Assuming op is using an iPhone? I was looking into this for a friend and found something a couple of tutorials for making it happen with iphone, but they all said you had to use the interface from a computer (desktop/laptop) - that the call filtering and time block feature was not accessible via the phone's interface. (this was about a year ago?) - you could make your phone go silent, but let a selected set of contact be able to ring, or perhaps give another set of contacts the option to turn off your silent mode if they coded twice within 5 minutes or something? I think there is built in methods for this with do not disturb and assorted options with that feature on newish android without third party apps right? (I currently frequently use a "timed silent profile" app that I paid the premium for years ago, but I think I ran into these settings on base android in the past year.
