Hey, is there any way make it so that my iPhone does not disturb me with phone calls from unidentified callers? I often get calls from random telemarketers when I’m listening to music and it interrupts my listening experience. I want to make it so that, if the caller is not in my contacts, then my phone will not ring or stop my music (just like how it works when the phone is on “do not disturb” mode, then I can check the missed call or voicemail later if it is something important). Is this possible? How? Thanks.
