IP Communications: Voice Over IP (VoIP) (5 day)

Course Overview

CVOICE 4.2 is the first course in the Cisco Voice Professional Curriculum, a curriculum track that starts at the basics of packetized voice and builds up to a true voice professional level.

CVOICE lays the foundation for gaining hand-on skills and significant understanding of packet telephony by presenting the technologies that are common for both Enterprise and Service Provider students. The course also teaches students how to use the available Cisco tools to find the information needed to accomplish their everyday tasks. Since no two networks are alike, this approach enables a student to apply the knowledge gained in this course to their specific needs.

Skills Gained

• Identify the components, processes, and features of traditional telephony networks that provide end-to-end call functionality
• Describe two methods of call control used on voice and data networks and provide one example of a protocol for each
• List at least five components or capabilities that are required to provide integrated voice and data services in campus LAN, enterprise, and service provider environments
• Select the appropriate analog voice connection to a Cisco device given the types of analog connections and their susceptibility to line quality problems
• Choose a voice compression scheme that best suits your needs given the fundamentals of digital voice encoding
• Describe the appropriate signaling method to deploy in a telephony system given the type of signaling: between PBXs; between PBXs and central offices; or specialized, such as ISDN
• Implement an effective method of transporting fax and modem traffic over a Voice over IP network given the standard implementations of fax and the methods used to transport modem traffic

Prerequisites

To fully comprehend the concepts and technologies taught in this course, a working knowledge of LANs, WANs, and IP switching and routing is essential. Basic internetworking skills taught in the Interconnecting Cisco Network Devices training course, or equivalent knowledge, is considered the minimum knowledge needed for this course.

Although this is a packetized voice course, knowledge of the how and whys of the traditional PSTN operations and technologies is required.
