Well, what I did is told the phone company I wanted a 2nd line for my teenage daughter (she doesn't exist) to be listed as Geraldine Katz (the name of my deceased cat) and then I now use the 1st line as a FAX line. In the rare event that I answer a persistant caller on Geraldine's line; I inform them that she's dead which usually aborts their script. I don't get a lot of other calls except for replies to the ones I initiate but that's what I wanted.
