Unplug the phone. Locate the exterior telephone service box, open the customer access door, and disconnect the telephone line.
Unscrew the existing jack, and ease it away from the wall. Unscrew the terminal screws, disconnect the wires, and set the jack aside.
Examine the wires. If the exposed portions appear damaged or brittle, snip them off, and use a wire stripper to remove several inches of the insulation. Bend each exposed wire into a "U" shape with pliers, and wrap the wires around the terminal screws on the back of the new jack. Tighten the screws.
Push the new jack into the wall, and screw it into place.
Reconnect the telephone line at the service box, and close the access panel. Plug in the phone, and pick up the receiver. The presence of a dial tone confirms that the new jack is functional.
