No message left. Tried to call back and it said I dialed the wrong number.

I had a call from this same number. Heard an automated voice but couldn't make out what it said. I also heard a mans voice in the background. Called back and it was an invalid number. People can use apps I've heard to change the number that pops up in your phone. Not sure if it is a prank call but strange it happened to me from this same number.
