There is no better path to the successful implementation of a new technology than to follow in the experienced footsteps of an organization that has already been there. The Road to IP Telephony tells you how Cisco Systems successfully moved its own organization to a converged, enterprise-wide network. You will learn the implementation and operational processes, what worked, what didn't work, and how to develop your own successful methodology. After presenting this topic to hundreds of Cisco customers, including Fortune 500 companies, Stephanie Carhee consistently encountered the same question, "If I decide to move to IP Telephony, where do I begin and what can I do to ensure that I do it right the first time?" Although the needs of every enterprise are different, some things are universal; planning, communication, teamwork, and understanding your user's requirements are as important as technical expertise. The Road to IP Telephony shares with you everything you need to know about managing your deployment. It starts with where to begin, including what needs to be addressed before you even begin the planning process, to building your project team. Key best practices are also offered to help you set the project's pace and schedule, get your users on board, identify a migration strategy, develop a services and support strategy, and work toward the final PBX decommission. "Cisco IT wants to share its implementation experience with Cisco customers and partners to aide in the deployment practices of new Cisco technologies. While conducting our own company-wide cutover, we learned a great deal about what to do and what not to do. This book shares our experiences." -Brad Boston, Senior Vice President and Chief Information Officer, Cisco Systems, Inc. This volume is in the Network Business Series offered by Cisco Press. Books in this series provide IT executives, decision makers, and networking professionals with pertinent information on today's most important technologies and business strategies.

Introduction to IP Telephony by Lawrence Harte Pdf

This book explains why people and companies are converting some or all of their existing (legacy) telephone systems from dedicated telephone systems (such as proprietary PBX) to more standard IP telephony systems. These conversions allow for telephone bill cost reduction, increased ability to control telephone services, and the addition of new telephone information services. Through the use of IP telephony service, companies can immediately reduce their telecommunication costs 40% to 70%. This book provides an overview of the different types of IP Telephony systems including IP PBX, IP Centrex and Internet Telephone systems. You will learn the key functional parts of voice over IP systems and how voice over Internet protocol (VoIP) systems work. Explained are the processes used to setup and control IP telephony service. The common IP Telephony protocols including session initiation protocol (SIP), Media Gateway Control Protocol (MGCP) and H.323 are described as well. You will learn how to connect telephones through data networks using adapters or by using telephones that plug directly into data networks (IP telephones). Discover what equipment and service choices you have and how they can affect your costs and service quality. Find out how packet losses and packet delays creates distortion and operational challenges and ways to reduce or eliminate these effects. Advanced telephone features that are only possible through IP Telephony are described along with how customers can setup and configure their equipment through the use of self provisioning web portals. Learn about the different types of services, their typical costs and some of the hidden costs of IP Telephony and ways to reduce or avoid them. Some of the most important topics featured are: .The different types of IP Telephony systems .Functional parts of VoIP systems .The processes used to setup and control IP telephony service .How to connect standard telephones through data networks .What choices you have and how they can effect your service quality .Advanced telephone features that are only possible through IP Telephony .The different types of services and their typical costs .Some of the hidden costs of IP Telephony
