the idea is to notice differences, not similarities.  If the customer called
01234567890 and dials 012345679999 next, the client would have to probe (query
for NAPTR, feed into an ENUM lookup) starting with only 012345679, because
that's the first differing digit.  There is no conclusion drawn about the
length of 012345679*, because there are just too many options, at least in +49.
