Overview
“Focused on why the reader should care about a particular technology, and what the reader can gain from it.” — Steven Shepard, author of Telecommunications Convergence, now in its Second Edition
IS INTERNET TELEPHONY FOR YOU? IF SO, HOW? ANSWERS HERE
With a potential 90 percent reduction in phone costs, voice over data networks could offer your business substantial benefits. But how do you know if telephone over IP (Internet Protocol) suits your needs and setup? And if it does, what will it take to make it work? If you want straightforward answers to these questions, you’ve come to the right place. Lighting the way to IP telephony is Ken Camp’s specialty, and in IP Telephony Demystified he offers the best set of tools out there for making basic get-going decisions.
You must read this book if—
* you’re on IT staff or in management of a small business and investigating voice over data lines
* escaping from the telephone companies’ clutches sounds appealing
* the economies of voice and data on the same network are obvious
* the no-go or go decision on IP telephony is your assignment
* what's-in-it-for-my-company questions are uppermost in your mind
* direct, measurable benefits is an important item in your agenda
* choosing the right protocol might be a job-saver
* before wrestling SIP, H.323, or Megaco/H.248, you want to know if the match is worth the prize
* practical how-to's on integrating voice into your LAN could reduce your workload
* you'd rather have quality-of-service (QoS) answers—on IntServ, Diff Serv, and MPLS—than quality-of-service concerns
* a 3D view of cost and service implications is what you seek
IP telephony is simply voice sent over an IP network like the Internet. It can mean enormous savings—but not for every business. This is the book that will clarify whether it's right for your company, and if so, how to make it work.

Editorials
From Barnes & Noble
The Barnes & Noble ReviewIn this book, Ken Camp starts out with a history and overview of telecommunications that puts the reader up to speed very quickly. Next, he engages in a useful discussion of Internet Protocol (IP) networking and the Internet, with a little history and a look at the protocols. A discussion of the transmission of voice in IP packets and telephony protocols gets to the meat of the subject. Then comes a brief look at the practical considerations of using IP telephony: traffic engineering, quality-of-service issues, and gateways between networks. Finally, premise-based telephony and network-based IP telephony services are discussed and evaluated, along with their future. The addition of an acronym and abbreviation list in Appendix A is outstanding.
IP telephony has potential for the future of business, but you'll need to understand the technology and the issues if you want to reap the benefits. Technology will continue to evolve: The key is to take advantage of IP telephony at the right time, and that time is now. This book will pave the way to that level of confidence and put you in the driver's seat! John Vacca
