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
*
whats-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-tos on integrating voice into your LAN could reduce your
workload
* youd 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 its right for your company, and if so, how to
make it work.
