I received a call from this number. I didn't SPRING to my phone to receive the call. I don't accept calls from unknown #s. In my industry, calls such as these are robo-calls. Predictive-dialers that call just to confirm that the number listed is valid. So, if you pick up, you would have confirmed your listed #. Thereafter, your # would be placed on a list of valid #s and so begins the telemarketing calls
