This is my first contract iPhone, and all day I've been getting these calls from Beaverton, Oregon. These calls were at 2:11 PM, 6:14 PM, and 8:52 PM. These calls are all coming from the same place, but they show up with different numbers. The phone will continuously ring until answered, and it will stay on the line as long as I'm quiet. But as soon as I say, "Hello." The call is disconnected. Is this a way of someone trying to steal personal information? Is that possible if a person is on the line long enough they have can get sensitive information about you?
