Chapter 3 - Before You Deploy

Gatekeeper Identifier
You will need to specify the gatekeeper identifier for each
gatekeeper being deployed. You must also define the maximum
number of endpoints that may be registered to each gatekeeper and
the maximum number of calls that each gatekeeper may handle at
one time.
Default Gatekeeper
An endpoint may register to a gatekeeper automatically or
manually. If endpoint registration is automatic, the registration
policy must specify a default gatekeeper — more than one
gatekeeper may exist on the network.
The registration policy defines the endpoints that may register to the
gatekeeper. It may allow any endpoint to register, or it may restrict
registration to specific endpoints or endpoints on specific networks.
Call Routing Mode
The default call mode may be direct or routed. In direct call mode,
the gatekeeper allows endpoints to send messages directly to each
other — the calls do not need to be routed through the gatekeeper.
If direct call mode is used, gatekeeper functionality (such as
simplified dialing, Conference on Demand, and alternate routing) is
not available, because the call bypasses the gatekeeper.
Developing the Dial Plan
The final element of the predeployment preparations is the dial
plan.
The dial plan defines how you set numeric aliases and service
prefixes. Numeric aliases look like telephone numbers. They allow
people to dial a short string of numbers like a telephone extension
or local telephone number instead of entering a full IP address.
