Now we are at the point:
This basically how it is implemented in most countries running trials
(except France).
Historically, the whole issues started with the Report of the Department of State
ITAC-T Advisory Committee Study Group A Ad Hoc on ENUM (July 6th, 2001)
- Section 4.3 and 4.4 (Opt-in Principle)
which was the basis for the US ENUM Forum and taken over by ITU-T,
ETSI in their TS 102 051 "ENUM Adminstration in Europe" and finally implemented
in nearly all ENUM trials and implementations and not an issue for 3 years. As I said
in already in a previous post, the implementation in Austria is exactly along these lines.
Only recently, also with the re-emerging discussions on Carrier ENUM, the
opt-in principle is challenged again. A full attack to the opt-in principle was given
just two days ago from Tom Kershaw (VP on VoIP Services, Verisign) at the
ENUM Update Forum at the VON, stating "Opt-in must go or ENUM will never fly"
This is why I said iit is nteresting that bell-heads seem to act more according to
IETF principles then bell-heads ;-)

Betreff: Re: DUNDi
I guess it's time for my $0.02.
The interesting thing to me about DUNDi is the ability to "attract"
or "announce" numbers which I control and for which I would prefer the
calls to show up via some sort of VoIP call.
An example. Lets say I have a small business with an Asterisk PBX which
is connected to the PSTN. I'm also effectively attached to the internet
and make and receive VoIP calls (and probably do all my outbound long
distance that way).
Because I am paying the Telco for my PSTN lines, I would really prefer for
other VoIP users to just connect to my Asterisk PBX directly instead of
tying up my phone line. Plus, if I'm paying per-minute for VoIP LD
service, I would also prefer that other VoIP users also terminate directly
to my box.
There is a lot of discussion about how enum is going to be administered.
I have seen discussions that implies that enum is headed towards a
situation where the telcos which own the numbers will be in control of the
SIP records for that block. This seems problematic at best since the
telcos actually have a fiscal non-incentive to permit me to modify my
enum record.
The DUNDi system seems a little better in this regard since the
decentralized nature permits me to "announce" my telco numbers to the VoIP
world without involving the Telco. Of course, if enum is structured such
that I can change my records without involving the telco, that advantage
evaporates.
