This is behind the door in the bedroom. I got no idea why they did NOT just put another box in there. There are 3 outlets in the living room after all. So why this is there, I got not one clue. I assume it's wired into the box on the other side of the wall. I don't know how long it is as I don't want to wind it back up after checking. So strange to me. But it just may have been there for many years. Most of the people here don't actually have a land line - they just have a phone to let people in the building (they use it for the buzzer) and just have a cell. Even the old folks are getting rid of land lines. It makes me wonder why we needed a second aria code is most people do NOT have a land line. But this is life I guess.
