Leif Madsen first took an interest in Asterisk while attempting to find a voice conferencing solution for him and his friends. After someone suggested trying Asterisk, the obsession began. Wanting to contribute and be involved with the community, and noticing the lack of Asterisk documentation, he co-founded the Asterisk Documentation Project.
Leif is currently working as a consultant, specializing in Asterisk clustering and call-centre integration. You can get more information at http://www.leifmadsen.com
