How do I wire up a Flash 4 voice mail system to the 8x24 stations? I want to use the full 4 simultaneous calls functionality. One tech has said it uses 2 station lines, another said, no, for full capacity, you must connect it to 4 station lines with 2 (qty) x 4-wire phone lines -- each phone line carrying 2 stations (1=red/green, 2=yellow/black on standard phone wire). Also, which station lines (of the 24)should be connected to the Flash 4 system? What programming needs to be done for the 8x24 to recognize the Flash 4 system?
