Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
Carrier Grade Voice Over IP, 2nd Edition is an outstanding offering on Voice over Internet Protocol (VoIP). Chock-full of practical, down-to-earth essentials, this book puts a bounty of technical information and design considerations at the reader's disposal for immediate use. While it is indeed a scholarly effort, it is also easy to read, making it a good choice for anyone interested in the subject.

Daniel Collins begins with a helpful introduction to the subject and then dissects the various technology issues in the following chapters. Chapter 2 tackles a thorough discussion on various protocols and standards. Chapter 3 goes into speech and voice considerations. Chapter 4 provides an exemplary discussion of H.323, which allows dissimilar communication devices to communicate with each other by using a standardized communication protocol; and Chapter 5 is equally valuable in its presentation on Session Initiation Protocol (SIP). Softswitch architecture and media gateway control are reviewed in Chapter 6, while Chapter 7 goes into the signaling system 7 (SS7) protocol suite and network architecture. Quality of Service (QoS) is thoroughly examined in Chapter 8, and Chapter 9 furnishes the reader with design considerations for building and implementing a VoIP network. The addition of a glossary of acronyms is an extremely helpful feature.

If you are involved in telecommunications, particularly in tackling the future of carrier grade VoIP, this book will be an invaluable resource. It will help you generate the cutting-edge solutions needed to deploy a quality-based and competitive VoIP. John Vacca

John Vacca, the former computer security official (CSO) for NASA's space station program (Freedom), has written 38 books about advanced storage, computer security, and aerospace technology.

Offers solutions for a new application of the internet protocol (IP) that provides quality voice phone service alongside the internet and multimedia applications, with an emphasis on how networks can be made carrier-grade. Chapters address voice-coding techniques, the H.323 architecture and protocol suite, the session initiation protocol, media gateway control and softswitch, signaling schemes, and quality of service issues. The last two chapters discuss modem access and potential fax services. Annotation c. Book News, Inc., Portland, OR (

During that time he worked extensively with both wireline and wireless network technologies. He helped to develop and deploy 2G wireless systems in Europe; he played a major role in the adaptation of GSM standards for use in the United States; and he was a major contributor to the launch of some of the earliest PCS networks in North America.

Since leaving Ericsson, Daniel has worked for a new telecommunications carrier and, more recently as a consultant. In a consultancy capacity, he has provided wireless and VoIP engineering expertise to numerous network operators, consultancy companies and infrastructure vendors. Daniel's clients include PrimeCo Personal Communications (now part of Verizon Wireless), Synacom Technology, AT&T Wireless, Alcatel USA and several other companies.

Collins is co-author of 3G Wireless Networks, published by McGraw-Hill. He holds a degree in Electrical and Electronic engineering from the National University of Ireland.

    A Comprehensive Introduction to VOIP

    Daniel Collins has done a marvelous job of explaining VOIP. He starts off each major concept with basic 'high level' info and builds up the details as he goes through. His use of flow diagrams is very useful. There is no fluff, and very little repetition. The last chaper is very good - I wish other authors emulate it. I highly recommend the book. Some constructive feedback for the next edition: 1. If he could provide an overview of the softswitch architecture at the beginning - that way, we know what part he is tackling and what remains to be tackled, as we go thru the chapters. 2. He missed out on covering RFC 3263 (using DNS to locate SIP servers). It was a mystery to me how a SIP server in my domain would figure out the corresponding SIP server in another domain. 3. He drew up a very nice protocol hierachy for H.323, but not for SIP. So for example, I had to look at other sources to find out that SIP could work on UDP, TCP, TLS or SCTP among others. 4. Please add a chapter covering real world SIP/H.323 servers and their important features. No need to recommend one over the other - but it would be nice to see how real products work. 5. Please add a chapter/section on IP PBXs. Having said that, I still believe this to be a very useful, easy to read book.
