Ken Fox from Recource Communications calls for a Manager, somehow he has their extension. The manager does not know them!

Exact same thing happened to me.  He called saying that "he had a conference call set up and Person X wasn't able to join.  He wants to get on Person X's calendar and was hoping that I could help"

Ken Fox calls and states that he's had trouble reaching me.  Not sure if I'm the person he needs to speak to, but perhaps I can direct him to the correct person if not.  Leaves no information regarding who he is or what he's calling about.  Irritating.  Caller ID says "Resource Commun".

Got the exact same message twice.

Me too, same message.  If you don't tell me why you're calling, I'm not going to call you back.
