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.

A comprehensive introduction to the protocols and architecture everyone must know in order to implement H.323-based IP telephonyIP 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:
