Gatekeepers play a major part in medium and large H.323 VoIP network solutions. Gatekeepers allow for dial-plan scalability and reduce the need to manage global dial plans locally. This course describes the functions of a gatekeeper and explains how to configure gatekeepers to interoperate with gateways. It also gives an overview of the Cisco Unified Border Element and describes how to implement a Cisco Unified Border Element within an enterprise network. A Cisco Unified Border Element has the ability to interconnect voice and VoIP networks, offering protocol interworking, address hiding, and security services.
