(240) 733-3557 is a Robocall

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

Great service, and I'm enjoying a good chunk of those 70,000 calls you block every day. The only improvement I can recommend is some way to mute the single ring that you're unable to stop. Guests sometimes ask why our phone rings only once, which does give us the opportunity to explain your service. Keep up the good work.

Really good

MOST EXCELLENT app. It truly works.

Mr. Foss,Thank you for a GREAT App. It is a stupendous success in my household. I just wish there was some way to track the real source of these calls so we don't have to play Whack-A-Mole every time the scammers just spoof another phone number.

Love it. But it also blocks calls that are dialed from a saved phone directory (my elder Dad does not remember my number but has it saved in his phone as a favorite). These calls are also blocked. Would like to be able to provide a list of numbers that are allowed regardless of how they are dialed.

I think it's the best thing since 'sliced bread'. My spouse and I look at each other and laugh when we hear that one ring. Another marketer left high and dry! A great help in this age of intrusion.

I was never able to install Nomorobo with my Comcast provider. I communicated with both your tech support, and Comcast's, but no one could give me a solution.
