Used this line for a Dish Network DVR522 receiver and it works, except that after 2 or 3 rings, it disconnects, so my answering machine could never pick up. We have SBC DSL with filters on the line, so maybe it just isn't compatible through DSL, eventhough others have written comments and had no problems. Hooked up a regular phone line to my receiver and no problems. I never tried it using regular phone.
