So I updated to public beta 2 today (I could go to DP6, but it was just easier to software update to PB2). When I try to place a call from my Mac, it just says "iPhone calls are not avail...." then "Your iPhone is not configu..." They're both signed in to the same iCloud account. I tried turning wifi off on the phone and it at least knew my iPhone wasn't on the same network. This is on a mid-2011 MBA but this feature should at least work. What am I missing?
