Nope, it works on your phone line, not on the computer. If you make a telephone call and dial *70 before it, it disables call waiting. Pick up your phone, dial *70, then call a friend. While you're talking to them, call your home phone from a cell phone and see if it beeps in. You should get a busy signal when you dial your home phone since call waiting is disabled. If not, give Ma Bell a call and let them know. If you don't have call waiting as an option on your line, don't use *70. Hope this helps!
