Who called from 4044184651

comes up unavailable-  all telephone #'s should have an ID of the person or company.

Calls and when you answer they hang up.  Tried to call back.  No answer.  Called several times.

Same here called back several times and it just kept ringing

This is one of many numbers or spoofed numbers whose calls are intended for harrassment.  Whatever they pretend or don't bother to pretend the purpose is harrassment.

This number just called me but did leave a message.  "Hello?"  "Hello?"  It was a male voice, I called back, no one answered.  I don't know anyone in Georgia.
