Two phones, one appleid, calls noted on both phones: ?

You can still share with separate Apple IDs and Family Sharing. That's what Family Sharing was created for. Apple intends your Apple ID to be personal, and assumes that you control all of the devices sharing that Apple ID.

You can try turning on Facetime, then logging out of it (turning it off is not sufficient). If that doesn't stop the common call log the only other solution is to turn off iCloud Drive, but then you can no longer use it to share documents, which is one of your needs.

We have two (Verizon) iPhones. Neither has iMsg or Facetime enabled. Both are scrupulously maintained at iOS 9.3.4. One is the "primary owner" of the Verizon account. The other is a second line (different phone number) on the same Verizon account. Both use the same appleid.

When a call is made from or received on one phone, that call is logged on *both* phones. This is particularly annoying, and inappropriate for two unique phone numbers. All that Verizon agents have been able to suggest is disabling Facetime and iMsg on both iPhones. While this makes no sense, we've done it—to no avail.

Just in case, I thought I'd place the question here on the community forum. Ever hopeful.

Don't use the same apple id.

Great, glad it's resolved.
