This number and several numbers similar to it, calls everyday. They never leave a message and I don't know who these people are that constantly calls and hang up. I suspect it's a spam/scam call because it's like a robo-call trying to see if someone is available on the other end. This is har**sment and nothing is being done about it from the FCC Regulators. I've had this number for at least five years and I still get calls for the individual who had this number prior to me getting it. I wish they would go away but that's just wishful thinking.
