Received a call from this number. Answered the call bye saying "hello" and heard a couple of beeps. Then, the caller/machine hung up.

Girl called and asked for the owner by name.  When told he was not here she said no message she would call back later.

Didn't recognize caller. Didn't leave any message.

I suspect this is an auto-dialer. Calls the office several times a week with no one on the other end.

Called me in the evening. I didn't accept and they didn't leave a message. I called back with my caller ID turned off. Got a message that all operators are busy, and if I want to be added to do not call list push 1. I hung up and set my phone to auto reject. You should too.
