Carlos, as long as you have confidence in all your carriers' willingness
to complete a call to a given destination at a given price, I think the
simplest strategy for you would be to generate a retail deck according
to the most granular prefix available for every destination among all
carriers in your LCR table. When two or more prefix/provider tuples are
of equal prefix length, choose the highest one, the lowest one, or
average them, or average them and then add a certain %.
It really just depends on how likely it is that a given carrier will not
actually complete a call and you'll have to fall back to a much more
expensive rate from the next-cheapest carrier.
