iPhone 6S Norway I'm looking to see if there's any way to give a caller an option to either reach me or go to voice mail by pressing a key. Example: I'm busy, but not too busy to not take really important calls. When someone calls me, they'd be greeted with a type of voice message "NAME is busy at the moment, but if it's important press 1 or press 2 to leave a message. Naturally I know of the Do not disturb and Emergency bypass option. Not what I mean. I'd like each caller to be given the option for this. Kinda like a switchboard I guess. Anyone know of a way?
