Introduction

Introduction

With the rapid adoption of Voice over IP (VoIP), many telephony and data network technicians, engineers, and designers are now working to become proficient in VoIP. Professional certifications, such as the Cisco Certified Voice Professional (CCVP) certification, offer validation of an employee's or a consultant's competency in specific technical areas.

This book mirrors the level of detail found in the Cisco CVOICE Version 6.0 course, which many CCVP candidates select as their first course in the CCVP track. Version 6.0 represents a significant update over Version 5.0 of the CVOICE course, because Version 6.0 integrates much of the content previously found in the more advanced Implementing Cisco Voice Gateways and Gatekeepers (GWGK) course.

A fundamental understanding of traditional telephony, however, would certainly benefit a CVOICE student or a reader of this book. If you think you lack a fundamental understanding of traditional telephony, a recommended companion for this book is the Cisco Press Voice over IP First-Step book (ISBN: 978-1-58720-156-1), which is also written by this book's author. Voice over IP First-Step is written in a conversational tone and teaches concepts surrounding traditional telephony and how those concepts translate into a VoIP environment.

Additional Study Resources

This book contains a CD with approximately 90 minutes of video, where you will see the author demonstrate a variety of basic VoIP configurations. The videos were originally developed for NetMaster Class (http://www.netmasterclass.com), a company specializing in CCIE Lab training. These video-on-demand titles are as follows:

Analog Voice Port Configuration
Digital Voice Port Configuration
Dial Peer Configuration
H.323 Configuration
MGCP Configuration
SIP Configuration

As an additional reference for readers pursuing the CCVP certification, the author has created a website with recommended study resources (some free and some recommended for purchase) for all courses in the CCVP track. These recommendations can be found at the following URL: http://www.voipcertprep.com.

Goals and Methods

The primary objective of this book is to help the reader pass the 642-436 CVOICE exam, which is a required exam for the CCVP certification and for the Cisco Rich Media Communications Specialist specialization.

One key methodology used in this book is to help you discover the exam topics that you need to review in more depth, to help you fully understand and remember those details, and to help you prove to yourself that you have retained your knowledge of those topics. This book does not try to help you pass by memorization, but helps you truly learn and understand the topics by using the following methods:

Helping you discover which test topics you have not mastered
Providing explanations and information to fill in your knowledge gaps, including detailed illustrations and topologies as well as sample configurations
Providing exam practice questions to confirm your understanding of core concepts

Who Should Read This Book?

This book is primarily targeted toward candidates of the CVOICE exam. However, because CVOICE is one of the Cisco foundational VoIP courses, this book also serves as a VoIP primer to noncertification readers.

Many Cisco resellers actively encourage their employees to attain Cisco certifications and seek new employees already possessing Cisco certifications, for deeper discounts when purchasing Cisco products. Additionally, having attained a certification communicates to your employer or customer that you are serious about your craft and have not simply "hung out a shingle" declaring yourself knowledgeable about VoIP. Rather, you have proven your competency through a rigorous series of exams.

How This Book Is Organized

Although the chapters in this book could be read sequentially, the organization allows you to focus your reading on specific topics of interest. For example, if you already possess a strong VoIP background, you could skim the first two chapters (which cover foundational VoIP topics, including an introduction to VoIP and elements of a VoIP network) and focus on the remaining seven chapters, which address more advanced VoIP concepts. Specifically, the chapters in this book cover the following topics:

Chapter 1, "Introducing Voice over IP Networks": This chapter describes VoIP, components of a VoIP network, the protocols used, and service considerations of integrating VoIP into an existing data network. Also, this chapter considers various types of voice gateways and how to use gateways in different IP telephony environments.

Chapter 2, "Considering VoIP Design Elements": This chapter describes the challenges of integrating a voice and data network and explains solutions for avoiding problems when designing a VoIP network for optimal voice quality. Also, you learn the characteristics of voice codecs and digital signal processors and how to perform bandwidth calculations for VoIP calls.

Chapter 3, "Routing Calls over Analog Voice Ports": This chapter describes the various call types in a VoIP network. You then learn how to configure analog voice interfaces as new devices are introduced into the voice path. Finally, you discover how to configure dial peers, in order to add call routing intelligence to a router.

Chapter 4, "Performing Call Signaling over Digital Voice Ports": This chapter describes various digital interfaces and how to configure them. Also, you are introduced to Q Signaling (QSIG) and learn how to enable QSIG support.

Chapter 5, "Examining VoIP Gateways and Gateway Control Protocols": This chapter details the H.323, MGCP, and SIP protocol stacks, and you learn how to implement each of these protocols on Cisco IOS gateways.

Chapter 6, "Identifying Dial Plan Characteristics": This chapter describes the components and requirements of a dial plan and discusses how to implement a numbering plan using Cisco IOS gateways.

Chapter 7, "Configuring Advanced Dial Plans": This chapter shows you how to configure various digit manipulation strategies using Cisco IOS gateways. Additionally, you learn how to influence path selection. This chapter then concludes with a discussion of the Class of Restriction (COR) feature, and you learn how to implement COR on Cisco IOS gateways to specify calling privileges.

Chapter 8, "Configuring H.323 Gatekeepers": This chapter describes the function of a Cisco IOS gatekeeper. Also, you learn how to configure a gatekeeper for functions such as registration, address resolution, call routing, and call admission control (CAC).

Chapter 9, "Establishing a Connection with an Internet Telephony Service Provider": This chapter describes Cisco Unified Border Element (Cisco UBE) functions and features. You learn how a Cisco UBE is used in current enterprise environments and how to implement a Cisco UBE router to provide protocol interworking.
