Called at 4:03PM. I don't answer calls from numbers I don't know and they didn't leave message.

Didn't answer, voip call, and no message left.  Called around 3:45

Call came in at 9PM from Norwood, NC.  Sounded like a black male.  He asked to speak to my wife.  I said no, don't call back, and I hung up..  He called right back from an unidentified number.  He said, "Ha.  It's me again.  Is she available now?"  I said, "No. What do you want with her?"  He said, "Okay.  I'll call back tomorrow." I find this threatening and I'd very much like to communicate with him FACE TO FACE.
