The folks at Fonality are starting a series of seminars about their new TrixBox offering a trixbox training and certification course for all trixbox community members. This is perfect for system integrators, & telephony professionals.
From what I hear the goal is to provide a training and certification course and teach how to successfully implement trixbox in a business setting.
The first of them are being held in Los Angeles at the LAX Westin Hotel on March 5th & 6th, 2007
