My wife mutes her iPhone 5 at work because she has many landline phone meetings during the day and doesn't want the sound to play over her conference calls. The problem is that she often doesn't unmute the phone when leaving work. So, after leaving work, she will often miss calls or texts because she has muted the phone.
Is there any way to mute the phone on geographic location or time? Ideally it would just mute within a mile of the office and unmute otherwise. Alternatively, muting the phone 8-5 would work too, just as long as no action is needed to unmute.
