The comprehensive guide to planning and implementing your Cisco IP Telephony system, as shown by the experts. Understand how to work through the different implementation phases of a Cisco IP telephony solution Plan your implementation with tools and guides from the most seasoned experts in the industry Avoid pitfalls in the process with best-practice suggestions and other tips derived from years of actual implementation experience Cisco IP Telephony: Planning, Design, Implementation, and Operation of the IP Telephony Network, is a guide for network engineers as they go through the deployment of a Cisco IP telephony (IPT) solution. Although an IPT system brings several benefits to an organization, understanding all the components of that system is necessary for a successful implementation. Engineers tasked with implementation must also keep in mind that the architecture they are installing must be scalable in the future. The authors of this book, Ramesh Kaza and Salman Asadullah, have taken an approach to address the questions that come to these engineers while planning, designing, implementing, and operating the Cisco IPT solutions. The deployment process has been divided into four phases: Planning, Design, Implementation, and Operation (PDIO). Each phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution. This book also contains pre-designed questionnaires and assistance tools that will help engineers determine the requirements of each phase of the PDIO cycle. This book is written by experts from Cisco with extensive experience in implementing these solutions. Readers are provided step-by-step explanations, specific details, and best practices acquired by the authors while working with the top Cisco IPT customers.
