This book presents end-to-end system basics for IP telephony—the technology that enables private data networks to provide extended communication services and multimedia transmission over standard phone lines. Written by the chief architects of H.323, the governing protocol for IP telephony, this book delivers the most authoritative coverage of what is considered the hottest topic in networking today. Network and telecommunications professionals will find clear discussions of the principles and implementations of next generation architectures and services, as well as comprehensive coverage of the related protocols, addressing and routing issues, interworking IP with legacy systems, deploying gateways, and more. Mobility, security, and QoS aspects of H.323 systems are also explained in detail.

From the Back Cover
A comprehensive introduction to the protocols and architecture everyone must know in order to implement H.323-based IP telephony
IP Telephony with H.323
Internet Protocol (IP) telephony is changing the way business gets done, allowing multimedia messages such as voice, data, and video to be transmitted over standard routers, telephone switches, and lines. This authoritative book will help you gain a practical understanding of how IP telephony works by looking at the various protocols and architectural components using ITU-T?s H.323 standard. Written by the chief architects of H.323, it clearly describes the protocols that enable users to collaborate in a multimedia call as well as the H.323 protocols that permit supplementary services to be executed. The authors also explain the architecture and deployment scenarios of various types of gateways including network access gateways, trunking gateways, and residential gateways. In addition, they show you how security, QoS, and mobility can be integrated in H.323-based signaling protocols and the media streams.
Inside, you?ll find valuable insights on the use and implementation of the H.323 standard including how to:
- Utilize the signaling, control, and media protocols to initiate, communicate, and terminate a call
- Modify protocols to scale the size of conference calls to allow hundreds and thousands of participants
- Route a call and provide a mechanism for timing the length of the call
- Deploy Web-based protocols such as HTTP to control telephone calls
Integrate QoS and mobility in IP telephony systems

No more secrets and confusion about H.323!,
By Kaynam Hedayat (Chestnut Hill, MA United States) - See all my reviews
This review is from: IP Telephony with H.323: Architectures for Unified Networks and Integrated Services (Hardcover)
If you are confused about H.323 and are looking for a book that explains this intricate, convoluted standard, then you are looking at the right book. As an individual who has been involved with the standard from the early days I am very happy that there is finally a book that completely covers the standard in a language that is understood by everyone. This is a wonderful book.

Much Needed,
By Cheri (Aurora, Colorado United States) - See all my reviews
This review is from: IP Telephony with H.323: Architectures for Unified Networks and Integrated Services (Hardcover)
This is a treasure of H.323, VOIP information! Excellent protocol information. This is no paper weight, gathering dust! I use the book and I'm glad to have it on my shelf.
