Create a default 24/7 Schedule for Auto Attendants. Or if no schedule is selected or created then it is a 24/7 schedule.
Something would be better than trying to use the current system of changing the hours.
There is no way to determine if 12:00 am is the start of the day or 12:01 am. Because I selected 12:00 am, my initial schedule would not work.
Why is 12:00 am even permitted if it's not the start of the day?
