A landline phone is a traditional phone system set up through phone wires. Most houses have landline access in multiple rooms, but if you want to add a line to a room that has no current phone jack, it is a simple process. For this task to work correctly, it is essential that you have phone service through a local landline provider.
Locate the phone wires coming out from the customer side of the Network Interface Device (NID) phone box located on the outside of your home. Use a screwdriver to open the box.
Find the phone wires connected to the box. Connect the fish tape to the red and green wires inside the box by twisting the ends of the wires together with pliers. Cover the connection with electrical tape to protect the wires from the elements.
Run the wires along the wall or ground to the inside of the house and into the room where you want to place the phone. Use the shortest distance possible to bring the wires inside the home. Drill a hole through the wall if you want to hide the wires. Thread the wires through the holes.
Attach the wires to the red and green wires inside the jack box with pliers. Screw the box into the wall. Connect the phone test line to the jack and then to a phone. Pick up the phone to see if you receive a dial tone. If you have landline service already, you should hear a dial tone. If you do not, then you will have to connect landline service to your NID box.
Go online to a landline service provider's website. You can also call the provider from a cell phone, or visit a physical location. Set up the landline service. The company may send a professional out to install the landline to ensure the service is received properly inside your home.
Retest the new phone jack. If it still does not work, then you may have the wiring attached in the wrong way. Check all wiring connections once more. When the wires are connected properly, you should hear a dial tone when you pick up the phone connected to that jack. However, some companies have to activate each jack themselves for them to work properly.
