Here in PacBell territory calling line id won't start up
until October of 1991, but I'm already training myself to
*never* dial out on my private line.

I guess that is one of the ECM (electronic counter measures)
tactics that we're all going to have to learn when CLASS
features take effect.

Personally I'm looking forward to all the call screening
gadgets and software.  Finally, we techies will be able to
fight back!
