Kerry Garrison has been in the IT industry for over 20 years with positions ranging from IT Director of a large multi-site distribution company to developing a large hosted web server platform for a major ISP, to finally running his own IT consulting business in Southern California. Kerry was introduced to the world of Asterisk by a friend and began running his own business on it. After about a year of working with it and writing some articles that became extremely popular on the net, he felt it was time to start putting clients onto Asterisk-based systems. Today, Asterisk PBX systems represent a significant portion of his business revenue. Kerry has spoken at Astricon and does a regular seminar series in California. He is also the publisher of both http://www.voipspeak.net and http://www.asterisktutorials.com. He is very active with the Asterisk and FreePBX community and has even contributed modules to the FreePBX project.
