I do not know who this was because it comes up as "Unavailable" on CallerID, but when they called me as soon as I picked up the phone, before I had a chance to say anything, they hung up the phone.
I got a call from a Tina at "Reliable Office" giving me a deal on buying paper. I have ordered from reliable from their catalog in the past. They say they don't have incoming lines, they have to call me back. I think I will call Reliable and check this out.
