(301) 231-5100 is a Robocall

Fantastic! That single ring, while it initially makes you pay attention, its so nice to just have silence after that. I've recommended nomorobo to several friends, but they all have a phone service that doesn't use it.

I was a happy subscriber, but was very annoyed when I started missing calls from friends - they called, I heard 1 ring, and they got disconnected as I picked up. I did not realize that this was happening because of NOMOROBO, the the ISP techs (Time Warner RR) were here twice and it took them a few weeks to realize that it was the doing of NOMOROBO, I lost many calls, including bi\usiness calls during those at least 4 weeks, until I disconnected from your service. You should explain that this can happen, or better - fix this VERY annoying and serious problem with your otherwise welcome service.I might join and recommend you if you do that.

Simple, easy, and works really well.

Overall good service. Would be better if four-digit Caller ID numbers could be blocked. Would be much better if the phone didn't ring at all on a blocked caller, instead of allowing one ring.

You have no idea the amount of calls we used to get. The "do not call" list was a waste of time. Then I heard about Nomorobo. It has been outstanding. I counted 17 calls in a 5 day period. We get one ring, then nothing! Keep up the good work. ( it's a shame you can't get rid of the political calls) never met anyone who changed their vote after an annoying phone call.

I find it aborts calls after 4 rings but doesn't block them. I still get many unwanted calls.

Very effective. It brings me a small joy every time I hear the phone ring just once. I know Nomorobo just blocked another one! Thanks for a great service.

This is the best thing that has happened in our lives. Now there is peace and quiet and mostly calls from friends and family.
