Cisco CVOICE 8.0: Gatekeeper and Cisco Unified Border Element

Overview/Description
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.

Target Audience
The target audience for this course is established IT professionals with a solid, existing background in Cisco and networking technologies.

Expected Duration (hours)
3.0
