I think this is the greatest, and what is good about it is it can distinguish between annoying calls and when my doctor's office calls on a recording that comes through. This was a genius of an idea.

Excellent service. Thanks a lot.

AWESOME!Best thing ever from Mount Sinai (like us)! Good luck with making it ever better, e.g. (pipedream?!) a code that I could enter on the phone to automatically report a robo caller to your database. GOOD JOB!

I see how it has blocked some unwanted calls. I'm totally satisfied!

Nomorobo works fantastic, I was getting 13 to 18 robocalls every day. Now we get 0, even blocks the annoying political call. I have recommended it to ALL my friends and family.Bobby

Has worked perfectly since installation. Only two calls in four weeks have gotten through nd I reported them for inclusion in the database. A great service to remove annoying phone calls and scammers.

I recommended it to a few relatives over Thanksgiving weekend. I am grateful to have Nomorobo to prevent so many annoying calls from coming thru! It took a while to get it installed on TWC, then another time period till I got any calls to screen. So glad I persevered with the help of Betty Lin-Fisher of Akron Beacon Journal. Some of my calls are stopped after 2 rings, rather than one - but that's great! I seldom get robo calls, but still report when I do. Thank you for coming up with this.

Its a great service, however it won't work on ATT land lines, I hope you can get that soon.
