Who called from 8609027319

It's a fax machine, redialing to send me a marketing fax and it's my business line/cell number.

This phone number has been calling repeatedly (5-6 times a day) for each of the last two days.  About 10 minutes apart.  When picking up it sounds like a fax machine.  When returning the number it immediately picks up to a fax machine.  How can I get off this call list?  It is infuriating.
