Block telemarketers automatically in iOS

What I want even more at this point (and have told Apple as much) is a way to even prevent the phone from ringing. Yes, Airplane Mode and other hacks can do it but I want something better and OS-supported.

Maybe “making calls” was the killer app in 2007 when the iPhone was released but these days the idea of the ENTIRE DISPLAY being taken over at random is too much. I am almost certainly browsing the web or using some app and the timing is always terrible, shoving some unknown number in my face.

And yes, telemarketers are probably 95% of calls at this point. A huge number of people just text me or use something else. And even if you must call, leave a voice mail (which telemarketers never do).
