I'm spending the majority of this week at the AstriCon 2009 Conference in Glendale, AZ
http://www.astricon.net/
We are excited about AstriCon's sixth year as the official conference for Asterisk, the world's leading open source PBX, telephony engine, and telephony applications toolkit. AstriCon's mission is to expand awareness and knowledge of Asterisk over the course of a three-day conference and exhibition. AstriCon includes a wealth of information for every Asterisk user, whether you are getting started or have already discovered the power of Asterisk.
