Configuring Gatekeeper Use
Gatekeepers offer video users the ability to contact H.323 endpoints by entering an alias,
rather than having to remember each endpoint’s IP address. For example, you can dial “1234”
or “joesmith” and the gatekeeper routes the call correctly.
To do this, the gatekeeper must register all endpoints to maintain the mapping list of aliases
and endpoints to successfully route calls. It also registers gateways to ensure that a call can
be routed to a non-H.323 entity, since gateways form the bridge from H.323 to other
protocols, such as ISDN.
When registering with a gatekeeper like SCOPIA ECS Gatekeeper, the endpoint sends its IP and
aliases. Registration occurs before any calls are attempted and may occur periodically, or
once, such as during endpoint power-up.

Step 1
