Delivering telephone service to the house is the telephone company's business. For a fee, the telephone company also runs lines and adds jacks inside, but you'll save money -- and get exactly what you want -- doing it yourself.
Telephone wiring is straightforward, but running cable so it is hidden takes time and effort. Before running and stapling cable, plan the entire run. Extra effort may save trouble and eliminate an eyesore.
For instance, running cable through a wall may mean you do not have to run it around a door. For easy and secure connections, buy telephone cable that has solid-core 24-gauge wire. Cheaper cables have stranded wires that are difficult to handle.

Use a stud finder to make sure the opening doesn't overlap a stud. Cut a hole into the drywall with a drywall saw. With plaster walls cut with a utility knife first, then use a jigsaw. Slip a low-voltage (LV) ring into the hole and tighten the screws to secure the ring to the drywall or plaster.
Drill a 1/2-inch hole into the wall near the floor directly below the opening you cut for the wall jack. Insert a bent piece of wire, snag the string (jiggle the string to help snag it), and pull a loop through the hole. Attach the phone cable to the string with tape and pull it up through the hole.
