I am hoping that I am wrong about the single-ring "alert." I sometimes get 10 or 15 junk calls per day, and having each and every one ring my phone a single time would be a continued annoyance. If it's true, then I see no point in implementing Nomorobo and will continue to seek out a call-blocking service or method that really works.
"If a robocall is blocked, then your phone rings once."
Thank you for the info, KevinM2. That's a deal breaker, free though the software may be.
yeah i am having the same problem . I get calls all hours from either telemarketers or scammers. Why would we want our cell phone to ring even if it is only once. I'll get 7-10 calls a day sometimes. That is just as aggravating as the calls them selves? Why does norobo work ONLY if you provide another phone number like a cell? Flawed system. Yes the numbers should be blocked but we shouldn't have to have a different phone ring!
