Résumé

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.

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.

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 are important items 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
