Configure the System to Use a Gatekeeper
A gatekeeper manages functions such as bandwidth control and admission control. The gatekeeper also
handles address translation, which allows users to make calls using static aliases instead of IP addresses
that can change each day.
To configure the system to use a gatekeeper:
1
In the web interface, go to Admin Settings > Network > IP Network > H.323 Settings.
2
Configure the following settings.
Setting
Description
Enable IP H.323
Allows the H.323 settings to be displayed and configured.
H.323 Name
Specifies the name that gatekeepers and gateways use to identify this system.
You can make point-to-point calls using H.323 names if both systems are
registered to a gatekeeper.
The H.323 Name is the same as the System Name, unless you change it. Your
organization’s dial plan might define the names you can use.
H.323 Extension (E.164)
Lets users place point-to-point calls using the extension if both systems are
registered with a gatekeeper, and specifies the extension that gatekeepers and
gateways use to identify this system.
Your organization’s dial plan might define the extensions you can use.
Setting
Description
Use Gatekeeper
Select this setting to use a gatekeeper. Gateways and gatekeepers are required for
calls between IP and ISDN.
•
Off—Calls do not use a gatekeeper.
•
Auto—System attempts to automatically find an available gatekeeper.
•
Specify—Calls use the specified gatekeeper. This option must be selected to
enable H.235 Annex D Authentication.
When you select a setting other than Off, the Registration Status is displayed
below the Enable IP H.323 setting.
Require Authentication
Enables support for H.235 Annex D Authentication.
When H.235 Annex D Authentication is enabled, the H.323 gatekeeper ensures
that only trusted H.323 endpoints are allowed to access the gatekeeper.
This setting is available when Use Gatekeeper is set to Specify.
User Name
When authentication is required, specifies the user name for authentication with
H.235 Annex D.
Enter Password
When authentication is required, specifies the password for authentication with
H.235 Annex D.
