Two phone numbers on FaceTime We have 2 iPads, 2 iPhones and 1 Apple ID. How can I add the 2nd iPhone number? Would like to have my iPad FaceTime &amp; messages associated with my iPhone; my husband's iPad FaceTime &amp; messages associated with his iPad.
1 Apple ID is the problem. 

You'd need to remove the ID as a contact source &amp; just use the phone numbers.

 Same settings for iPad, just laid out slightly differently
