If you have UUCP source code, I have got a few subroutines that do just
that, determine accurately if a number is within your Local Calling Area
or even your Regional calling area. And they should be fairly (extremely)
easy to install. They are part of a ACU optimization package that
allows uucp to determine which dialout to use in order to minimize
costs. If you have several modems each on their own phone line with
their own message units, the code will round robin among them
until all message units are used up and then start using the cheapest
lines. I wrote this package for uucp in order to minimize netnews costs.
But then discovered it becomes obsolete if you place all your phone lines
under one billing number. Not a pleasant discovery, but the code is
still used since my uucp is now device entry rather than system entry
driven. I will post the code to the appropriate newsgroup (ie comp.sources)
if there is enough interest, otherwise I will arrange to send it direct
to you. THE ONLY Hitch is that you MUST have UUCP source in order to use
it.
