This number along with other numbers call and say nothing, just hang up. When you call it back, all it says is "goodbye". Stop calling if you have nothing to say!!!
7/28 15:15 PDT Called just now. Don't know number but rolled to VM and after a brief pause, odd noise and some woman saying "hi, I'm Cindy. How are you today? then a brief wait and dead air when there is no response from my end.
