This number called my DNC listed landline (which also serves as our tiny company's fax #) today at 1404 hours and then at 1410 hours.  Both times, there was a fax beeping on the other end, trying to connect with a fax on my end.  I keep our fax machine turned off to prevent getting illegal spam faxes.  I'm glad I do because another site reported that their company kept receiving a 90 - 95 page "catalog" from the number, but what came through was a bunch of wingdings and other nonsense and the fax header said only "Fax."  I blocked my number and called the number that was displayed to see if it was some legitimate error but got a message saying the phone number is not in service.  Obviously, this is someone trying to illegally spam fax machines using a spoofed number or an overseas number that doesn't display fully on a caller ID.  Either way, I blocked the number so future calls will be automatically disconnected.
