Just received call from this number. Let machine answer and a recorded man's voice is trying to sell "environmentally safe FDA approved septic cleaning system". Not sure what FDA has to do with septic and sewage systems. Cut off the call.
03/21/2017, 336-355-1569 : Called a couple of times today. My call blocker stopped the phone from ringing but my phone system retains the number in the call log. Caller ID said "UNKNOWN CALLER" for both calls. Political calls usually have an 800 (or some such type) of number so it probably wasn't political, but I wouldn't put it past them.
