Phone calls showing up on wife's phone
So when either my wife or I make a phone call, or receive/miss one, it is showing up on each others phones. If I call her iphone 6 and she doesn't answer, after I hang up it comes up as a missed call. Same things happen on her phone as well.
How do I stop this? Never had this until the last big update.
iPhone 6s, iOS 9.2.1
