How can I send all calls to voicemail during "busy" calendar events? Basically I'd like to have something that auto sends calls to voicemail when I'm "busy", and possibly as a bonus, send a reply text as well.

Is there any solution for this?
There are a few apps that can do this for you, or at least some of these things. One I saw on Lifehacker yesterday is Agent.


  Agent is a combination automation tool and personal assistant that will silence your phone during meetings, remember where you parked, auto-respond to texts and phone calls while you're driving, and more, all so you don't have to.
