I think it may be a voip phone where the number shows up for different people. I got a call from a random person calling me, and based on when they called, I know why they called, and it couldn't have been a wrong number, unless it is a great coincidence.
This number came in on the caller ID with St Josephs Medical Center. The person then said they were security and that they had some of my property. They tried to get the last four of my SSN and verify my name. I called St Josephs and they said they had not tried to call and that this number did not belong to them.
