Why are phone lines from same account receiving one another's calls?

Anyone have this happen, know why or how to fix it? We have 4 lines on 1 account. 3 lines recently upgraded to new Iphones. Since the upgrade, an incoming call to 1 line will also ring on one of our other lines. This is not messages or face time- phone calls only and not all the time. Any idea how to stop this?

If the two devices are iPhones then you are logged in under the same apple ID and need to disconnect one and create it it's own account.

If that doesn't work, let us know.
