What you need for this book

Even though this book will provide you with step-by-step instructions, it is best if the reader has a basic understanding of Linux and its commands. For implementing Asterisk, you will need a PC with a P4 CPU or higher, 1 or 2 GB of RAM, and a hard drive of no less than 60 GB, 7200 RPM. Please note that it is possible to run Asterisk on lesser requirements; the configuration mentioned is simply a recommendation.
