After getting Asterisk running at home and finding the Asterisk@Home project to make doing installations even easier, Kerry began writing technical articles about using the system to run a business-grade phone system. After seeing the response to his talk about Asterisk@Home at Astricon in 2005, Kerry decided to write the first book about the system. Before the book went to print, the project was renamed to trixbox. After many rewrites to try to stay current, the first Trixbox Made Easy book was finally published with some additional help from Barry Dempster. Shortly after the first book was published, Fonality, the sponsor of the trixbox project, hired Kerry as the trixbox project manager to work alongside Andrew Gillis to keep the project moving forward, and he worked as the Community Director at Fonality until January of 2009. Today, Kerry is doing consulting work again, and working on his new project (http://pbxtutorials.com).

Credits to the family would not be complete without mentioning my dog Lola, who sat by my side during the entire writing of the book and provided a nice break whenever she needed to go for a walk. Andrew Gillis While not his intention to help create a revolution in the telephony market, Andrew's little basement project made it simple for millions of users to learn how to use these powerful tools. Tim Yardley Known to the world as "Engineer Tim", Tim worked on the trixbox CE project during 2008 as the build engineer. His contribution of information on how to secure a trixbox system was a huge contribution to this book.
