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
