idstatuscache.
This is the one that you're treating as a clue.
All you could say--
if this were the example, you could only
say that the person attempted to reach out
to 571-216-6374 through FaceTime audio on that date.
That's it.
If you wanted to say that the communication actually
established, you would go to the call logs for FaceTime.
If you wanted to say a message was sent,
you would go to sms.db.
So you're going to have to use this as a clue
and then go to the actual database or plist that's
going to store those artifacts.
