beeping noise like fax machine!

persistent calls over and over again at 4:30 in the morning!...fax machine?

After receiving MANY phone calls from 425-427-7879 that sounded like fax machine, I called the number back.  I actually spoke to a very polite man who told me it was Costco.com  It is Costco.com's auto fax trying to fax confirmation of my order.  
I recieved another call, and just forwarded it to the fax machine.
The auto system faxed through what (it) wanted, and I did not receive any other calls!
Give it a try if you can!!!

I keep getting this call on my office line and it really is a distraction at this poiung
