Lab 15b: Configuring Voice over IP-Part II

Chapter 6. WAN Protocols and Technologies: Voice over X

Authoring contribution by Eric Sandberg

It's possible that the CCIE practical lab might include tasks involving the configuration of Cisco voice-capable routers for voice-over solutions (that is, voice over Frame Relay, Voice over IP and Voice over ATM). The purpose of this chapter is to give you enough information to successfully complete these configuration tasks . This chapter is not intended to be the "be all, end all" for information regarding telephony and voice-over solutions. Many good publications and Cisco classes are available to the general public that can fill that information void. I highly recommend Cisco Voice over Frame Relay, ATM, and IP and Voice over IP Fundamentals from Cisco Press, and any telephony or voice- related classes from a Cisco certified training partner.

This chapter covers Cisco voice-over technology solutions and tells where they fit into the network, highlights voice-capable Cisco products, discusses configuration and implementation, and enumerates the benefits of a voice-over solution, including reduced long distance costs, more calls with less bandwidth, more and better enhanced services, and more efficient use of the Internet Protocol (IP).

This chapter begins with a quick introduction to the basic elements of analog telephony. The overall objective is to teach engineers how to design, integrate, and configure voice over Frame Relay, ATM, and IP in the enterprise or managed network services using various Cisco 1750, 2600, 3600, and 3810 multiservice access devices.
