Hi,

Lawrence Conroy pointed me out that my answer may not
be complete regarding your question and he added:

----

If one wants to register an ENUM domain associated with a telephone
number, and one's provider is not active in ENUM, then in most
countries (i.e. operating under most sets of eligibility rules) one
"has problems".
This is the common problem with ENUM - the Incumbent will not co-
operate (see Telia in .SE, BT in .UK, ...) so the customer has
trouble proving that he or she meets the eligibility criteria for
ENUM registration.

Eligibility is usually defined as proof that a person is provided
service via the telephone number associated with an ENUM domain.

So... IF there is a requirement to prove that a person has service
via a telephone number, then either their provider (who knows this
already) can confirm the fact easily and cheaply (i.e.
automatically), or other mechanisms must be used to try to show that
the telephone number is under the control of the person making the
ENUM registration request. These alternatives are often more
expensive and complex, and may well discourage individuals from
registering ENUM domains in the first place as these are cumbersome
or costly.
-----

I can only confirm the last statement, and this is one of the reasons
why the use of geographic numbers in Austria is preferred for
either to be used by enterprises (where the cost for validating
the pilot number is neglectible) or to be used by VoIP providers
porting the number to VoIP, doing the validation within
the porting process anyway.

The validation for mobile numbers is easier, because this can
be done in an automated way with sending in an SMS

For residential subscribers the use of ENUM-only numbers (0780)
is preferable, because here no separate number validation is required
(the ENUM delegation is the number assignment)

regards

Richard

The ENUM domain for the number in e614.arpa is belonging and under control 
of the
end-user. So the end-user is responsible for ALL entries in the domain, 
which
includes the VoIP service.

It is basically Bring-Your-Own VoIP provider (same as for e-mail)
The VoIP provider you choose needs not to participate in the ENUM
trial (or service) at all

Of course it makes sense to sell ENUM together with a VoIP account,
because normal users are not willing to get into complicated provisioning

Hi, O'Reilly, Girard,

Thank you for your guide.

I know your name, O'Reilly, through quite many presentations i've searched
in the Web. I feel glad to talk to you.

I now understand the using of numbering for ENUM trial.

However, the main point of my concern now is the services provided to ENUM
user when their providers do not participate the ENUM trial.
Sympathise with me if my technical knowledge is not relevant, as i'm quite
new.

How are services provided to ENUM registrant if their service provider from
which they obtain telephone number doesn't take part in the trial structure.
For example, i got a telephone number +050-xxx-xxx from my Japanese VoIP
provider, assuming that :). My service provider is not in ENUM trial
structure of Japan. When i bring this number to register ENUM record, how
the VoIP service be provided to me through ENUM. Or in that case, i can only
use other kind of services such as mail, fax, web with ENUM registration ?
Or through ENUM, other VoIP provider which offered service for the trial
will provide me service. I think it's not right when two defferent provider
provide same service for same number ?

Pls help me again. BTW, could you pls tell me what kind of services now are
offered in your ENUM trial.

Kindest regards,

Thu Thuy.

Hallo, Thu Thuy.

This depends on the relevant local practices and regulations.

In Ireland (+353), for the trial, any subscriber could approach a Tier-2
registrar and, subject to meeting the validation and eligibility
requirements,
have her number entered in the 3.5.3.e164.arpa DNS hierarchy.

I expect the production regime for +353 will be similar.

We had two Tier-2 registrars in the trial, each targeting a
not-very-narrowly
restricted subscriber group.  My university was one of these
registrars, and
considered "eligible" any member of the "University Community".  The
trial
was not so widely announced that we had to worry about the numbers.

For clarity, I should maybe add that UCD is not a telco.  8-)

Note that with subscriber opt-in, number ranges are relevant not at the
level
of allocation to telephone service operators, but only where the
subscriber
holds a block assignment, as in the case, for example, of a corporate
customer.

Try

dig 6.1.7.1.3.5.3.e164.arpa any

and bear in mind that this part of the +353 numbering plan has numbers
of the
form +353-1-xxx-xxxx.
