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.
