Called a ring master number that I only give to family, so it's a robo call. I didn't answer and added it to my auto block list. (I love my Panasonic phone that lets me do that!) They did not leave a message. I later dialed *67 to call them to see if it's a valid number and heard the standard "survey is no longer active" recording that is used by the scam cruise calls. I see from other reports that this number has been used for that purpose as well as for other scams.
