Called today from (806)387-2360, called-Id said Bill Ellison.  I was expecting a call at that time and answered by mistake.  After my hello, there was a pause indicating a robocall, hung up.  I suspect it's a political call - generally you don't get a spam message from a number with a real name (I googled the # and found it associated with a "Bill Ellison".  Generally this means someone calling from their home # for a candidate or party.
