No, Kninjanin I do not, but it does not matter anyway because I have developed a system where I do not even answer the phone unless the call is pre-arranged anyway!
...and I have no long distance, just local calls...you can get by with all this if you are old and retired, and build your life around other centers of interest than digital...and as another layer of insulation, my caller ID lets me know if something has snuck in past all the other layers...
I end up with an unusual life, definitely out-of-the-loop of the rest of the world, but my life is my own!
