(companies <> operators) (companies = ENUM user companies)

I know that there is infra-structure ENUM. My work will be on user
ENUM though. The infrastructure ENUM is here to stay, it is being used
on several countryies, companies and operators to route calls outside
the SS7 system. These are private ENUM trees, in fact, there isn't an
infrastructure worldwide/universal ENUM for operators. This may
happen, but I believe that there is no drive to it on the "old" PSTN
networks. On IMS, ENUM is part of the ecosystem. I wonder if there is
the "vision" to integrate the several ENUM trees.

I will be focused on user ENUM. For me this is the "hard" part of
ENUM. And if it is so hard, is it worth it? For me it is... the
Internet is user driven, ENUM may provide this shift of paradigm on
the Voice (and other) services. User ENUM will pushes governments,
regulators, operators and companies to the new paradigm. I think that
detach the e164 number from the PSTN Voice service is the first step.
The second will be to "force" operators to question the ENUM tree and
to terminate the call through their own gateways to the Internet, if
ENUM returns a valid address.

After that, the door is open. Once users get numbers detached from the
Voice Service, new services will be available, for sure. Users are
very innovative, and new users/usages will submerge. VoIP bases
services will be the frist (marketing, IVR, podcasts, ...), but others
will follow. Will it be cool to have a number to access your website,
I don't know... but why not.

What are the termination regimes available world wide?

Found some:
- bill and keep (US)
- cost based (access) (?)
- calling party pays (Europe)
