That's not what he said. It may have been what he meant. Christian said "ENUM has nothing to do with assignment of E.164 numbers or national number plans". True, ENUM has no bearing on how E.164 numbers are assigned. Or how national numbering plans are administered.
That is what I wrote (with or without drugs. :-)) But
since entries under e164.arpa should correspond to assigned E.164 numbers according to the national numbering plan, ENUM does reflect how assignment of E.164 numbers are done.
No it doesn't. ENUM simply records E.164 numbers once assigned. it does not reflect the process of assignment. ENUM is not the expression
in the DNS of some random digit strings. Christian's remarks can be read as implying ENUM has no relationship to E.164 assignments or numbering plans.
I am talking very specifically about the authority behind assignment of E.164 and that is not through the ENUM tree but the E.164 national delegations.
Even so, ENUM does have something to do with national numbering plans. Obviously the registrations under <CC>.e164.arpa should correspond to the national numbering plan. For example in the UK context, it's not (yet) possible to register premium-rate and free phone numbers under 4.4.e164.arpa because authenticating them is too hard. These numbers live in ranges that have been set aside for those purposes in the national numbering plan. Similar problems could arise with DDI blocks, number ranges set aside for VoIP or DSL, etc etc. Thus ENUM is a representation of the national (and international) numbering plan. That's hardly "nothing to do with it".
see above. Christian
