Got a call from this number claiming to be from AT&T from the fiber department and asked to speak to someone in IT department who manages telephone networks.  Told the caller I would need a name in order for me to transfer him over to anyone in IT department.  He then gave me a bunch of names that I cannot pull up in my system at all.  He probably just named a list he found over the internet to try and get lucky to be able to talk to someone to advertise his stuff.
