Configuring the Built–in Gatekeeper
4-32
The following are the configurable built–in Gatekeeper Settings :
GK On — This option allows you to enable or disable the built–in Gatekeeper. If you want
to work with an external gatekeeper, clear this check box. If you are working with the
built-in Gatekeeper, clearing this check box will disconnect all calls and unregister all
terminals. The
Accept Registration/Unregister All and the Accept Calls/Disconnect All
buttons allow you to close down the Gatekeeper function in an orderly manner .
Accept Registration/Unregister All — The Accept Registration option is normally
selected to allow endpoint registration to the Gatekeeper. If you want to close down the
Gatekeeper, you can clear this option to prevent new dynamic registrations from endpoints.
The
Unregister All button unregisters all endpoints that remain registered.
Accept Calls/Disconnect All — The Accept Calls option is normally selected to enable the
Gatekeeper to receive calls. If you want to close down the Gatekeeper, you can clear this
option to prevent the Gatekeeper from accepting new calls. The
Disconnect All button
disconnects all calls that remain connected.
Use Proxy for Unknown Zones — This option forces routing of incoming traffic from
zones of unknown gatekeepers through the Proxy. For more information on the Proxy, see
Supporting the H.323 Proxy.
Unregistration Timeout — This is the maximum length of time (in hours) that an endpoint
can remain inactive before its dynamic registration expires.
The following parameters allow you to control the network resources used by H.323 traffic:
Max. Number of Calls — The maximum number of simultaneous calls allowed in a zone.
The Gatekeeper can support up to 30 simultaneous calls. The default is 25. The Gatekeeper
will reject a new call if the number of ongoing calls reaches the value set for this parameter.
Max. Total Bandwidth — This parameter determines the total amount of bandwidth that
can be supported by the Gatekeeper at any given time.
Max. Bandwidth per Terminal — The maximum bandwidth use allowed per terminal.
This parameter applies to terminals only, and not to other endpoints such as gateways or
MCU-323s.
The following are miscellaneous Network Control settings:
GK Identifier — This is the name of the local Gatekeeper. Terminals identify the
Gatekeeper by this name during the discovery process. The Gatekeeper only responds to
discovery requests that contain either its identifier or no identifier. The default name is
RVGK.
Discovery Multicast — Use this to discover the gatekeeper using multicasting by entering
the IP address and port of the multicast channel (defaults are displayed).
Advanced Settings — This button displays the Advanced Settings screen that consists of
three parameters, listed below and shown in Figure 4-14 .
