I got a call from this number, it was from the Letterman show ticket request I had sent in.

Yep. Letterman. We got free tickets. I love calls like this.

I WORK FOR CBS TELEVISION AND ALL THE LINES OUT HAVE THAT NUMBER AS A RETURN NUMBER.

I sent in a request for the David Letterman show tickets and they called back!  I got tickets!

I got a call back for tickets and the message was accidentally erased!  This number was on caller ID and it says out of service.

How can I get the phone number to call back!!!
