I have recently purchased a "DVO-2" voicemail. The unit looks very simular to the vp412 (voice pro 412). It is a 4 line / 12 extention system. My guess is the it was the prototype before there was a vp412. I have been looking for the voltage input on this unit, as well a tip polarity. Or even better would be a manual? I have tried my transformer from my VP-206 (28 volt) but it did not power the unit up, someone said they thought it might need a 48 volt transformer, but I would hate to let the smoke out of the chips/caps as they dont work as well once you let the smoke out. Any help out there?
