Services Definition
The Gatekeeper offers call services that enhance the normal call process by adding functions
such as automatic call forwarding and/or routing. To do this, an added address tag or
Prefix
must be assigned for each service. A service is automatically accessed when the Prefix is
added to the phone number dialed for a conference call.
Forward Prefix — You can define a prefix for the Forward service. When a terminal
wishes to notify the Gatekeeper to forward its calls, it requests the Forward service using
this prefix together with the new destination endpoint. Subsequently, when the Gatekeeper
receives a call for that terminal, it transfers the call to the new endpoint until the terminal
deactivates the
Forward service request.
Exit Zone — When you define a prefix for the Exit Zone service, you need to dial that
prefix to reach an endpoint in another zone. This is useful in restricting unauthorized users
from making calls to other zones. When this service is defined, the Gatekeeper only
completes calls to other zones if the
Exit Zone prefix is present in the dialed address string.
Zone Prefixes 1 and 2 — As the built–in Gatekeeper supports multiple zone environments,
this service lets you define one or two Prefixes for each zone of the Gatekeeper. Zone
Prefixes are similar to telephone area codes. If an endpoint in a zone dials a Zone Prefix
before its number, and the Gatekeeper cannot resolve it in its zone, the Gatekeeper attempts
to locate and route the call to the appropriate zone of the neighboring gatekeeper. On
receiving the call, the built–in Gatekeeper strips off the
Zone Prefix and applies a
destination location mechanism to route the call to its final destination.
