My brother brought me a steel box today that he got free. From what I can figure via google, it's some sort of phone system. The box itself is about 3ft tall, 2ft wide and 2ft deep. On the outside it says "Mitel sx-200 Digital" Inside I can see 4 good sized computer boards with slots on them for finger cards. Unfortunately no finger cards. Anybody know anything about these? Any input is greatly appreciated. When I get a chance I could get a pic or two if wanted.
