Mr Number, my call-screening app, flagged this number as a telemarketer. I picked it up, put it on mute, and there was no one on the other end. Then it hung up after 5 seconds. (If this was a real person, they would hear that the line stopped ringing and they would say hello.) I have no information about who or what called since I'm not going to listen to a robo-call and try to talk to a person only for them to hang up when I ask for their company name or have them lie to me about their company information.
