Preface
AsteriskNOW is an open-source software appliance from Digium: a customized

engine and tool kit), the AsteriskGUI, and all the other software needed for an
Asterisk telephony system.
This book discusses the installation and configuration of the AsteriskNOW
open-source PBX appliance distribution and is written in the form of a self-study
guide or a quick cookbook, to get you up and running with AsteriskNOW as fast
as possible.
