Who called from 3303754001

It's Ohio, which is out of area for me.

We have had over 200 phone calls from this number.  It is attemtpting to fax on our home line.

I had also a series of 4 calls right in a row. When I would pick up - there would be no one there! I tried to call back several times, no answer...

my place of business has been receiving numerous calls from this number. i suspect it is a fax machine from a doctors office however I have no way of knowing for sure

It's Christmas.  Was not home.  Number was on caller id and it worried me as that is a hospital group.  (Worry that a friend or family member was admitted to hospital, of course.)  

I'm guessing that if people are hearing a fax machine sound, this is a matter of a worker trying to fax and dialing the wrong number.
