I just received a call from the same number with no voicemail. While I have a license, I've never signed with any brokerage which would give some indication from where they're pulling their information.
3rd call today. picked up this last time and it had the usual 5 second no noise delay - then heard an audible beep on the other end and call ended. Tried calling back and received a fast busy tone.
I just flagged the number and wont answer it the next time. I am not sure what the point is maybe he is testing the numbers to see if they're good. But why call and not say anything or hang up. What a waste of time.
