This payphone is a GTE-Quadrum phone with a Protel 310 board with both keys. You can use it as a regular phone or set it up as a payphone. It is in excellent condition and the enclosure has a light and phone book rest. I have tested it and it works fine. I also have all of the paperwork to program it. I will also consider selling the phone only.
