My mom's "new" house has one phone jack that isn't working. I'm hoping that it's just a problem with the wiring here at the jack (see picture below). It's basically one phone line that was cut in half and a jack was wired into place b/ the two ends. However, it's older wiring and I'm not sure about if the colors are matched up correctly or not. Can anybody tell or point me somewhere that might help? Thanks!
