Hi folks,
There is really something very wierd going on. I took some time to dig into and found
the following info:
Really ... Gary Steve was there any SG2 input to this thing ... this is totally wierd that a ITU WG would propose a totally different numbering scheme here in conflict with E.164 principals.. .

Of course ,u initial reaction here was

A. this is H.323 ... as in , so what. OK I'm a SIP bigot ..

B. a X.500 like directory .. been there done that , a guaranteed loser.


ViDeNet (Video Developing Network) is setting up the so-called
"H.323 Global Dialling Scheme (GDS)".

This is currently a wild mixture
of a private numbering and dialing plan, containing of
1.an international access code '00', also called
THE WORLD GATEKEEPER PREFIX (very bombastic)
2.the E.164 Country code (the real one)
3. An organisational prefix?? (OP) -choose what you like e.g:
(Many national research organizations follow the telephone
number system in their country and use their area code and
organizational telephone exchange prefix. For instance, SURFnet's OP is 302305.
4.an Endpoint Number (EN)

This is all set up by a Numerical Addressing Space Management Team
Working Group (NASM) and implemented
in a ViDeNet Root Level Architecture set up with Gatekeepers.

At least ENUM and DNS is mentioned in the scope of NASM

NASM is responsible the management of ViDeNet numerical address space. This group designs the numerical address space and supporting routing schemes, including E.164int integration, hierarchical and flat structures, with particular emphasis on the root level and top tier architectures. Of particular importance is the alignment of existing h.323 addressing to E.164-like structures, in order to prepare the way for an eventual migration toward full DNS-based dialing, ENUM and related numerical address translation schemes.

Sofar ITU-T SG16:

At the same time SG13 is sending a liasion to SG2 AND SG16:
(TD122 (WP 1/2) Liasion on Videoconferencing Networks.
attached to SG13 Documents:
COM 13 - D353 (WP 2/13) - A proposal for launching research on videoconferencing services network
COM 13 - D356 (WP2/13) - Draft recommendation of a general description of videoconferencing services networks
both from China Telecom and Huawei Technologies.

In D356 a numbering plan is proposed (at least not containing an
World Gatekeeper Access code :-) and also not a choose as you like
Organizational Prefix, but instead an domestic access code.
(Regulators, watch out and free up some domestic numbering space,
to profide space for 100 Million H.323 Video terminals per country -
and the same for SIP). Hey, what about technology independance?
At least this proposal could be compatible with E.164

Both ideas are quite new, because neither a prefix nor an acces code can
be part of an E.164 number.

I attach below some excepts what I found sofar:

have fun

I consider this development at least very interesting in context with ENUM

curious but fundamentally irrelevant..IMHO
