Re: [Enum] IETF, ENUM and NGN



For my understanding, user ENUM consists of already existing telephone numbers already in use by end-users. Provider ENUM consists of blocks of numbers assigned to providers which in term get assigned to end-users.

These number ranges if PROPERLY delegated based on existing E164 numbering plans in place in each country do NOT overlap so they could stay in the same tree. Or do they?

how about not able to get a delegation needed in e164.arpa?

it is like saying we design this wonderful DNS system but no one is able to register anything under it.

What matters is the operators agree on a domain name for
Infrastructure ENUM. This might as well be e164.arpa since (a) it's
vendor neutral; (b) already an agreed IETF standard; (c) not
controlled by any nation. It's hard to see how any other choice of
domain name could be better (technically or politically). And it
prevents VoIP/SIP applications from getting schizophrenia from
figuring out which domain name they should use based on what network
they're running in today.
