Telephones used to need wiring, and they used to be fixed into place. Over half a decade ago, it became a status symbol to have more than one phone. They were still in fixed locations, but the wiring often extended far enough to be able to walk around a room. There are many older houses today where those ancient phone wires are still in place, and hiding unnecessary wires can be a challenge for those who do not want to remove them.
The advent of the cell phone was what took away the need for phones that were physically wired into homes. They made it possible to talk for hours on end without the need to remain in one room where the cord would stretch. Once they came down in price, millions chose them as an alternative method. Modern phone companies are now doing their best to cut out the entire wiring system for old-fashioned phones, and their wiring is often no longer charged with any service whatsoever. This includes a phone connection and the electricity used to make it work.
Phone jacks were the endpoints of the wires that brought voice into the home years ago, and they are small boxes that often sit on baseboards. These rectangular plastic boxes are connected where the phone wires come out of the wall, and they are often considered eyesores. For those who want to get rid of them, disconnection usually takes nothing more than a screwdriver and a few minutes. This leaves only the small wires hanging out of the wall.
Getting rid of old-fashioned phone wires can take a great deal of work. They can generally be severed where they entered the house, and the wires can be pushed into the wall. Sealing them with electrical tape might be best, and then they can be covered as if they never existed at all.
