The only response that works, to set up "do not disturb" at all times, is not good enough. This blocks all alerts as well.
The response to put your number on the "do not call list" is also useless. That is widely ignored. What we really need is to be able to block all _phone calls_ from anyone not in our contacts list, and have them go directly to voicemail. Apple: Can you _please_ provide this? If not, telephone service will eventually become completely useless.
You do realize doing that can be extremely dangerous and potentially illegal?
What happens if someone you do know calls you in an emergency from a number you don't have in contacts because its an emergency and it was the only phone available?
What happens if that person then dies because you, having blocked all calls chose not to take the call and as such they could not get help because of you? You could be held responsible for that.
The reason no such feature exists, is because there is no way to guarantee with 100% certainty that call from an unknown number is at the same time from an unknown person and this can then bring about disastrous results with potentially legal consequences to not only you, but also the company, be it Apple, or the carrier that allowed this.
