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.

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
