Course Information

Course Description

This five-day course covers the essential topics of converged voice and data networks and also the challenges faced by the various network technologies. The course also provides network administrators and network engineers with the knowledge and skills required to integrate gateways and gatekeepers into an enterprise VoIP network.

This course is one of several courses in the Cisco CCVP track that addresses design, planning, and deployment practices and provides comprehensive hands-on experience in configuration and deployment of VoIP networks.

Course Objectives


​At the end of this course, you'll be able to:
  1. Describe VoIP, voice gateways, special requirements for VoIP calls, codecs and codec complexity, and how DSPs are used as media resources on a voice gateway
  2. Configure gateway interconnections to support VoIP and PSTN calls and to integrate with a PSTN and PBX
  3. Describe the basic signaling protocols that are used on voice gateways and configure a gateway to support calls using the various signaling protocols
  4. Define a dial plan, describe the purpose of each dial plan component, and implement a dial plan on a voice gateway
  5. Implement gatekeepers and directory gatekeepers, and identify redundancy options for gatekeepers
  6. Implement a Cisco UBE gateway to connect to an Internet telephony service provider

Course Audience

This course is intended for students who have general working knowledge of Local and Wide Area Networks and basic configuration of voice and data networks. Network engineers, architects, and support staff that require a fundamental understanding of packet telephony technologies that are common for both enterprise and service provider applications will also benefit for this course.
