(580) 225-3300 is a Robocall

Every time the phone rings once and stops, we smile and say, "Nomorobo!"

Works great!! After using it on my line I placed it on my 86 year old fathers phone and if the phone only rings once (which happens often) he knows its a telemarketer

I think it has helped, but quite a few numbers (including Gallup) get through with a single ring, which is less annoying than talking to them, but very annoying, nonetheless because these callers tend to call every day. I suspect this has something to do with the fact that I use Vonage SimulRing to call my home and cell at the same time, but I'm not sure. I've learned that reporting a problem has no effect (but, heck, you're offering a free service, so ...), which I why I didn't bother.Of course, the 2014 political campaign season was still unbearable, and I don't look forward to 2016, but I think your service is a great help, and I appreciate it.

It works at least 90% of the time. We get hammered daily by scammers who lie with their displayed Caller ID so this is heaven sent! It's not perfect, but nearly so and the best thing we've found.

I love it! I've adapted to ignoring the first ring. Only if it persists do I regard it as an incoming call and check caller ID. Thank you so much.

I and my wife just love it. It rings once and bam there gone. Only one minor problem. I'm getting calls from the same caller over and over again. This in minor to me because it still blocks them an only rings once. I can't thank you enough. We installed the app just before election time, and let me tell you it blocked a lot of calls. Great app. We can't wait for this to work on cell phones. I give it a 5 star +. Best regards Bill

One of the great joys of my day is hearing the phone ring once and knowing that Nomorobo has sent the unwanted seller (aren't they ALWAYS selling something?) on its merry way. Three cheers for this great idea.

Perfect answer to those annoying phone calls that come at the most inconvenient times! Interesting that since I have had this service for nearly a year the number of calls have dropped off over the pat few months. Robocallers must be getting the message!
