Received a call from 630-225-6977 a little after 12 noon on 3/10/17; shown on CID as: "Warrenville IL".  We never answer calls from names, numbers, or companies that we don't recognize, so the call was picked up by our answering machine, but no message was left.  Quite obviously a spam/spoof/sales call of some sort, since legitimate callers leave a message and call back number; plus, the entire town of Warrenville IL wouldn't be calling!  Not sure WHY scammers think that people will answer calls that are identified as being made by an entire town???!  (I am marking this as a "prank call" in the Call Type box, since "scam" is not listed as one of the choices in the dropdown menu!).
