This number tried to call me 5 times in one minute. My phone provided blocked each attempt, because it suspected the number is a spam caller or scam caller. Must be one or both if tried to call so many times within one minute. Thanks to Comcast and their relatively new Robo blocker which keeps our phone from ringing when called by suspected spammers. Furthermore, caller ID showed that "name not available" which means caller has blocked their ID which to me is prima facie evidence of being up to no good spammer or scammer.
