Book Description
Internet telephony is the integration and convergence of voice and data networks, services, and applications. The rapidly developing technology can convert analog voice input to digital data, send it over available networked channels, and then convert it back to voice output. Traditional circuit-switching networks such as telephone lines can be used together with packet-switching networks such as the Internet, thereby merging communication modes such as email, voice mail, fax, pager, real-time human speech, and multimedia videoconferencing into a single integrated system. Because Internet telephony allows the interchangeable and seamless use of phones, computers, personal digital assistants, TV cables, wireless, and Web technology, myriad combinations become possible.The transformation of the Internet from a network application using phone lines to a general communications infrastructure through which voice is but one of many data types offered has a wide impact on applications, architectures, networks, economics, public policy, industry structures, regulation, and service providers. This book explores these and other issues, and considers future scenarios as Internet telephony continues to alter the communications landscape.Contributors David D.

Book Description
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.
