Telephony Books

I ordered the book at Amazon because the shipping cost was much less (to Europe) than if I would have ordered the book from Cisco.

This book covers most QoS materials used in Cisco 642-642 Exam helping candidates get to know about QoS theory and Cisco router and switch configuration for several networks components (LAN, WAN, Service Provider). With small errata you can get at Cisco Press makes this book an excellent resource for QoS students.

I was floundering in QOS in my lab preparation, so I picked this book up on the advice of an architect I work with. Since then I've seen it recommended by many very senior engineers, and I know why. If you have some hands-on with modern QOS (Modular QOS CLI...) you will get a *lot* out of this book. I poured through it in about a week and it filled in a ton of gaps. Great writing style, about as much a "page-turner" as you can find on a subject this dry.

I really appreciated the overview chapters, as I managed to get a patchwork knowledge of QOS, and the follow-ups were sufficiently detailed to give solid depth of understanding. Also, don't toss the CD out, it's not just some goofy test engine for the VOIP test. It has the first edition's chapters that were cut out. If you're working toward the CCIE R&S, this is really important as the CD contains the Frame Relay Traffic Shaping chapter.

If you're doing QOS or studying for the CCIE R&S, read this cover to cover, at least twice. Good stuff all around. I also have "End-to-End QOS Network Design" as well, but haven't gotten to it yet or I'd comment on the differences.

This is an excellent book for QoS. I recommend this for anyone interested in mastering QoS.

Well I originally bought this book to help study for the 642-642 QOS exam. I certainly used it for that and then some. It covered all of the exam topics pretty well and for me was an easy read. I might add that I ended up scoring a 905 on the exam, so it can be done!!
What I didnt realize was that I would use it even more after the fact for a reference on deploying QOS for customer networks. Definitelt worth the money for this book.

This book may be overkill for the CCIE R&S track, but if you want to UNDERSTAND VoX and related technologies, this book is awesome. Now I feel like jumping over to the C&S track.

I haven't read the whole book, I'm 50% done, but the first impression is that there's too much theorical information, but I think we really need that. That's absolutely a wonderful resource. After reading some parts of this book I was able to setup a successful VoIP connection. This book also helps to understand the codecs, problems you can find, etc..

Good choice!

I bought the 1st edition back in 2000 and since then it is still the most frequently visited reference when I helped my clients to build VoIP networks. It was written completely from a hands-on engineer perspective, aiming at getting the job done. So you would expect very detailed description on signaling ..., design scenario, IOS programming and trouble-shooting in debug mode. My favourite parts are the coverage on Echo, dial-peer programming and SIP. After finishing a SIP network project, I'm just amazed how a book in year 2000 can provide such a farsighted material.

Keagy brings up a lot of important issues a level deeper than most books on the subject. It is a great reference book but most sections are readable all the way through. If you are moderately technical or very technical you'll get something out of this book. The more books you buy the subject the more you'll appreciate this one for its attention to detail and clarity.

I'm a qualified Cisco CCSI/Microsoft course trainer, and needed a book to get me started in the area of Voice networks in a reasonably technical, practical and non-trivial manner. I definitely found it in this book. Keagy provided an excellent overview of the operational details of voice networks & SS7, and married this well to Voice-IP networks and WAN technologies. It was refreshing in that, although Cisco oriented, you are thankfully spared the worst of Cisco's product placement sales pitch (for which you'd need the CVoice book). In fact I can concur with other reviewers in that Keagy's obvious practical experience, mature expressive style with plenty of useful figures/illustrations (which I personally as a trainer really appreciate) and ability to impart knowledge in an enjoyable worldly manner shine throughout in the text in a style that is remniscent of Doyle Routing - I look forward to more books by Keagy (hopefully his wife will let him :o)
Although you can buy books that cover the individual chapters in more detail (Keagy provides numerous references), this single tome is a must for anyone breaking into the trendy area of Voice from a predominantly data networking background.

This a very good book. Even the examples are fully configured.
It has a good balance of theory and practice, wich is sometimews dificult to find in technical books.

Best Cisco book in GW and GK (and the only one by now).
Recommended.

An excellent book! but if the author can put all the configurations online, and make the scinarios more realistic with more practical exercises, this would be a masterpiece in this area. It is much better than other Cisco CCVP books in many respects. Thank you, the authors, who took readers into consideration when writing this book!

I picked up a copy of "Cisco Voice Gateways and Gatekeepers" to use as a study guide for the Implementing Cisco Voice Gateways and Gatekeepers (642-453 GWGK). This book was enormously helpful in successfully passing the exam. With that said, this is not an official Cisco Press exam study guide, in fact it cover much more, and was also beneficial to me in passing the CCIE Voice written.

As with most Cisco Press books, the opening chapter covers some basics, in this case the basics of Voice Gateways and Gatekeepers, as well as a high level review of gateway protocols and deployment scenarios.

The subsequent chapters jump right into the meat of the material. Each ensuing chapter covers each topic, such as H.323, SIP, MGCP, Dial Plans, and SRST with great depth and clarity. The book if full of very detailed and comprehensive sample configurations and debug outputs. Finally, the examples throughout the book are based off of the same case study network that is introduced in the opening chapter. As I consider sitting for the CCIE Voice Lab, I anticipate that I will revisit this book again and use the case study in my home lab.

I highly recommend this book to any looking to learning more about Cisco IOS Gateways and Gatekeepers, studying for the CCVP, and/or preparing for the CCIE Voice!

Mark G. Reyero, CCIE 12932

As a person studying for my Voice CCIE, this book is invaluable. It covers a wide range of topics in a coherent, well-articulated fashion. After perusing this book, I finally figured out exactly what an IPIPGW was and how exactly it worked with a VIA gatekeeper.

If you are studying for you Voice CCIE, do yourself a favor and pick up this book.

This book is intended for network engineers, IP Telephony engineers, and Telco engineers who are tasked with the installation, configuration, and maintenance of VoIP and IP Telephony networks. This is an intermediate level book and that the reader understands IP networking and at least is familiar with the Cisco courses: CVoice, CIPT, QoS, IPTT. These imply a basic understanding of VoIP and time-division multiplexing (TDM) voice fundamentals, the basic concepts and configuration of basic IP voice routers and Cisco CallManager basics.

This book is not so much an Exam Cram as a more traditional reference book. That is not to say that it doesn't cover the material that will be found on several Cisco certification tests. It gives a firm foundation in the complex VoIP networks that in which Cisco specializes. Obviously this book covers Cisco equipment, but as Cisco is the major manufacturer of such equipment as well as providing for the certification of workers in the field, that's not a bad place to start.

This book has the advantage of a very good writing style by the three authors. This is important as I don't find computer books to be nearly as much fun to read as say a good sci-fi novel.

Top Marks for this highly readable and clear intro to Voice over IP. The subject matter is dealt with in reasonable detail and the author achieves great clarity in explaining difficult technical concepts. He also delves a bit into the history and background which also helps to put the subject matter in context. He even adds a small example of how to go about dimensioning a VOIP network at the end of the book.

Aimed specifically at designers of public telecommunications networks, this easy to read book provides practical and useful hands-on information. Where necessary, topics are covered in great detail. For example, 120 pages are dedicated to H.323. Softswitch architecture and programming are covered, and 55 pages are devoted to discussing Quality of Service issues.

We believe this book to be an essential read, and recommend it highly.

Great book on VoIP, still emerging technology. It did a great job in explaining concepts related to QoS such as RSVP, DiffServ and MPLS. Right from basics such as IP, UDP, TCP and various coding techniques you will find great explanation to each and every item. If you are interested in knowing about VoIP or you if u wanna work on VoIP this is the ONLY book you need. There is very detailed and neat explanation related to MGCP, MEGACO, SS7 and SIP too. The only thing that i felt lacking is testing of voice quality both subjective and objective and how they could be done. No doubt in giving 5 *s to it, great job!

This book does a very good job of giving an introduction to the VoIP world. As a professional in the telecom domain, I found this book very useful. Application of VoIP to telco domain as in the case of softswitch architecture for backhaul and the QoS issues that carriers have to deal with is also well covered at a good amount of detail. The book also provides detailed discussion on the protocols. However, I skipped passed these sections and unable to comment if such material was covered well.

Overall - a very good book. Highly recommend it.

I serious think that I should not write this review since I do not understand half of this book, but then again, I have read this and also Cisco Intergrated Voice Data and can in some way be a poor/insufficient abeit enthusastic tour guide. I have noticed other reviewers describing this book as great - but I do not think this book is comparable to monumental classic like Jeff Doyle or Kennedy Clarks books on Routing and Switching - where they display in-depth knowledge on the topic plus an ability to explain thing in the clearest possible way. I rate this book 5 stars for the sole reason that the author do appear to have an overwhelming knowledge of computer telephony - although I cannot quite judge whether they are technically accurate or error free - and has taken his valueable time off to write them down and share with us. While the author definitely has the kindest intention of making it "understanable" to even the not-so-technically-advance group of reader - as is evidenced in the way he start off this book by explaining why bother with IP telephony, and why TCP/IP is inherently unsuitable for IP telephony - I suspect that when it come to harder topics like H.323, SIP etc - there is simply no way or no time to find a more reader friendly way to present it. In the end it is a tough read - so tough that I will have to put it aside for a while as you need to be in the highest state or mental agility and strength to make hard yakka through the book. Nevertheless, this book is a useful reference - and for topics that this author decide not to include - check out Cisco's Integrated Voice and Data.

This is an excellent walkthrough of Skype all the way from getting started to using special phones and other VoIP appliances. I'm impressed by the depth of the coverage, and the quality of the writing. This is easily the best book I've seen on Skype.

"Skype Me" is an excellent book for both beginners and advanced users of this free Voice over IP (VoIP) application. With easy instructions for downloading, installing, and using on any system, Skype is remarkably effective, but simple. It allows you to talk by voice in computer-to-computer conversations, conferencing, and even video capabilities with the necessary security features to protect your conversations.
This "family and friends" phone plan could put the phone companies out of business - except to bring us the DSL line. I've seen my wife use Skype to conference with her local partner and their Australian customer.
While basics are great, there's plenty here for the more advanced users including using Skype with other hardware and software (eg, wireless devices like cell phones). The authors also walk you through the security aspects of Skype - absolutely necessary these days.
Overall, a great book to own and keep handy as a reference for expanding your cyber knowledge.

Skype is a simple to implement Voice Over IP (VOIP) solution for the average computer user. If you are tired of long-distance charges, want to be able to tell when someone is online and you can call them, chat in a secure, encrypted environment, engage in video chatting with others, or call someone who has a regular phone system at substantially reduced rates then Skype may be the product you need. This book covers installation, configuration, and basic usage as well as configuring advanced features and personalizing your Skype. While this is useful, I found the software to be so user friendly that it was easy to figure out most of this by just exploring the basic options of the system. That being said Chapters seven and eight were well worth the price of the book by themselves. These chapters cover software and hardware add-ons that can greatly enhance your Skype system and make it work the way you would like it to. The final two sections of the book cover setting up Skype in a business environment and writing custom interfaces to it by accessing the Skype API. This section includes important information on how to set up Skype behind a firewall. Skype Me is a highly recommended purchase and a great way to access the VOIP world for anyone with a computer and good Internet access speed.

Skype Me! is the perfect introduction to Skype for users of all skill levels. It could serve as an example of how to write a product-centric book that delivers real value. The text is well written, clear, and focused. The material becomes progressively complex as the reader moves from learning about Skype, to installing it, to using it, to extending it into areas I hadn't previously considered. Anyone who wants to get the most out of Skype should read Skype Me!

I believe Skype is an incredibly intuitive and simple piece of software. I didn't spend much time with the first four chapters of the book, since I think the ease of installing and using Skype is one of its main attractions. Beginning with Ch 5, however, author Michael Gough started expanding my sense of what could be done by Skype. With advanced features in Ch 6, software add-ons in Ch 7, and hardware accessories in Ch 8, I was entering new territory. The material was well-covered.

I have no real concerns with Skype Me! I have a minor issue with the author's suggestion on p 270 that using a 900 MHz cordless phone is a sign they need to be "upgraded". A 900 MHz cordless phone is a great way to avoid interference in the 2.4 GHz range used by modern wireless networks and newer cordless phones. I would have also liked some expert commentary by a security professional regarding controlling Skype in the enterprise.

Overall I highly recommend Skype Me! I would feel comfortable sharing this book with my parents as a way to encourage them to try Skype. I would also share it with friends who want to tinker at the edges of traditional Skype usage.

Skype Me! is a book that everyone needs to have. It's less technical than Skype Hacks, which makes it more accessible to non-techies. Gough starts off with basic lessons about VoIP, Peer-to-peer technology (as it's used in VoIP), even Skype security. These basics will help anyone who is looking at setting up Skype in their home.

Installation is covered in Chapter 2. Gough gives detailed instructions on testing individual computers setups to make sure that Skype will work properly, and shows how to install Skype on Windows, Pocket PC, Mac OS X, and Linux. Then, in chapter 3, he covers the basics of using Skype.

Gough spends a lot of time on using Skype from Pocket PCs, even Pocket PC cell phones and smart phones. This is something I'd never thought about, honestly - my cell phone bill is pretty small, and we've got a good family plan. I can see where people who use a lot of cell phone minutes each month could save some money.

Skype Me! also goes into detail when it comes to implementing Skype in a business setting. This is one area where I think that Skype is being under-utilized. There's a perception that Skype is for home users, but isn't powerful enough for enterprise use, but it's clear that Skype is a lot more powerful than people think. There's a lot of potential for business use - especially when you look at the call center hack that I mentioned in the review of Skype Hacks.

One disappointment I had with Skype Hacks was that it didn't really talk much about the Skype API. Skype Me! does this in chapter 14, and goes into enough detail that people with a computer background will be able to take advantage of the API in customizing their own installation of Skype. Skype Me! also goes into more detail in discussing the various Skype-enabled devices that are available, or will soon become available. Gough includes mini-reviews of a lot of popular Skype hardware add-ons that will make your Skype experience much more pleasant - and productive.

For new users, Skype Me! is a valuable addition to their library. The fact that Michael Gough is the guy who runs SkypeTips.com and is constantly adding material at that site is just another reason to get this book.

CiscoPress's "Cisco DQOS Exam Certification Guide" by Odom is a best-of-class book. The book is not for the meek - weighing in at over 850 pages, the book is a sizable investment of time and energy to properly appreciate. While the book was mainly written to be utilized for a few QoS exams, I'd expect to see this book on the bookshelf of many CCIEs or CCIE wannabes (including myself).

The beauty of this book is that it covers QoS in a depth that is not equaled elsewhere. For example, the book's first chapter, simply an overview of QoS, is almost 80 pages (some overview)! The first chapter succinctly describes the differences and nuances of the enemies of QoS - delay, jitter, bandwidth and packet loss. The second and third chapters do a great justice at trying to explain the dizzying array of tools available to adjust QoS - the different classes of tools and the differences between classification and marking. And so forth..., each chapter does a great job at explaining the mysteries of QoS.

Of course, with any book of such complexity, typos must be expected. Two typos that I noticed are:
-on page 333, I believe the correct Bc should be 93.75ms.
-on page 456, FRED can match on layer 4, not layer 3 protocols

If I had a `Top 10' for books that I feel would be necessary for the CCIE, I would place this book on the list. I have not been able to find the same explanations for QoS on Cisco's website or in other networking books.

I give this book 5 pings out of 5:
!!!!!

It seems that everybody likes this book so I won't waste your time writing another long review.
This book is by far the best Cisco book I've read, and I've read a few. It's full of detail and a very very good starting point for QOS.

The team of Cavanaugh & Odom have hit a homerun here. This book has everything; Sex, Politics, Intrigue, Suspense, Greed, Betrayal and Redemption. Well, okay, it has none of that. But, it does have everything that the Experienced Networker could want to know about Quality of Service, and it's role and implementation within today's rapidly converging internetnetworks. The authors have proven to be knowledgeable, insightful and easy to understand. And, while this book may seem "overly long" to many, it strives to give fairly complete coverage of this important matter regarding today's internetworking environment. This is a very important point when your seeking to spend some "quality time" with a Cisco certification exam (not mention some quality cash on an exam).

Cavanaugh & Odom have moved beyond the normal course of just re-editing Cisco TAC web content for bound, portable consumption that is the hallmark of many of Cisco Press' previous publications. While the layout will be familiar to previous C.P. readers, the actual format and content presentation is fresh. Each chapter's order and flow strongly adheres to the tried and true, but Illustrations, Diagrams, Scenarios and Examples are not just simply reprinted fare from Cisco's website. Each chapter's content is easily on par with all other Authors/Publishers that are typically quoted as being "easier to digest and understand". Even the book's index is surprisingly extensive and comprehensive, and misses very few important items. When the working examples actually are repackaged from Cisco's web content, the explanations and follow-throughs are incisive and accurate. Knowledge and understanding can be gained from every page without overkill or excessive repetition.

Any exam candidate seeking an in-depth review and preparation for the Cisco QOS or DQOS exams will find this book a treasure trove chocked full of the expected scenerios, examples and practice questions. All networking professionals should strongly consider stocking this in their personal reference collection for handy lookups to otherwise difficult QOS problems. However, I caution one, if you're seeking a quick and simple introduction to QOS, or looking to "break into" or "get their foot in the door" of internetworking, you should go elsewhere. This is definitely not the kiddy end of the pool. But then again, it certainly won't require the deep sea background of a CCIE either. This manual may start with the foundations of QOS but it very quickly ramps up to a professional-level internetworking reference. This is a book that goes beyond the classroom and heads straight for the real world.

As my industry and workplace move further towards voice and data "Convergence", this book has quickly become my working cookbook for smoothing out tough QOS implementation questions. And, It shall remain an important part of my desktop reference library for a long time to come.

I recently read the book titled "Cisco DQOS Exam Certification Guide" by Wendell Odom, ISBN: 1587200589.
This book takes the user through the topic of Deploying Quality of Service in Cisco networks to a new level of knowledge. QoS has become one of the hottest if not the hottest topic in enterprise and medium size business networks. The ability to control traffic based on its priority and the ability to prioritize the traffic based on any number of criteria has become a required skill in today's marketplace. To Quote from Cisco's Web Site "Quality of Service (QoS) is an essential element to building a flexible, accessible, and efficient network. Its role in multiple technologies underlines the need for most networking professionals to master the features that implement QoS" The advent of Cisco's AVVID network and the proliferation of IP telephone services and applications along with the advancement in Video Conferencing and Group Collaboration software have created an unprecedented need for Quality of Service implementation. This book is filled with examples and thorough explanations of many complicated and essential configurations. The authors display a thorough knowledge of this sometimes difficult and always challenging subject. There are numerous charts and graphs to help aid in understanding the concepts presented. This book takes the reader step by step through configuration of all of the commonly use techniques and gives the user a good understanding of not only how to enter the commands but also what the commands do and how they interact. The topics covered in this book will give a CCIE R/S candidate essentially all of the skills needed for the QoS portions of the CCIE Practical Exam. The book covers all of the currently available traffic prioritization and queuing methods in a high degree of detail. It is, I think, geared towards an audience of knowledgeable professionals who already have some knowledge in the area of QoS. The book provides a reader with the tools necessary to implement virtually any needed QoS features in his/her own network. I would rate it as a MUST HAVE reference for anyone who might be required to implement QoS in a Cisco environment. This is a winner for Cisco Press. It proves once again the commitment to excellence of Cisco Press and delivers a book that is very useful to anyone involved in the implementation of the topic it covers. The authors have taken a difficult subject and broken it down into manageable chunks. At the end of the day the user will have a good understanding of the broad topic of QoS and have the tools necessary to implement it in a Cisco environment.

Let me just start off by saying that I wish I had Wendell Odom's Cisco DQoS Exam Certification Guide a few months ago when I was studying for this exam. I had looked at a number of other Cisco Press and non-Cisco Press books and could not find one that adequately covered the topics in the exam. This one covers all of them and more.

The book starts off by listing all the exam topics that will be covered in both DQoS 9E0-601 and QOS 642-641 exams and then explains how to interpret those often nebulous expectations. Do not get me wrong. It does not give you a blow by blow of what is on the exam but rather informs you of how test makers come up with course objectives and a method to use in studying. I found this very helpful. In fact, I wish someone had taught me that as a freshman in college.

If you are familiar with Cisco Press Exam Certification Guides you will not be disappointed in the familiar format. Each chapter starts with an overview and "Do I Know This Already?" quiz. I always find these helpful in determining my level of knowledge on a particular subject and those areas I need to study.

It then proceeds to the meat of each chapter. They are filled with many useful diagrams and tables that do a wonderful job complimenting and expanding Odom's covering of each chapter. There are plenty of switch and router configurations that also provide help in giving real life examples of how QoS is implemented.

Each chapter then wraps up with an excellent Foundation Summary and Q&A section. Answers to the questions are found in an appendix in the back of the book.

In general I found all of the topics covered as well, if not better, than the DQoS class I took to study and pass the test. In particular I found the first two chapters great in providing a great overview of QoS, its architectures and tools. I have used Odom's example of bank teller lines, with a number of customers, to provide a way of explaining the difficult topic of QoS and it quickly resonates with them.

I also found the last two chapters on QoS Design and LAN QoS very useful. The LAN QoS chapter provides information on the 3550s and latest Modules/Supervisor Engine cards for the Catalyst 6500 and 4500/4000. I have already used this information as a resource on a project. The design chapter has also been useful in helping me "flesh out" customer's goals and providing design recommendations based upon those goals.

In conclusion, I always feel that for a study guide to truly be useful, it must have some use after the exam. Wendell Odom's Cisco DQoS Exam Certification Guide certainly does that well. It will not only be sufficient in providing you the information that you need to study for and pass the test, but it will certainly be useful as a quick reference guide on many of the topics covered. I plan on having it with me from the project planning stages to the optimizing and troubleshooting stages (although if your good and follow his teachings on the former you probably will not have much of the latter). Thanks Wendell for another well written and useful book.

A very good reference guide for any new/existing cme/cue deployment. Specifically the sample config guides were very useful. Overall this book is well written.

Cisco IP Communications Express: CallManager Express with Cisco Unity Express (ISBN 1-58705-180-X) is an all-in-one resource for configuring, managing, and troubleshooting the Cisco CallManager Express (CME) solution. It is almost 900 pages and is well organized into five parts: overview, feature operation and applications, administration and management, maintenance and troubleshooting, and appendices. If you are involved in configuring or maintaining the Cisco CallManger Express, this book will provide you with all the information you need to get your work done.

Cisco CME is an integrated solution offered by Cisco for meeting the IP telephony needs of small businesses or branch offices. The CME solution, which consists of the call processing feature and the voice mail feature, runs on the Cisco routers ranging from the 1700 series to the 3700 series and beyond. Whereas the CallManager suite offers centralized approach to building out an enterprise wide VoIP network, the CME is meant to serve the needs of smaller businesses or to integrate seamlessly into the larger, enterprise solution.

The book is well written and starts out with a high level architecture of the deployment scenarios for CME. The second part gets into the features and applications side of the solution. This part is where the crux of the book lies. It presents a detailed coverage of the commands used to configure the CallManager solution under various scenarios such as implementing different call features, integrating VoIP with PSTN, and deploying CME as part of a larger CallManager solution. This part presents a thorough coverage of Unity Express (UE), the voicemail module of the CME. The third part relates to the management of CME. Particularly useful in this part is a real-life configuration example as it illustrates and brings together a lot of the material covered in the earlier part of the book. Part four gets into the essential topic of troubleshooting the CME solution. It provides useful tips and solutions for common problems found in deploying the call processing and voice mail aspects of CME. This is definitely a very useful section of the book. The last part, the appendices, has reference materials and scripts used in the book to make daily tasks easier etc.

One of the strong points of the book is a multitude of sample configurations. The authors provide sample configurations throughout the book to help illustrate the concepts being presented. This sample configuration goes a long way if the reader has the task of actually configuring CME. The other strong point of the book is the depth of coverage given to each topic that is discussed. With the exception of a handful of topics (one in particular which I'll mention), the book never glosses over any topic; rather it covers it in detail, ensuring that most aspects of the topic are addressed. The exception to this was the coverage of the D/A module(s) used for attaching analog devices to CME, such as a fax machine. Given that analog fax machines still constitute a critical part of any business, I would expect this topic to be covered in detail. However, I found that no configuration examples were provided on how to configure this in the CME suite.

In summary, this book is a great all-in-one reference for configuring and managing CME. I would highly recommend it to any professional tasked with working on Cisco's CallManager Express.

overall this book is very good. I like the examples it presents to make thing clear, and also the broadness of topics it covers.
Since Cisco IP Telephony evolves so quickly, I wish Cisco will release newer editions with updated technologies. in particular I was hoping this book should contribute some to SIP and its deployment in UCME environment.

I've used this book as a main reference for my first complete implementation of CCME and CUE. I said "main" reference instead of "only" reference, because there are few small gaps to be filled by Cisco on-line documentation, but the deficiencies are too small to justify anything less than 5 stars. Additionally, there is a lot of general (IP and traditional) telephony information so even a relative beginner, after reading this book, will be able to intelligently interview future users (Chapter 5 is simply brilliant!), design quite complex system with many fancy call features, and even create scripts for quite sophisticated Auto-Attendant options. Certain concepts are not explained in complete detail (for example dial peers or voice ports), but deeply enough for the needs of CCME.

A must have book


This book is a great tool for full and complete understanding of Cisco's IP Communication Express. The structure is geared to first provide a foundation with an overview, then moves into design and implementation the book is organized into different parts that provide great coverage of all aspects.

Part I starts with introducing IP Communication. The coverage begins by taking you on a journey into what Cisco IPC is, the benefits of IPC, and the architecture of IPC networks. The one thing you notice is that the authors took great care in organizing the chapters. Each chapter is well written and easy to follow along. This makes the book a great choice as either a first learning book or as a refresher book for experienced professionals looking to augment their knowledge. One of the first chapters shows you the features and functions of the various gateways, WAN interfaces and IP phones available for use in an IPC network. This allows you to pick the best equipment for your particular solution. I believe this is great because it allows you learn some features of the product in order to decide if you would like to research it further; this helps streamline the process of design and political issues. Another section of the Part 1 goes over the architecture of IPC. You will learn the ins and outs of what happens at a low level. You will learn a-lot of core information; get an introduction to equipment and technologies that can be utilized.


Part II of this book is where the fun begins. Chapter 4 goes over the IP phones in more detail. You are taught about features and how to configure the individual phones. The chapter is short and to the point. Chapter 5 is an incredible book where the engineers' ears will perk up. Call Manager Call processing features are presented in this chapter. The topics here include hunt groups, call parking, shared lines, intercom, paging and much more. I really like the configurations and examples in this book. With this chapter you will be able to quickly implement the CM features.
The next chapter deals with Connectivity to the PSTN. The focuses in this chapter are signaling and how to handle the inputted digits. One of the only faults I think with this book is that chapters 5 and 6 should be swapped.

Part III and IV cover Administration, Management, Maintenance and Troubleshooting
Now is really where the techies cheer up. Here is all the goodies on how to setup CME, UE, and what to do if problems arise. The gold mine is located in these 2 parts.
These chapters provide the reader with detail and examples to help reinforce all that is being explained.

I don't want to spoil this book or be long winded so I will say the remaining pages of this book are well worth the read. It covers everything you need in order to obtain a solid understanding of Cisco's IPC. There is no area that isn't covered with attention to detail. The authors provide quality information that is very useful in all areas of understanding and implementation of Cisco IP Express. The reader will come away with exceptional and relevant knowledge to do anything needed with IPC. I got this book to help augment my 4+ years with Cisco Voice products, I feel that it did help cement my knowledge and also taught me quite a few new things.

Developing speech applications is not easy to master. Even with VoiceXML becoming more widely adopted, there are a lot of intricacies that that a developer must understand. This book will provide you with a solid foundation to become an effective speech application developer.

The book did very well in presenting the limitations of the current speech recognition technology (dialog design, large vocabularies, promtp design, etc.) and made suggestions on how to overcome such problems in specific situations.

When this book came out a couple of years ago it was the first and only book on designing speech recognition systems. It was very valuable then, but now more books are available that cover the same information and more, for a lot less money.

This book is simply the best for your bookcase if you are a voice dialogue designer. I would strongly recommend it to novice and expert alike, especially for those learning VoiceXML for the first time, or working with it day to day.

Grounded in hours of human-computer experiments, and a multi-disciplinary approach to user interface design - this book is a rare combination of a careful ear for human language and dialogue, extensive engineering experience, and pragmatic knowledge of the strengths and limitations of current voice recognition technology.

The second edition has brought it bang up-to-date. It cuts through the hype that has always surrounded each successive generation of voice technology - focussing always on the building of robust useable interfaces which work with the user rather than against them.

This book is so well organized and articulated it's bound to be of value to anyone doing ASR application development. My own experience in voice response runs from end-user representative to application designer and I found every chapter enlightening. In this second edition of Bruce and David's ASR style guide, I believe the end users will find the new sections on voice portals and managing your voice talent of particular interest. And all users should take particular note of the expanded discussions of usability testing and performance reporting.

I found the first version of How to Build a Speech Recognition Application so useful that I actually took the time to compared the new edition, page for page, with the original. That was a relatively easy task, because the authors retained the original section numbering wherever possible. My comparison showed that the original guidelines have been substantially updated, based on continuing research and the hands-on experiences of both the authors and other acknowledged experts. In addition, I believe the new sections and expanded discussions of critical design considerations are going to prove valuable to both novice and seasoned developers.

In short, developing effective telephony dialogues is a complex, rapidly evolving and downright expensive task. Given that reality, every development team ought to have at least one copy of this landmark style guide.

Author, Bruce Balentine's goal with How to Build a Speech Recognition Application is to produce the Strunk and White of speech recognition. An electronic musician and composer, Balentine was a pioneer in the speech recognition field. The text's examination of the problems of navigation from human perception to machine recognition give comprehension to even the layman. The book is well organized and structured with the +,/,- system which allows a novice to follow. According to linguist, Dr. John White, the first chapter could stand alone as a treatise on the dynamics of the human speech interface with the machine.

This book has definitely provided me a solid background in H323.
In addition, it is a very useful reference, for example, I was
able to follow the call setup and media setup packet flow of an IP phone captured via a protocol analyzer(ethereal), thanks to the very clear illustrations. This is definitely a must for network administrators/managers considering a multimedia network implementation.

This book provides a highly-technical in-depth look at H.323. Aside from reading a few whitepapers on the Internet, this book was my first real introduction to H.323. The subject itself is rather complicated to a new-comer, but this book provided a high level of detail without losing the reader. While it is no "for dummies" book, it is clearly written so the person with the right background (i.e. with a firm grasp on networking and TCP/IP) can pick it up and follow along. So why 4 stars and not 5? It realy has to do with the architectural graphics. In some of the information on the Internet ... , there are some really good architectural graphics that depict H.323. I think the book could be even better if the authors included such an approach.

This is a treasure of H.323, VOIP information! Excellent protocol information. This is no paper weight, gathering dust! I use the book and I'm glad to have it on my shelf.

This is by far the most comprehensive book on the market. I agree with the previous review, IP Telephony with H.323 is for advanced uses and a great reference guide as well. I highly recommend it if you want a thorough understand H.323 and IP Telephony, however, if you wish to learn about a particular subject, for example QoS or MPLS, this book will not provide enough detailed information (check out Cisco Press).

Must buy!

We are in the middle of a project that uses H.323. Everyone in the group likes the book. We bought a couple of hardcopies.

I decided to try the electronic version, mainly because I could immediately have access to it. It was a mistake.

First, it required me to update my Acrobat Reader to 6.0 (AR6). Then, to read the book I had to register/activate AR6. Two problems right here: as far as I could tell, you can only register AR6 if you have a .Net Passport. If you don't, tough luck. Go to MSN and get one. I happen to have one (from my Hotmail account), so I thought "no big deal." It turned out to be a big deal. After you enter your Passport login/account, it asks for more personal information (name, email, etc.). I don't like to give out this information unless I have to. Reading a book is not a good reason IMHO.

After all that I decided to cancel the AR6 registration and to return the book. You cannot return the e-book (or I could not find a way to return it). I'm sure Amazon states that clearly, but I probably missed it in my rush to get the copy.

I would gladly recommend the hardcopy, but go for the e-book only if you don't mind all the hoops.

This book offers good strategies for implementing VoIP. It covers the feasibility studies required and pre and post evaluation of the network. Technical details are covered well but the most important aspects such as QoS, SLA's are explained in some sort of details, which is an important area when dealing with VoIP.

I used this book as one of my main reference in my final year project with UOL BSc in CIS.

I recommend this book not just for Engineers, Technicians, Managers and IT staff, but also for anyone wishing to learn about the basis of VoIP.

As one of the lead Network / IP Telephony engineers for my employer, GE IT Solutions, I was excited to learn that Cisco Press had published a book addressing the business and project management aspects of Voice Over IP (VOIP). I was glad that I picked up "Taking Charge of Your VoIP Project" by John Walker and Jeffrey Hicks (ISBN 1587200929) and I highly recommend the book to any IT decision maker, project manager, or lead engineer considering VoIP technologies.

The authors clearly indicate in their preface that the book is not a technical "how-to" manual for VoIP. Rather, the target audience is "chief information officers and information technology managers who choose to deploy VoIP in their organizations". The book opens with an overview of VoIP terminology and acronyms. For the most part, the discussion remains at a high level, although the details on IP packet headers probably could've been scaled back, given the target audience. Chapter 2 delves into the business drivers for moving to VoIP, such as convergence and ROI.

Chapter 3, Planning for VoIP, was a particularly helpful section in relation to my job functions. The chapter does a excellent job discussing the value and importance of planning and design for VoIP networks, a critical piece of any VoIP project that I feel customers (and even some vendors and implementers) often overlook. In fact, if it weren't a copyright violation, I'd probably copy the entire chapter and hand it out to any of my existing and potential VoIP customers. Better still, I'll by them a copy of this book.

Subsequent chapters of the book's focus continue to balance the business considerations with the technical aspects of VoIP. Topics of discussion include finding the right implementer, QoS tuning, ongoing VoIP Management, SLAs, and security considerations.

As mentioned earlier, I highly recommend the book to any IT decision maker, project manager, or lead engineer. I've encouraged many of my non-technical business colleagues at GE ITS to read "Taking Charge of Your VoIP Project". In fact, one of our Six Sigma quality leaders engrossed herself in the book and gained an very comprehensive understanding of both the business and technical aspects of VoIP. Next thing I know, she'll be pursuing her CCIE!

I recently read the book titled "Taking Charge Of Your VoIP Project" by John Q. Walker and Jeffrey T. Hicks. ISBN: 1587200929.
The title is a great reference for understanding VoIP technology and helps identify the many aspects that one must consider for a successful deployment of Voice over IP. Reading this book ahead of time will empower the reader with the lingo, technology and solutions to be effective when leading a team.
The book starts out by giving the reader an understanding of the basic technology concepts surrounding traditional voice networks, or Public Switched Telephone Networks (PSTN) and then goes right into the basic technologies that allow Voice over IP (Data) to be a viable alternative to the traditional phone networks.
Chapter 2, Building a Business Case for VoIP, gives the reader good information to ponder over and helps identify purpose for building a case for a VoIP solution.
The next chapter, "Planning for VoIP" is one of the larger chapters and for good reason. After all, anyone in business knows that planning determines whether the project will go smoothly with little surprise or whether it's a disaster. In this chapter you'll learn about reliability, call quality assessment, and over all VoIP readiness assessment, among other things.
Another great chapter is Chapter 5, "Quality of Service and Tuning". Probably one of the biggest challenges that an organization will face. QoS is challenging due to the complexity of a true end-to-end QoS solution in an already complex data network. Accomplishing QoS requires in-depth knowledge of the existing data network. Furthermore, the communication to others on the team of what it's going to take to get the network "up to snuff" to support VoIP will be a task in and of it self. It makes ATM technology look quite attractive. The chapter has quite a bit of detail; however the authors don't drop the reader over the deep end of the technologies.
I would recommend this book to those that are anticipating implementing Voice over IP in their network, those that are in the process of piloting Voice over IP or even those that are in the midst of a VoIP implementation would benefit from this title.
The book is best suited for Project Managers, management, telecommunication and Data networking personnel. Really and truly, most anyone would benefit from reading this title. It covers such a broad range of information that having a well educated project team is going to ensure that the project goes smoothly and all things are considered. This book does an excellent job of presenting all of the issues that personnel involved in a Voice over IP project should be aware of to ensure success. It gives the reader a great appreciation for the complexities and helps a great deal with ironing out a good sound strategy.
This book has several figures, tables and diagrams. Like the old saying goes, "A picture is worth a thousand words". This statement holds true in the title. Like I always say, pictures are good.
The book covers everything you'd think about and everything you wouldn't think about.
Coming from the data side of a VoIP solution, I thought I had enough figured out to make a VoIP project a success. This titled made me think about issues that I would have otherwise over looked. Especially issues relating to traditional telecommunications.
Don't start you project without this book. It may end up costing you more than this book in mistakes if you don't.

Excellent book if you are looking for "in-depth" crash course in to VoIP. The amazing part was vendor neutral tone. Even though it came out of Cisco Press, it hardly preached any specific vendor. It was mostly focused on the fundamentals.

However the book lacks a decent index section. Hardly any important words are mentioned.

John Walker and Jeffrey Hicks's "Taking Charge of Your VoIP Project" (ISBN: 1587200929, Cisco Press) is an installment in Cisco's Network Business Series line of books and covers the topic of voice over IP (VoIP) from a business strategy perspective. Although the book does cover some technical aspects of VoIP, its main purpose is to guide the reader in understanding the steps from beginning to end on how to develop a business case all the way to deploying a successful and secure VoIP deployment. The book covers eight major areas:

* VoIP Basics
* Building a Business Case for VoIP
* Planning for VoIP
* Do It Yourself or Outsource?
* Quality of Service & Tuning
* Ongoing VoIP Management
* Establishing VoIP SLAs
* VoIP Security

This book's primary audience is meant to be at the managerial and above levels, although it does have value for senior technical staff, albeit from a different angle. For the management level, the book's value is in how it covers enough technical detail to make the reader aware of the complexities of VoIP, yet at the same time it presents both a business rationalization and realistic implementation steps so as not to scare the reader away (from the technology). For the senior technical staff or technical manager, the details of the technology will seem rudimentary, but the business framework may be less familiar territory, and therefore more valuable. For the technical audience, it addresses the often asked question of, "Where's the business need for VoIP?"

The eight categories can really be summed up into three major headings: VoIP Technology Summary, Business Justification, and Deployment Considerations. The "VoIP Basics" or technology summary provides the necessary background information on the PSTN and legacy PBX's in order to present the context for understanding how VoIP is a change in voice technology. This section is brief, and Walker and Hicks end with a general overview of data technology and how you converge old voice technology into it, discussing signaling, transport protocols, codecs, and the hardware necessary to make everything work. In terms of the business case for VoIP, the authors present three major cost savings opportunities: toll cost savings, simple network savings, and productivity savings. These areas are commonly talked about and should not be a surprise to the reader; the value here is that the book enables the reader to talk intelligently about the cost savings areas to a business audience. From here, Walker and Hicks cover how to project the ROI, how to make sure you have the data to back up your projections, and what associated costs should be considered before starting the project (e.g., is it cheaper to outsource?). Lastly, the authors spend time discussing both the pre and post implementation requirements and implications of running VoIP, spending less time on the technical details and more time on the big picture of implementing such a technology: Considering the quality requirements (i.e., QoS), integrating VoIP into a network management structure, establishing SLAs with the customer, and securing the technology.

Overall, the book provides a good, but broad treatment of how to present a case for VoIP and then deploy it. The irony of the book is that the readers who can best utilize the information will probably be the ones that find the book a little boring. For example, experienced managers will take away the unique points of implementing VoIP and recognize how it can fit in a realistic way for their particular environment. On the flip side, the knowledgeable network technician will similarly be able to see the nuances of VoIP that the book presents and understand the implications for the existing network. To both audiences, the pre-existing experience and knowledge may cause them to find the book too basic, although the lessons learned will most likely be valuable to them. To the less experienced readers (technical or managerial), the book is a great starting point and will most likely engage them more, but without additional references or resources (e.g., basic project management skills, understanding business budgeting cycles, etc.), the information learned may be just enough to make them dangerous.

"Taking Charge of Your VoIP Project" is a great resource for its intended audience of decision makers and project managers. It is not necessarily meant for the technical person doing the implementing, although the information is beneficial as it ties the technical to the practical.
