Have you “cut the cord” when it comes to your home phone? Many people have with the rise of cell phones!
If you no longer have use for your wall mounted phone jack, you have a couple of options.
You could patch it up by either cutting the wires and securing with electrical tape or disconnecting the wires altogether.
Other people have disguised them with cork board or art.
Family Handyman said, “You can use the space inside the jack as a mini secret safe. With the wires removed, you’ll have space to hide some cash, jewelry or small collectibles.”
