Most homes have single phone lines that end up in one or two phone sets. Single phone sets are commonly installed in most homes, but there are times when additional ones are needed. You may want to add more phones for convenience; unfortunately, the number of phones you can use in your home is limited by the number of telephone extension sockets or jacks installed in your home. Installing extension sockets inside your home is a simple task that can prevent you from being in such a desperate hurry to catch that call each time your phone rings.

Turn off power from the telephone company to avoid low-voltage shock. Telephone lines carry approximately 48 volts D.C. electric current, and an even higher voltage when it rings. Although both currents do not pose a danger of electrocution, they are still sufficient to give you a shock. Go outside your home, open the network interface device (NID) typically mounted on a wall and unplug the modular connector inside from its jack to disconnect power from the phone company.
Remove the faceplate of an existing wall jack closest to where you want to place the extension socket or jack, using a screwdriver. Look for the red and green terminal screws behind the faceplate, and loosen both screws using a screwdriver.
Get a telephone cable and strip off 3 inches from the tip of its outer sheathing to expose the inner wires, using diagonal pliers or utility knife. Segregate the red and green wires from the other wires, and strip off 3/4 inch from the tip of the plastic insulation on both wires, using a wire stripper.
Hook the red and green copper wires clockwise around the red and green terminal screws behind the faceplate of the RJ-14 wall jack. Twist the red and green screws clockwise using a screwdriver to tighten and secure the connections. Replace the faceplate to the phone outlet box on the wall.
Run the telephone cable along baseboards, walls or ceilings to the spot where you want to place the new jack, but avoid placing them closer than 12 inches from any electrical wire to avoid poor voice transmission. Use a stapler gun every 12 inches to fasten the cable onto surfaces. Cut the cable once it reaches its target location, but leave an extra 3 feet at its end.
Mount an RJ-14 phone jack (surface mount) on the wall nearest to where you will sit the new phone. Use the screws of mounting tape supplied with the jack. Loosen the red and green terminal screws inside the jack using a screwdriver.
Strip off 3 inches from the tip of the cable's outer sheathing to expose the inner wires, using diagonal pliers or utility knife. Segregate the red and green inner wires from the other wires, and strip off 3/4 inch from the tip of the plastic insulation on both wires using a wire stripper.
Hook the red and green copper wires clockwise around the red and green terminal screws on the RJ-14 wall jack. Twist the red and green screws clockwise using a screwdriver to tighten and secure the connections.
Plug a telephone set into the new wall jack. Go to the NID, open it and replug the short wire with modular connector inside into its jack to restore phone power. Lift the phone handset and listen for a dial tone.
