Ah, I see.

I have no idea how that would play out in general. In the case of the
numbers I call frequently, they rarely match longer than the 01234 stage.

Of course, in our problem domain the "client" is a local or even regional
switch or callserver. I'm not sure how well that approach would work.

There's also the question of how long you can assume the conclusion is
valid.
