IPhone app to block callers at specific times? Is there an app or any other way on an iPhone 5 to block a given caller at specified times? 

Specifically, work keeps calling at all times of the day, every day. Is there a way to send their calls (and not everyone else's) to voicemail on evenings and weekends, but ring normally during working hours?
Do Not Disturb can do that, no 3rd party app needed.

You might have to juggle a new contacts group, because it only allows to receive calls from one group at a time, or favourites - so to exclude 'work' you might need to create a new group containing 'everyone else'



You can also toggle it manually from the Lock Screen
