The card is in cabinet 2 originally in last slot, then moved to third from last slot.
I have 15 fax machines in the system. It seems to happen on 5 machines. These five machines get the heaviest in and out traffic. They could work fine for up approximately three weeks, then the extension dies. No dt and no receiving. Reset on port does nothing, moving that extension to any sl port will kill the port. The only fix is to asssign a new extension number to the port until it dies again. three dtmf receivers between three cabinets.C screen shows nothing off hook.
