I use it, it works great. Works on internet based phone service like Road Runner or Uverse. You set up your service using an alternate number answer. NOmorobo gives you the number to use in your set up. Your phone rings once nomorobo picks up rhe call and hangs up on it. Excellent.
Followed directions to nomorobo but it won’t take. Hmmmm. I keep trying. Darn.
