[enum-wg] Telephone numbers used in ENUM trial

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.
