Configure H.323 Settings

If your network uses an H.323 gatekeeper, the system can automatically register its H.323 name and extension. Others can then call the system using its H.323 name or extension instead of its IP address.

Procedure

  1. In the system web interface, go to Call Configuration > H.323.
  2. Configure the following settings:
    Setting Description
    Enable IP H.323 Enables the system to display H.323 settings and configuration options.
    Registration Status Read-only setting shows if your system is registered with an H.323 gatekeeper.
    H.323 Name How gatekeepers and gateways identify your 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 device name unless you change it.

    Your organization’s dial plan might define the name you can use.

    H.323 Extension (E.164) You can place point-to-point calls using this extension if both systems are registered with a gatekeeper. Gatekeepers and gateways also use the extension to identify your system.

    Your organization’s dial plan might define the extensions you can use.

    Use Gatekeeper Specifies if you want to use a gatekeeper for H.323 services.
    • Off: Calls don’t use a gatekeeper.
    • Auto: System tries to automatically find an available gatekeeper.
    • Specify: Calls use the specified gatekeeper. You must select this setting to enable H.235 Annex D Authentication.

    If you don’t configure this setting to Off, a registration status displays.

    Require Authentication Enables support for H.235 Annex D Authentication.

    When you enable H.235 Annex D Authentication, the H.323 gatekeeper ensures that only trusted H.323 endpoints can access the gatekeeper.

    This setting is available when you set Use Gatekeeper to Specify.

    User Name Specifies a user name if the gatekeeper requires authentication for registration.
    Password Specifies a password if the gatekeeper requires authentication for registration.
    Current Gatekeeper IP Address

    Displays the IP address that the gatekeeper is using.

    If you select Off for the Use Gatekeeper field, the Current Gatekeeper IP Address field doesn’t display.

    Primary Gatekeeper IP Address The gatekeeper IPv4 address the system registers with. As part of the registration process, the gatekeeper might return alternate gatekeepers. If your system loses communication with the primary gatekeeper, your system registers with the alternate gatekeeper but continues to poll the primary gatekeeper. If the system re-establishes communication with the primary gatekeeper, it unregisters from the alternate gatekeeper.
    • If you set the Use Gatekeeper field to Off, the Primary Gatekeeper IP Address field doesn’t display.
    • If you use an automatically selected gatekeeper, this area displays the gatekeeper’s IP address.
    • If you specify a gatekeeper, enter the gatekeeper IP address or name (for example, 10.11.12.13 or gatekeeper.companyname.usa.com).
  3. Select Save.
