Q: unanswered calls synchronising betweed different iPhones

it's by design the calls follow the appleID not the phones

same as apps and the likes

My recent calls appearing on another iPhone!?

Stop sharing Apple IDs

again.. stop sharing Apple IDs

Plus, it's a new feature...so that's why it hasn't worked the past few years...it didn't exist.

It's a feature that was added with iOS 8.3, so that's why it didn't happen in years past. And it only works when the affected devices are connected to the same WiFi network, so that's why it doesn't happen all the time. The idea is that if you are using your iPad or your Mac and a call comes in to your phone, you can answer it on the device you are currently using. See: Get help using Continuity with iOS 8 and OS X Yosemite. It also works for texts.

At the same time this feature was added, Apple created Family Sharing, so families no longer have to share the same Apple ID to share music and apps. Family Sharing - Apple Support

Hey guys,

I had the same problem and it was driving me crazy.

Until *drum roll* i unchecked the other phone no./apple ID from receiving the messages and FaceTime calls from the other IDevices and don't forget to check your laptops and desktops . now the call history has completely stopped synchronising. 

I hope this helps!!

this "feature" (as apple's friends call it) is very annoying, because you cannot share anymore icloud drive content with members of your family (with same appleid) otherwise you get same calls register (on normal phone calls)

apple probably now wants to limit number of people who can get free access to purchased apps by forcing them to use family share (that has maximum 6 free acesses)

poor steve jobs...
