How to mute all phone calls during focus time
I am using iPhone 12 pro with IOS 17.
I want to mute all call (from contacts or unknown numbers) during focus time. I tried to do but I need to select contacts one by one. If I do this, still unknown call will not be muted.
All this can be managed through focus or automation.
Kindly advise the solution.
