Asterisk 1.6 by David Merel

The book offers readers both a detailed description as well as step by step instructions on deploying software solutions as well as Asterisk configurations. Screenshots are provided in sections to give a visual perspective of the instructions. For Asterisk configurations actual sample code is listed in the book which can be directly inserted into your Asterisk solution. This book is aimed at anyone who is interested in building a powerful telephony system using the free and open source application, Asterisk, without spending many thousands of dollars buying a commercial and often less flexible system. This book is suitable for the novice and those new to Asterisk and telephony. Telephony or Linux experience will be helpful, but not required.
