Gatekeeper

Use the Gatekeeper screen to establish connections with your network’s H.323 gatekeeper.

Registering with a gatekeeper lets you make calls using gateways and some Multi-point Conferencing Units (MCUs).

The Gatekeeper screen provides the following options:

Off Makes no gatekeeper connection. Use this option when no gatekeeper is present on the network.

Specify Lets you manually enter the Gatekeeper address in the Gatekeeper IP Address field. Use this option when you have more than one gatekeeper on your network.

Auto ViaVideo searches for a gatekeeper on your network, and connects to the first gatekeeper it finds. Use this option if you have only one gatekeeper on your network.

If you select Auto and ViaVideo is not able to find a gatekeeper, be sure that you have a gatekeeper, and that it is correctly configured.
