I'm using an app on my iPhone called RoboKiller, and HOLY CRAP has it cut my spam calls to virtually nil. It's worth looking into for sure.
I tried that. But redirecting my phone number to a different service made me concerned.
Re: Ask HN: Why can’t I block all incoming calls that aren’t in my contact list?
#331How so? I mean, if you want to quit using it, you just delete the app.
