The first chapter covers Internet Protocol version 6 (IPv6), and is followed by chapters that explain Resource Reservation Setup Protocol (RSVP), IP Multicasting, and Asynchronous Transfer Mode (ATM). Broadband packets are covered in chapter 6. The second part of the book covers codecs and evaluates offerings from a large number of suppliers in the VoIP industry. The CD-ROM that comes with the book contains product information from ABL, Telogy, and Nuera, including many white papers on VoIP technology.
This book will help anyone planning to implement telephone service using VoIP determine which technologies to use. Its clear style and intelligent use of graphics makes the material much more accessible than it would otherwise be. A good general understanding of telephony technology is recommended for readers of this book. --Robert Frankland
