Received an unsolicited call from this number which spoofed its origin (caller ID showed as coming from our company's operator, which I've confirmed was not the case). I answered "Hello", to which a real person on the other end spoke my first and last name. I responded with "Hello?" again, and the guy hung up about 3 seconds later. Had this happen before a few weeks ago from a different number.
This particular call's timestamp was 11:37:57am CST on 5/18/2015.
