Adding random digits to a PSTN and expecting to get the same person at a
different extension....  you don't think that's a hack? I do. One should
generally assume that my posts are my opinion, which really doesn't need
any more justification than "I think so."   If I have to start putting
legal disclaimers at the bottom of my posts stating "everything in this
post is considered the opinion of the poster and should not be presumed
to be the opinion of anyone else" just to make sure that's understood,
I'll be happy to do so, but it will be both silly and pointless.

An ENUM number is a mapping of an E164 number to a service. If, in
Austria, you 'own' all numbers that are your PSTN number plus any string
of random digits, that's great... but it doesn't work that way in most
of the rest of the world (I'd wager ALL of the rest of the world, but
that's based again on supposition without accompanying hard data and
spreadsheets and pie charts), and if the incumbent telecoms in the world
thought people would use that methodology to cheat them out of money for
additonal DIDs, they'd clamp down on it in a hurry.

But regardless of how they do things in Austria, the fact remains that
the original poster was asking a question about how to configure ENUM so
that his phone extensions reached his correct targets. The suggestion by
the registrar was only to register the main number. Suggestions by
myself and some others were to register the main number and any other
numbers. It was never stated that this was a limited subset country in
which dialing codes are relaxed and non-standard, and so the information
provided was, perhaps, not acceptable for the use case given the data
provided. For making assumptions based on limited information, I apologise.

But for thinking that such a dialing system is a distortion of the ENUM
concept? I don't apologise one bit.

And if you choose to go above 15 digits, you're violating not just ENUM,
but the E in ENUM, since an E164 number is limited to 15 digits.
