[enum-wg] market potential/future for public ENUM

Patrik is right.  It really is a competition issue. What I'm sure of is that
E.164 is NOT going away anytime soon despite what our IETF colleagues think.


The competition issue is also the driver for carrier ENUM as well.  I'm
getting serious hints on this side of the pond that the driver is HD Voice
(G.722) especially for the LTE mobile deployments rolling out in 2012. The
carriers finally realized they cant deploy anything new if the number
translation infrastructure remained the same.

The question is of course if the E.164 is to be used for other services than
voice. If so, without unbundling of E.164 from the (one) provider of
services, only the provider of the voice service that the E.164 is tied to
can also provide other services (like video conferencing, SIP etc).

It is completely up to the regulators what kind of competition and open
market they want.

for regulatory oversight of the Tier-1 delegation and name space: registry
contract, codes of conduct, SLAs, etc. If you were the regulator, what path
would you choose? :-)

I would immediately require the provider that is tied to the E.164 to

1. Run DNS/ENUM for the numbers they provide services for

2. Give the ability for the user of the E.164 to say what URIs the NAPTRs
for the E.164 should refer to

3. As alternative to 1+2, give the ability for the user of the E.164 to run
DNS themselves (directly or indirectly at a third party DNS provider)

4. Require the ones that run the LNP database (or equivalent) to expose the
content via ENUM

It is serious now. Either E.164 numbers will never again be used, and will
die a slow death, or it will be used also in the future. It is up to the
regulator.
