Rather than LDAP, I'm thinking of taking advantage of the fact that we
have an internal 6-digit dial-plan.

So, if the dialed digits is _exactly_ 6 characters, prepend a #1,
which will then match the RasSrv::PermanentEndpoints

The documentation doesn't state if there's any sort of RegExp for RewriteE164?
I'm about to try this:

; Vidyo

But is that going to do what I want? I only want GnuGK to perform the
re-write if it's exactly 6 digits, and not if it's just part of a
longer dial-string.
