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.

Fax calls at 0730 when I have been up all night are not appreciated.

Fax machine. Called my cell phone 6 times in an 8-minute span starting at 7:27 EDT.
