Internet Telephony

This book explores issues posed by convergent voice and data networks, and considers future scenarios as Internet telephony continues to alter the communications landscape.

Commemorating the 25th anniversary of the Telecommunications Policy Research Conference (TPRC), this volume begins with a historical survey of a quarter-century of TPRC meetings as one measure of change in and research about the telecommunications industry. Additional papers reflecting the ongoing pace of change in technological, economic, and policy issues are organized around four topics: * economic analysis of local and international telephone policy; * media industry studies including video competition, guidelines for children's educational television, and the setting of AM stereo standards; * applications and policy regarding the Internet; and * comparative studies in telephone and satellite policy. Collectively, the contents of this volume assess key issues for scholars, policymakers, and practitioners. Research reported in this volume illustrates the continually expanding scope of scholarly concerns about the telecommunications and information industry and contributes to further policy research and analysis.

A communication engineer's guide to the IP call processing protocols which set up and tear down voice/data/video calls over the internet. Covers both US and european standards.

If you want to grasp the full length and breadth of the rapidly developing computer telephony field, this book is the place to start. Author Richard Grigonis thoroughly explains even the most abstruse ideas in a concise manner that is aimed at all kinds of readers -- students, business executives, telecom managers, call center supervisors or entrepreneurial developers. Each encyclopedia entry is both an adroit explanation of computer telephony technology and a buyer's guide-like discussion of real-world products based upon technology currently available for business and residential communications solutions. ;

Translates technical jargon into practical business communications solutions This book takes readers from traditional voice, fax, video, and data services delivered via separate platforms to a single, unified platform delivering all of these services seamlessly via the Internet. With its clear, jargon-free explanations, the author enables all readers to better understand and assess the growing number of voice over Internet protocol (VoIP) and unified communications (UC) products and services that are available for businesses. VoIP and Unified Communications is based on the author's careful review and synthesis of more than 7,000 pages of published standards as well as a broad range of datasheets, websites, white papers, and webinars. It begins with an introduction to IP technology and then covers such topics as: Packet transmission and switching VoIP signaling and call processing How VoIP and UC are defining the future Interconnections with global services Network management for VoIP and UC This book features a complete chapter dedicated to cost analyses and payback calculations, enabling readers to accurately determine the short- and long-term financial impact of migrating to various VoIP and UC products and services. There's also a chapter detailing major IP systems hardware and software. Throughout the book, diagrams illustrate how various VoIP and UC components and systems work. In addition, the author highlights potential problems and threats to UC services, steering readers away from common pitfalls. Concise and to the point, this text enables readers—from novices to experienced engineers and technical managers—to understand how VoIP and UC really work so that everyone can confidently deal with network engineers, data center gurus, and top management.

Since the publication of the first edition, the CTI world has changed significantly. Where it was once focused on the integration of voice systems with computers, the focus is now on IP-based voice, or converged networks and services. Today, the telcos are upgrading their systems from circuit-switched to IP-based packet-switched networks. Companies

The authors bring together all the diverse information network professionals and developers need to build IP-based multimedia and voice networks, including coverage on key technologies, protocols, standards, security, access, and more.
