What is voice gatekeeper?
The Role of Voice Gatekeepers: Gatekeepers help VoIP networks scale to large sizes. Companies that have geographically dispersed voice networks, or networks that have become so large that they are unwieldy, might opt to segment their network. In a CallManager network, you can create multiple clusters.

Depending on where the voice traffic originates from a VoIP gateway will convert the voice traffic into the proper form for receipt by the destination network (IP or PSTN).
What is the Cisco gatekeeper configuration for Cisco VoIP?
The Cisco gatekeeper configurations for this topology differ from a regular VoIP implementation in these ways: Each gateway for the gateway setup registers with the local gatekeeper with use of the h323–gateway voip interface commands. In this case, the gateways are AS5300s, and the gatekeeper is the 3640.
Do I need a gatekeeper on a Cisco 3640?
At each site, there is a gatekeeper configuration that runs on a Cisco 3640. In the topology that this section shows, a gatekeeper is not really necessary in order to place simple VoIP calls between the two gateways. But the diagram includes a gatekeeper in order to show how the complete configuration looks.
How does the gatekeeper process work?
Then, the gatekeeper replies to the call request with the IP address of the registered gateway that has the technology prefix ( tech–prefix) that matches the called number. These steps explain how the gatekeeper process works.
How do I register each gateway to the local gatekeeper?
Each gateway for the gateway setup registers with the local gatekeeper with use of the h323–gateway voip interface commands. In this case, the gateways are AS5300s, and the gatekeeper is the 3640.
