I installed an expansion cabinet on a Magix today. I installed a 412 card in the first slot and a 016 card in the second. I performed a board renumber. The extensions for the 412 card came up fine but the 016 card did not, no system dial tone, and if I call the extension number it is busy. I checked the system boards and saw the 016 card in there. I did a print on the extension directory and I saw the appropriate extensions. Any ideas????
