This number called me this morning. Given that the number appeared to be blatantly bogus, I chose to ignore it. It stopped after three rings with no message left.
This number also called me this morning 9:43 a.m., "NAME NOT FOUND," same as above, but did not read out an area code, just 024-5698. Since I'm in the city of Chicago, it's possible that it also could be 773. Again same as above, 3 rings and no message left on my answering machine. Probably some robocall system.
