I don't think I ever know the details of automatic TF routing, but I'm 
pretty sure that in California Zenith and Enterprise numbers were 
translated by R & R and sent collect.  Zenith 9000 is the only exception 
I know of.

Operator 25 (?) calls were just sent collect to the CB number.

In-WATS was purchased for particular areas (rest-of-the-state, for 
example) and calls from a point not paid-for simply would not translate.
