Re: Anyone with DirecTV or Dish Network?
My folks have had Directv for about six years and have never plugged their receiver into a phone line. I never had a problem when didn't plug in, either, but I keep it plugged in now so that the onscreen caller ID will work. The main reason they want it plugged in is to make sure your PayPerView purchases get called in by the reciever and thus placed on your bill.
Speaking of phone lines, can you use second and third Directv receivers without plugging them into phone lines?
Help stamp out, eliminate, and do away with redundancy.
