This is a professional office. Everyone is trained to look closely at Caller ID for every incoming call. This one displayed "Out of Area" for the caller's name (or location) and 112089174447 as the phone number. Two strikes: (1) Not willing to identify themselves and (2) messing with the manner in which the number is displayed. We buzzed the call to voice mail. Caller hung up w/o leaving a message when voice mail began its greeting.
Same as everyone above... robo call. I called the number back and a message stated that "all operators are busy, press 1 to add to our 'do not call' list." I've pressed 1, but they keep calling back anyway, from random area codes.
Called the front desk at a busy office twice in a row. Recorded line, you can tell from the beep. No one ever on the other line, and they hang up after about 3 seconds.
