Who called from 3139890514

ID says only that its a michigan call

Caller ID says Big Net. They called yesterday, too. It didn't ring long enough for the answering machine to pick up.
Not a clue.

The same number also called a day earlier and ID'd itself on Caller ID as 'Prolife.'

Using a spoofed and invalid phone number, this is a recorded "robot" call, one that pretends to be a human, and waits for a pause before they continue on with their speech, so you think they're actually listening.   They are some pro-life organization (unidentified), and I hung up when I realized that there was no one actually listening.

Pro life organ.asking if I am pro life,against it or undecided.When I said undecided she hung up!
