Goals and Methods
The goal of this book is to be a useful guide for network engineers and architects going through the various phases of planning and deploying a Cisco IPT solution. This book helps you to make the decisions that best suit a particular network scenario.The major tasks involved in each phase of the PDIOO methodology are explained with the aid of a case study that includes the most commonly deployed Cisco IPT architectures, telephony features, and applications. You can use the questionnaires in the appendixes to collect details about the customer's current network and to gather IPT requirements to propose the most suitable IPT network architecture and a detailed design.To keep this book concise, in-depth discussion of communication protocols is not included because this information is readily available in other books and in Requests for Comments (RFCs).
