I know where to find the official V&H coordinates, used to compute mileage
for long-distance calls to calculate their price.

I would like to know who calculates these, and more to the point, what
equations are used to set the V&H coordinates from the location of the
NNX, presumably expressed by longitude and latitude. How are the V&H
coordinates computed for calls spanning less than 40 miles?

Can anyone help? Can anyone suggest a source of information?
