gatekeeper
A gatekeeper is an H.323 service component that supports the deployment of an H.323 service. A gatekeeper provides management functions to terminals. These include address translation, call set-up, service access control, and call logging. These services are accessed by a terminal ‘registering’ with a particular gatekeeper. All terminals registered with a particular gatekeeper are in its ‘zone’. Gatekeepers are usually deployed on the network to reflect organisational or geographical network topology.
