(551) 233-5908 is a Robocall

Great Program!

it only works on some of calls its better but some calls still getting through

Love it when calls with no caller ID or other numbers I do not recognize simply "go away" without me touching the phone. Please, please, please get Verizon on board!

Best thing since sliced bread.

I wish it would not ring once when a robo call comes in. Can't the call be completely blocked instead?

Great! We love to hear the 'no-mo-robo' sound of one, single ring. It makes us smile all over. If a call is not a nomorobo call, we wait until just after the third ring, picking up the receiver just before the fourth ring. Any unwanted callers usually hang up before the fourth ring. Makes life much better.Love it. Have mentioned it to countless people. Some of them however, can't seem to get it due to their provider (Xfinity I believe.) Hope that changes in the future. Will try the Beta as soon as possible.EDC

This is a highly effective service. It has blocked so many calls to my home phone. At first I checked every call that didn't make it, worrying important calls might be blocked. Each and every time it was a spammer. I still have a few that get through once in a while. Is there any way I can report those to you for possible inclusion in your blocking service?Thank you so much for this invaluable tool, ... Dee

It's great so far! I was getting so many of those calls, particularly in the evening hours, and Nomorobo has helped to make my evenings more peaceful without constant interruption from unwanted calls!
