Title: Stop! This is the worst tech book I have ever read.
Review: This book is not for tech people at all. If you want to learn Cisco's VoIP configuration, Cisco's web page is the best place to go. With this book, you will never know how to configure Cisco's VoIP. I bought this book and returned it right away after I took a look. Indeed, this is the worst network tech book I have ever read.I also want to remind the authors of this book: don't waste the readers' time!
Is the review positive or negative?
