A follow-up to Uyless Black's best-selling Voice Over IP, this book focuses on critical Internet call processing protocols -- giving professionals all the background they need to successfully implement voice, data, fax, and even videoconferencing across the Internet. In Internet Telephony: Call Processing Protocols, Uyless Black introduces each key IETF and ITU standard for Internet call processing, helping communications professionals resolve conflicts and achieve maximum interoperability. The book begins with a basic tutorial on telephony call processing and the differences between call processing on traditional circuit-switched telephone networks vs. packet-based networks such as the Internet. The book includes extensive coverage of the ITU H.323 standard for transmission of mixed-media signals such as videoconferencing sessions; the IETF/ITU Megaco Protocol for improving device interoperability and acoustic performance; and IETF's Session Initiation Protocol for IP teleconferencing. Black demonstrates how to build special services such as call waiting into IP networks; and an in-depth introduction into telephony traffic routing using the new Telephony Routing over IP (TRTP) protocol.

This book is one in a series of books called, "Advanced Communications Technologies." As the name of the book implies, the focus is on Internet telephony and protocols that support call processing. The book is an expansion of Advanced Features of the Internet, also part of this series.
The book has been written as a follow-up to the book in this series titled Voice Over IP (VOIP).
While the call processing protocols described in this book are oriented toward telephone calls, they also support calls associated with data and video connections. Examples of their support for all these applications are provided in several chapters.
I hope you find this book a valuable addition to your library.Notes to the Reader
There are four major IP-based Call Processing Protocols being deployed in the industry: H.323, SIP, MGCP, and Megaco. The chapters in this book that deal with other subjects are included because they deal with and support these four protocols.
There are many examples of protocol flows in this book that illustrate how the call processing messages are transported between the call processing nodes. I have prepared some of them, and others are sourced from the Internet RFCs, IETF working papers, and the ISO/ITU-T Recommendations.
These documents use different notations and figures to illustrate the flows. For continuity and to aid your study of these flows, I have modified some of them so that all are similar.
However, in some instances, I left the flows as they are described in the original specification if my potential alteration would have changed the interpretation of the specification in question. For example, some of the authors of the specifications use one "event" to show a message flow though multiple nodes; others describe an event for each instance of the flow at each node. I kept these practices intact; in the event you decide to study the actual specification along with the book, you will find both are consistent.
So, if you do detect some minor differences in my presentations of these important flows, they are there for this reason. Overall, you will find they are quite similar.From the Back Cover:
The key source for the principal Internet telephony services and standards.
The Internet now handles extensive video, teleconferencing, fax, and voice communications, in addition to basic data transfer. But overlapping standards for mixed media transmissions can confuse even the most sophisticated engineers. Experienced telecom leader Uyless Black brings together all the tools and protocols for call processing in this single authoritative source.
Internet Telephony begins with an overview of basic telephony call processing, focussing on the differences between traditional circuit switching and the more contemporary packet-based networks. A special section discusses telephony routing over IP. Along the way, Black explores the major standards and protocols in detail. Highlights include:
For engineers, managers, or users, Internet Telephony is the one book to cover all the technologies.
