Who called from 4195285503

they call my house but won't leave a message

I answered but no one was there. I set the phone down and waited 45 seconds before they hung up.

Left no msg.

This seems to be a "robo call"... I thought that the "do not call list" was supposed to block this type of call.

I answered this call today. It was a recorded message about legal action being taken against makers of certain birth control drugs.
