I also got this phone number on my caller id and no one answered.  I have select call rejection from my phone carrier and it works like a charm.  

Got a call from this number-caller I.d. said that it originated in Scottsbluff, Nebraska.  No message left on my answering service.  I'vehad calls from this area code before, usually overseas "trunk" calls to a relay station somewhere in western Nebraska...and is probably a SCAM!!
