A client who visited iTandCoffee last week had an interesting problem.
When her daughter calls her private iPhone using FaceTime, the call comes through on her work iPhone as well.
Why does this happen?
Was it caused by a Shared Apple ID?
My first reaction was to blame the use of a common Apple ID on both phones - in which case it would be understandable why both numbers would ring.
However, closer inspection proved that the work phone was set up with an entirely separate Apple ID. So this was definitely NOT the cause.
What causes this issue?
Having ruled out a shared Apple ID, we then looked at whether the work phone rang only when the daughter Facetimed, or always.
So, I Facetimed my client from my own iPhone - on which I had only her private number in her Contact Card. Only the private iPhone rang.
I then added her work number to the Contact Card and Facetimed her again.
Sure enough, both phones rang - all because the two numbers were stored in the one contact card at the caller's end.
I then added two unrelated mobile numbers to a brand new Contact Card. One was for an iPhone we use at iTandCoffee and for my husband's iPhone. They definitely don't share anything. When I Facetimed that new Contact (wanting to contact the iTandCoffee number), both iPhones rang again.
This is because Facetime is associated with the Contact Card, not with the individual mobile number.
If there are multiple iPhone numbers in a Contact Card - and if those iPhones have FaceTime enabled - then all of those iPhones will ring.
How to avoid this problem
It seems the only way to avoid this problem is for the caller to set up separate Contact Cards for the different mobile numbers.
Not ideal, I know - especially when the person on the receiving end is not in control of this, because it is all based on the setup of the caller's Contacts.
