Deploying Cisco Voice over IP Solutions

If you've got a wide area network (WAN) already, putting interoffice voice traffic on it is an obvious application for it. Voice signals take up so little bandwidth, and the cost savings can be so significant, that Voice over IP (VoIP) deserves serious consideration. However, you can easily throw away years of cost savings by bringing in consultants to implement your VoIP solution. Deploying Cisco Voice over IP Solutions is meant to help organizational information technology people (as well as engineers at service providers and, for that matter, the expensive consultants) learn how to design, implement, and fine-tune VoIP systems that center on equipment and software from Cisco Systems. This book is all about Quality of Service (QoS), capacity management (gatekeeping), and network design. Cisco's implementations of fax services (under T.37 and T.38) and unified messaging (under uOne) are covered as well, but the authors leave most call-control matters to this book's companion volume, Cisco CallManager Fundamentals: A Cisco AVVID Solution.

The authors' approach, in large part, takes the form of a series of engineering problems, in which answers to design questions are given with lots of supporting math, equipment specifications, and references. In a discussion of setting up a transcontinental VoIP network, for example, the authors show how to configure Internetwork Operating System (IOS) 12.x to act as a gatekeeper and interact with CallManagers at both sites. There's IOS syntax, of course, but also a discussion of how Hot Standby Routing Protocol (HSRP) affects gatekeeping duties, and a complete table of options. A well-thought-out system for providing prepaid calling-card services on a VoIP network--meaning there's a database and authentication built into the call flow--is a great conclusion. --David Wall

Topics covered: Design- and implementation-time considerations for building a Voice over IP (VoIP) network on Cisco Systems hardware and software. Traffic analysis, echo, Quality of Service (QoS), dial plans, and extended services like fax and messaging get the attention of the all-Cisco authorial team.


Book Description

Learn real-world voice-over-IP deployment solutions and strategies from the Cisco experts

Deploying Cisco Voice over IP Solutions covers:
Definitive guidelines on real-world VoIP deployments, the fundamentals of the latest VoIP solutions, and a look into the future of VoIP servicesDifferent techniques for engineering and properly sizing traffic-sensitive voice networksBasic concepts applicable to echo analysis, echo cancellation, and locating and eliminating echoesVarious QoS features applicable to voiceDetailed information on call admission control (CAC)Dial plan configuration recommendations on Cisco H.323 gateways and gatekeepers used to support large dial plansBasic tasks of designing a long-distance VoIP networkThe two classes of hosted voice networks: Managed Multiservice (MMS) networks and packet voice VPNsFax services store and forward as well as real-time relay fax servicesSample configurations and step-by-step examples to help you learn how to build a VoIP network

Deploying Cisco Voice over IP Solutions provides networking professionals the knowledge, advice, and insight necessary to design and deploy voice over IP (VoIP) networks that meet customers' needs for scalability, services, and security. Beginning with an introduction to the important preliminary design elements that need to be considered before implementing VoIP, Deploying Cisco Voice over IP Solutions also demonstrates the basic tasks involved in designing an effective service provider-based VoIP network. You'll conclude with design and implementation guidelines for some of the more popular and widely requested VoIP services, such as prepaid services, fax services, and virtual private networks (VPNs).

FROM OUR EDITORS

The Barnes & Noble Review
Enterprises and service providers are gradually coming to recognize the compelling ROI case for VoIP. If you￯﾿ﾽre involved in network design or implementation, you￯﾿ﾽre either involved with VoIP already, or you will be soon -- probably with Cisco equipment. Now, there￯﾿ﾽs an expert-level guide to all aspects of the migration: Deploying Cisco Voice over IP Solutions, edited by Cisco packet voice executive Jonathan Davidson.

This isn￯﾿ﾽt a beginner￯﾿ﾽs VoIP book; if that￯﾿ﾽs what you need, consider Davidson￯﾿ﾽs Voice over IP Fundamentals instead. But if you￯﾿ﾽre already familiar with the basics, this book will bring you up-to-speed with the detailed guidance you need to design large-scale VoIP networks and implement the most widely requested VoIP services on them.

Davidson and his colleagues begin with key up-front design considerations: practical techniques for engineering and sizing traffic-sensitive voice networks; a complete methodology for eliminating the echoes that can plague VoIP networks; planning for QoS in diverse voice network environments; and Call Admission Control, for delaying calls when the network￯﾿ﾽs too congested to handle them properly.

In Part II, the authors walk through designing service provider–based voice networks: first, static dial plans built around Cicsco H.323 gateways; and then, long-distance VoIP networks. Next, they turn to network services: managed multiservice networks and packet voice VPNs; store-and-forward and real-time relay fax services; unified messaging based on Cisco￯﾿ﾽs uOne offerings; and prepaid services managed either through your internal network infrastructure or an Open Settlement Protocol (OSP) clearinghouse. If you￯﾿ﾽre planning or implementing VoIP in Cisco environments, this is an indispensable resource. Bill Camarda
