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.
