The concept is simple. It “watches” all calls coming into your phone provider and when it notices thousands originating from the same caller NoMoreRobo concludes it’s a robocall or telemarketer and the call is blocked.
It works with most voice over IP phones including Spectrum, Verizon Fios, AT&T, Vonage, and others.
If you have a Spectrum landline, it’s easy to activate. Just log onto your Spectrum account, click on “MyPhone”, and under settings click on “Peace & Quiet” - click on the “Nomorobo” section and enable the service.
Once it's all working (took me 2 minutes) your phone will ring just once everytime NoMoreRobo blocks a call.
