PLU has a digital telephone system, which means that the phones are different from the traditional phone you may be used to. No phone other than the one provided will operate in your room with the exception of South Hall bedrooms. Conversely, the phones at PLU will not work anywhere else. In fact, plugging one of these digital phones into a standard analog jack could destroy the phone's circuitry which operates at a much lower voltage. Because the phone is digital, devices such as answering machines and modems will not work from your room.
