Product 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.

sweet spot between technical details and broad overview, By
Amazon Verified Purchase(What's this?)
This review is from: Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization (Hardcover)
This book was exactly was I was looking for. I'm a CCSP, CCNA, CCDA, CWLSS/LDS integrating Cisco voice into a Cisco WAN/LAN environment. I needed a great overview of technology but with enough technical data to drill down into where desired. Kudos to Cisco Press and Kaza for doing this perfectly. My other IPT references were starting to age, so I wanted a newer resource. This one, published in 05, covers all the changes, standards, and advancements in the last couple years. It starts with 50 pages of protocols, specs, technologies and equipment. So you learn the basics of how a Call Manager based system works and some good Telco and signaling fundamentals. The authors then embark on a design-phase analysis of different scenarios. It's a little slanted towards clean slate installs and a consultants perspective, but I was able to glean plenty of info. Lots of default values, guidelines, and RFCs sprinkled throughout. Not much in the way of IOS/configs. Good and copious...

This will separate the successful from the failures!, By
This review is from: Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization (Hardcover)
Many of us have decided to put away our legacy PBX systems and install a VoIP based communication platform, and with all of the benefits clearly visible, we often jump into action without fully realizing the scope of what we are about to undertake. In a VoIP deployment, so many factors must be considered in the design, that often things are left out. In the deployments where QoS, switching infrastructure, and overall network design are ignored, you see problems with reliability and an overall bad taste left in the mouth of the end user. With proper planning, the problems experienced by these design flaws (or often lack of design) can be overcome, and the true glory of the VoIP system will be seen. Cisco has designed an awesome assortment of VoIP enabling technologies, that when used together can, and will, change the way we do business for the better, but only if you have a solid foundation of planning.The authors of this title, Cisco IP Telephony: Planning, Design,...

Practical Advice for Converting to IP Telephony, By Donald Mitchell "Jesus Loves You!" (Thanks for Providing My Reviews over 116,000 Helpful Votes Globally) - See all my reviews 
This review is from: Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization (Hardcover)
Switching to IP Telephony is one of those decisions that the CEO finds easy to make. Costs decline quite a lot and quality of performance is promised to be acceptable.Then the problem of implementation is turned over to those who will need to plan, design, implement, operate and troubleshoot the system. That lucky engineer will find that the Cisco solution is still a fairly limited one technically that requires you to make the right decisions . . . or you can end up with a system that doesn't live up to the promise that was made to the CEO. And you can guess who will get the blame for that. I read a fair number of the Cisco networking books, and I found this one to be more candid, detailed and helpful than anyone one I have seen. The authors wrote this book to explain what their clients had been having trouble with in implementing the first Cisco IP telephony solutions. That perspective allows you to avoid mistakes others have made... Read more |

Many of us have decided to put away our legacy PBX systems and install a VoIP based communication platform, and with all of the benefits clearly visible, we often jump into action without fully realizing the scope of what we are about to undertake. In a VoIP deployment, so many factors must be considered in the design that often things are left out. In the deployments where QoS, switching infrastructure, and overall network design are ignored, you see problems with reliability and an overall bad taste left in the mouth of the end user. With proper planning, the problems experienced by these design flaws (or often lack of design) can be overcome, and the true glory of the VoIP system will be seen. Cisco has designed an awesome assortment of VoIP enabling technologies, that when used together can, and will, change the way we do business for the better, but only if you have a solid foundation of planning.
The authors of this title have taken the steps to building a solid VoIP system and set them up in an organized structure that if followed, will provide a solid and stable installation and deployment. This isn't just another guide to walk you through the CallManager platform, but addresses design constraints of the entire VoIP system including infrastructure analysis, call processing, voice mail, QoS considerations, call flow planning, information on deployment of a pilot system, and acceptance testing processes. Once the platform is deployed, this guide will give you the insight needed to properly tune and maintain you system for many years to come. The many example forms in the back of the book will even walk you through the carrier circuit ordering process, voice mail system design, and even implementation readiness evaluation questionnaires.
I would highly recommend this title to anybody who has decided to install a VoIP system, even if you think you already have your bases covered. You can never be too organized or have too much planning when undertaking a project of this scope. If you follow the guidelines in this book, you will have a much greater understanding of what's necessary for a successful deployment, and you won't be one of those customers wishing they would have planned things better (as they fix their installation). If asked to rate the book on a scale of 1 to 5, with 5 being the best, I would rate this a 5, and essential to the library of any VoIP engineer.
