Blocking Numbers App

[OPTICS]

I'd like to request an app that keeps people, who are not on your contacts list, from calling you. Especially people who call with block numbers. The app wouldn't let the phone ring and would go straight to voice mail. I know for sure, a Razor phone has this feature.

Heres a thread I started about it.

Me too. I had it on my other phones?
