Welcome to the world of voice over IP

We use either a telephone or e-mail for much of our day-to-day communication. Today, these two worlds are merging, and companies can place phone calls over their existing data network infrastructures using a technology called voice over IP (VoIP).

No prior experience with VoIP technology is required

Voice over IP First-Step is anyone’s introduction to the world of VoIP networks. The concepts in this book are presented in plain language, so you don’t need in-depth background knowledge to comprehend the technologies covered. If you work with data networks, if you work with telephony networks, if you’re a home user interested in how VoIP can reduce your monthly phone bill, or if the concept of VoIP simply intrigues you, this book is for you.
