Who called from 2056508934

A robocall from unknown, did not leave message, but when you call the number back, all you get is a recording that says to leave a message. It has been noted to be a telemarketer. - A search shows this number to be from Alabaster, Alabama. A land line using DELTACOM, INC. - AL.

My caller id read Tuscaloosa, AL - same number.  Didn't answer.  There was just a dial tone when the machine picked up.
