What Henning says below makes sense to me.

My understanding (and the use cases draft may need clarity on that) is that
the two facets are largely independent. In other words, you should be able
to run a TDM network with step switches and allocate numbers via an IP-based
process, even if you may have to use a dial-up modem to get your IP packets.
(As far as I know, the current US-specific number management and porting
process is based, in part, on Internet protocols, just a bit on the dated
side.)

 

I think suggestions on removing US-specific language are useful. As
discussed in this thread, I do see six broad challenges that apply, in
combinations in many jurisdictions:

 

(1) IP transition

(2) porting (either newly-introduced or with new capabilities, e.g., between
different modes or geographies), possibly with mechanisms other than
voice-based validation of porting intent

(3) automation for multiple levels of delegation, whether for PBX or some
IOT applications

(4) accountability of both holdership and "meta" data (CNAM)

(5) improved number utilization, with more "just-in-time" processes

(6) more flexibility in the number and structure of registrars/registries
(including, for small countries, outsourcing to third parties rather than
creating technology specific to Liechtenstein)

 

My sense is that the US is facing more of these challenges than many
countries at this point, but they don't seem US-specific. This is not new -
TV whitespaces and emergency caller location for wireless were initially
largely US problems, too.

Yes, but such a green field space can, and has been, implemented on the
PSTN, so the use of an all IP solution is  not a requirement.  Whereas your
draft implies that it is, unless I misunderstood something.
