to Out-	Y/N	“Y” enables the sending of RAI messages. In a normal scenario, the
of-Service		gatekeeper will hunt among all the available endpoints that have been
Supplier		registered using the same tech-prefix. Each endpoint can inform the
		gatekeeper about its resource availability using an RAI (Resource
		Available Indication) message. Upon receiving an RAI message from
		an endpoint, the gatekeeper would consider that endpoint as an Out-of-
		Service Supplier. The ‘Almost Out of Resources’ configuration would
		allow the gatekeeper to hunt such Out-of-Service Supplier endpoints
		for routing the calls.
Remove	Y/N	When selected, the gatekeeper will not convey in its outgoing setup
H.245 Addr		message the H.245 address received in an incoming setup message.
in Call Hunt		This prevents H.323 terminals from establishing a channel for a call
		only to refuse the call later.
Service	Y/N	When “Y” is selected, the gatekeeper will perform a Priority Based Line
Configurable		Hunting among those destinations registered using the same tech-
Properties		prefix.
Call Proceeding		This parameter group pertains to the gatekeeper’s handling of Q.931
		“call-proceeding” messages.
Send	Y/N	Immediate return of call-proceeding message to originating endpoint.
Immediately		When selected, the gatekeeper will send the Q.931 call –proceeding
		message to the originating endpoint immediately after receiving that
		endpoint’s call setup request.
With H.245	Y/N	When enabled, gatekeeper supplementary services will remove the
Addr		H.245 address from the outgoing setup in order to prevent early H.245
		establishment to the call’s destination. This destination can be changed
		during Forward on Busy or during Forward on No Response (CFNR).
After	Y/N	Delayed return of call-proceeding message to originating endpoint.
Overlapped		When selected (in routed mode), the gatekeeper will send a Q.931 call-
Sending		proceeding message to the originating endpoint after it receives a
		return call-proceeding message back from the destination endpoint.
