Gatekeeper
Gatekeeper is an administrational tool for H.232 multimedia networks. A single unit can control interactions for each zone, which comprises the terminals, MCU's and gateway within the frames of a particular domain. Gatekeeper is an optional element, but when it available, it becomes the central administrative entity.
In the past, when you call an office building or business, you would either be transferred to the department you want to talk to, or given their extension number. This extension is usually a 2-3 digit code that when dialed, transfers you automatically to the particular person or department you want to speak with. The reason why this code works is because it is programmed into a PBX system.
