Response appreciated : Survey on Telephone Number Structure

[HiroHOTTA <]

Dear Colleagues,

ENUM Trial Japan (ETJP) was established in September this year 
following one year's on-the-desk study. In the study so far, 
Japanese community that has interestes in ENUM, including the 
government, have come to know that the telephone numbering plan 
and the ENUM DNS delegation model are very related to each other.
()

With this background, I think a survey on the telephone numbering 
plan in each country/ecomony is useful. I proposed a survey in 
a ccTLD meeting held along with Carthage ICANN meeting last month 
and the proposal was agreed among them.

Here let me send you the questionnaire for survey of telephone 
number structure in each country/economy. Forgive me if you 
have already received this questionnaire. as this has already 
been sent to ccTLD community cctld-discuss@localhost. I'd 
appreciate your response, hopefully in 2 weeks.

I hope this survey gives all of us information about "what kind 
of numbering plans and ENUM delegation models are our options" 
to go forward with IP phone and ENUM.

Regards,
Hiro JPRS

<purpose of the survey>

From the viewpoint of DNS management and operation, Numbering Plan 
for telephony service very much affects the ENUM Tier model to take. 
In considering appropriate numbering rules for IP Telephony and 
ENUM, information sharing about the numbering plans for IP phones in 
each country/economy is useful to decide Telephone Numbering Plan 
appropriate for ENUM era and appropriate ENUM Tier structure.

To exchange the information, here I send you questionnaire. I'd 
appreciate it if you'd support this survey and respond me 
hotta@localhost in 2 weeks. Responds are collected and put into 
a survey report and I'll send the report back to you.
