I had this happen to me on my cell phone so I redirected the phone to a fax machine. The company was DocDepot in Charlotte NC www.thedocdepot.com +1 866-404-5835. They are a middleman between suppliers of medical equipment doctors and their patients. The faxes are patient orders for medical supplies.

I, too, receive calls from a fax machine to my home phone.  The calls come one after the other.  Thank you to Steve for giving some info on who the caller might be.  Theresa

We have received 8 calls within the past 30 minutes from this number attempting to  send a fax. We don't have a fax machine and the calls are ILLEGAL at this hour of the night and ANNOYING!!!!! STOP CALLING!!!!!!

We are receiving fax attempts from this number in the middle of the night, it is waking my husband and myself all night long. Please update your records to our correct fax #: 516-495-6690.

I keep getting multiple calls in the night from a fax machine. So frustrating

20 calls from this number in the last hour.  Stop calling my number now!!!
