Book description
A guide to successful deployment of the Cisco IP Telephony solution
Real-world case studies from the Cisco design consulting engineers who developed the PDIOO process provide practical advice on all stages of successful IPT deployment
Concise understanding of the PDIOO phases enables architects and engineers to successfully deploy the Cisco IPT solution
Division of the process into PDIOO phases provides a logical and defined guide for network engineers and architects as they proceed through each of the phases in deploying the Cisco IPT solution
Includes detailed questionnaires for each phase of deployment in the PDIOO cycle—a great aid in understanding customer networks and requirements
Network infrastructure design, call processing infrastructure design and applications, and voice-mail system design are covered in depth
Cisco® IP Telephony (IPT) solutions are being deployed at an accelerated rate, and network architects and engineers need to understand the various phases involved in successful deployment: planning, design, implementation, operation, and optimization (PDIOO). On the road to that understanding, those involved need to collect information for each phase of deployment, and then follow through with the best architecture, deployment model, and implementation based on the data collected.
Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization is a guide for network architects and engineers as they deploy the Cisco IPT solution. With this book, you will master the PDIOO phases of the IPT solution, beginning with the requirements necessary for effective planning of a large-scale IPT network. From there, you’ll follow a step-by-step approach to choose the right architecture and deployment model. Real-world examples and explanations with technical details, design tips, network illustrations, and sample configurations illustrate each step in the process of planning, designing, implementing, operating, and optimizing a chosen architecture based on information you have collected.
In-depth instruction on each PDIOO phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution. This book also contains predesigned questionnaires and PDIOO assistance tools that help you determine the requirements of each phase of the PDIOO cycle.
Authors Ramesh Kaza and Salman Asadullah have been involved with Cisco IPT solutions from the beginning and have planned, designed, and implemented major IPT networks using the guidelines found here. Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization provides the step-by-step explanations, details, and best practices acquired by the authors while working with the top Cisco IPT customers.
This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
