Field Name Values Description
Pre-Granted ARQ
PreGrant
ALL
Y/N Select to cause the Gatekeeper to send a pregrantedARQ permission in
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-
of-Service
Supplier
Y/N “Y” enables the sending of RAI messages. In a normal scenario, the
gatekeeper will hunt among all the available endpoints that have been
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
H.245 Addr
in Call Hunt
Y/N When selected, the gatekeeper will not convey in its outgoing setup
message the H.245 address received in an incoming setup message.
This prevents H.323 terminals from establishing a channel for a call
only to refuse the call later.
Service
Configurable
Properties
Y/N When “Y” is selected, the gatekeeper will perform a Priority Based Line
Hunting among those destinations registered using the same tech-
prefix.
Call Proceeding
This parameter group pertains to the gatekeeper’s handling of Q.931
“call-proceeding” messages.
Send
Immediately
Y/N Immediate return of call-proceeding message to originating endpoint.
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
Addr
Y/N When enabled, gatekeeper supplementary services will remove the
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
Overlapped
Sending
Y/N Delayed return of call-proceeding message to originating endpoint.
When selected (in routed mode), the gatekeeper will send a Q.931 call-
proceeding message to the originating endpoint after it receives a
return call-proceeding message back from the destination endpoint.
