Network Control Parameters
The Network Control screen contains the following read-only parameters:
Ongoing Calls – displays the number of currently ongoing calls in the zone.
Online Endpoints – displays the number of endpoints currently registered with the
Gatekeeper.
Current Bandwidth Usage – displays the bandwidth being used by H.323 calls in the zone.
Following are the parameters you can edit:
Registration Policy Parameters
Everyone Can Register – Determines whether endpoints not defined in the Zone Definition
Table can register with the Gatekeeper. When selected, all endpoints can register with the
Gatekeeper. Otherwise, you will create a strict zone where only predefined endpoints can
register with the Gatekeeper. See "Zone Definition," page 6-7 for details on defining zones.
Alias Assignment – Set this parameter for the Gatekeeper to assign predefined aliases not
declared in the registration process to the endpoint. Otherwise, you can only place calls to
the aliases declared in the registration request and not to the predefined aliases. You can,
however, place calls to aliases of a predefined endpoint that is defined as Online Always.
See "Adding a New Endpoint" page 6-12 for details on predefining endpoints.
Call Indirect – Set this parameter to oblige all calls to be routed via the Gatekeeper.
Indirect call mode provides call control functions as well as routing information. Calls
requesting services are routed through the Gatekeeper regardless of this parameter.
When disabled, calls are routed directly. The Gatekeeper only provides routing information
to endpoints and does not provide call control functions thereby using fewer Gatekeeper
resources.
Dynamic IP Environment – You can set the Gatekeeper to work in a dynamic IP
environment. In a dynamic IP environment, terminals get different IP addresses at each start
up. Because the terminal IP is not fixed, the Gatekeeper cannot identify the terminal by its
IP address. Instead, the Gatekeeper uses the terminal aliases for identification.
If your network is not governed by DHCP, you can use the Gateway dynamic IP
environment support to allow user migration between workstations without the need to
forward calls. Users can move between workstations and may be on different workstations
each time they start up. When this parameter is set, the Gateway allows H.323 endpoints
that have registered with an IP address to reregister with a different IP address but with the
same terminal IDs and phone numbers. Calls to an endpoint whose IP has been changed are
routed to the last IP the endpoint registered with, and no forwarding is needed. See
"Predefining Endpoints in a Dynamic IP Environment," page 6-15 for details on predefining
endpoints when the Dynamic IP Environment parameter is selected.
