I noticed you got  a call a few hours before I got one from that number.  It looks like a new spoofer is on the loose.  Since these calls are coming in on my business line, I now have my phone set to verbalize the numbers that are calling me and no longer answer them if I don't recognize them.  I notice they typically give up on my number within five tries although It may take a few days.  The more I don't answer them, the less calls I have been getting from anyone.  I only get one here and there now and the gap in between each one has widened.  My landline is attached to fax machine so now when people call that number they get a nice reception.  Suffice to say, those have stopped as well.  Remember, the more you answer them, the more calls you will get.
