i didn't answer it.

This caller calls my place of work multiple times per day but no response upon answer. I suspect it's a spam call of some kind.

This number calls my work several times a week.  i answer, there is never anyone there and then it hangs up.  I just tried calling it back and there is music and says "all representatives are busy, please stay on the line".  I'm not wasting my dime or time on that.

This number called my business phone five times within less than two hours today and left a very loud beeping recording that just goes on and on. It is very disruptive as my business is a one room school, and the office is right next to the classroom.. When I tried calling it, a voice message just repeated over and over that all representatives were busy, and please stay on the line.
