Your first step into the world of IP telephony
Your first step to the world of IP telephony begins here!
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.
