• Includes new coverage on the advances in signaling protocols, second-generation switching and the development of non-switched alternatives, and the implementation lessons learned.
• Contains in-depth coverage of network architectures used to support VoIP, performance and voice quality considerations, compression and integration methods for IP tranmissions.

Daniel and Emma Minoli--the authors of Delivering Voice over IP Networks--have written a book that begins by discussing all the issues involved in IP-based voice systems. The book discusses the IP protocol, Resource Reservation Setup Protocol (RSVP), Asynchronous Transfer Mode (ATM), and packet voice communication. Since many factors can influence the quality of voice data transmission, there are several mathematical models that can be used to evaluate such transmissions. The authors introduce and explain each model, weighing the pros and cons. Chapter 5 covers the technology and standards (G.728, G.729, G.729A, and G.723.1) for low-bit rate vocoding. The last two chapters focus explicitly on IP voice communications and the Internet.

Ideally suited for programmers, the highly technical nature of this book makes it appropriate for serious students of voice technology. Those in the computer field who need to know not just what technology is available, but also the inner workings of voice technology, will enjoy Delivering Voice over IP Networks. --Rob Frankland
