This 720-728-0047 number is in a series of spoofed fax numbers (about 200 in all) that routinely send junk faxes to our fax machines. 347-749-7415 is the number at the top of a spam fax we received from annexmed dot com. They were using spoofing software to send through number 720-728-0047. Any time they have to spoof the number, it's a scam.
