From: http://voipandenum.blogspot.com/2005/04/austria-starts-with-enum-based-numbe...
Austria started in December 2004 as first country worldwide with the commercial deployment of ENUM. In this phase existing geographic, mobile, corporate and national-portable (nomadic) numbers could be registered.
The next step will be the opening of the ENUM-based number range +43 780. The Austrian Regulator RTR <http://www.rtr.at> announced today together with enum.at <http://www.enum.at> , the Austrian ENUM Registry,that the opening of the number range for service will take place on May 17th, 2005 at 12 pm. From this time subscribers may register individual numbers on a first-come-first-serve basis.
The ENUM-based number range was defined in the new numbering ordinance (KEM-V) issued 12.05.2004 and is intended for convergent services. The numbers in this range may be reached both from the public Internet and from the PSTN and are linked with the related ENUM domain. Calls from the PSTN are routed via SS7 to VoIP gateways enabled to query ENUM to find out the SIP or H.323 URIs of the destination. On the Internet the End-user may query ENUM directly or via a SIP proxy or gatekeeper to find the destination.
So what is the advantage of this ENUM-based number range?
Unlike "normal" E.164 numbers the usage of these numbers is not bound to the provision of a telephone service.
The number range is specifically targeted for communications service providers offering only VoIP and related real-time communication services to provide their customers easily and swiftly with globally reachable E.164 numbers to be reached from the PSTN and also with an ENUM domain. The only pre-condition is to provide their customers with a SIP or H323 URI. Some will like to hear this, some may not ;-)
The subscriber simply requests the delegation of an ENUM domain in this range via an accredited ENUM Registrar. This registration triggers automatically the number assignment, so no validation is required, one of the major draw-backs of ENUM registrations of already existing numbers.
On the other hand the end-user may control the associated ENUM domain and change the NAPTRs pointing to his VoIP service at any time, thus "porting" from one provider to another.
But the number range also offers benefits to the conventional telcos on the PSTN, because they may provide their own gateway to route these number ranges and keep the money from the calling user, because no cascading takes place and no terminating fees need to be paid out.
ENUM allows the global connectivity between customers of different providers without the need of bilateral agreements both on the Internet and also from the PSTN.
This service is the first to truly implement the horizonal layered model of the future, separating transport, call set-up and applications. These open possibilities will enable an abundance of new and innovative services and applications for the end-users.

True, but such rules wouldn't be there nonetheless for the first time - and for sure not for the last time either... Whatever the rationale behind such action might be.

Porting the E.164 number in the PSTN world from one operator to the next, as the latter has much better break-out rates, for example. Or would that be entirely opaque to the subscriber as she deasls with a communication service provider only anyways? Thanks a lot - and best, -C.

Not necessarily. They need to cooperate with a communication service provider (KDB: Kommunikationsdienstebetreiber). All delegations within 0780 must name the KDB which will get the official allocation of the corresponding E.164 number.

The question misses the point. First of all, you cannot port numbers from other number ranges to the 0780 semantic. Or vice versa. Thus NP only applies within 0780. The call routing on the PSTN side is NOT AFFECTED by the selection of the KDB. Any telco can route *all* calls to *all* 0780 numbers to the same PSTN->VoIP gateway. The telco (KDB) currently owning the number has no right to receive the call via the usual SS7 interconnect. If there are multiple gateways available on the SS7 network, any telco originating calls to 0780 can choose the most convenient (i.e. cheapest) one to terminate calls to all 0780 numbers. All the business with the KDB "owning" the 0780 numbers has just two reasons: a) You need to provide a PSTN->VoIP gateway (directly or via a contract so someone else) before you're eligible to get 0780 number. => this guarantees that there is a gateway which all other telcos can use. b) The legal requirements on number allocations are fulfilled. /ol -- < Otmar Lendl (lendl@nic.at) | nic.at Systems Engineer >

thanks for the clarification - my former understanding came from Richard's original posting when he noted that "The subscriber simply requests the delegation of an ENUM domain in this range via an accredited ENUM Registrar."

That's clear.

[Thanks also to Alexander, who also clarified on that very point] After having slept over it (and some mind massages via private email exchange), I guess I need to rephrase the question appropriately: - What will be 780 termination costs like? - Is that being set by RTR, the Austrian regulator? - From what I understand what you (and Alexander) said - "If there are multiple gateways available on the SS7 network, [...]" - each TSP/CSP can pick any other gateway (true m:n relation), so eventually there likely will be a market price for gatewaying. - In the meantime, there might be only one or two TSPs/CSPs providing such gateways.

After having slept over it (and some mind massages via private email exchange), I guess I need to rephrase the question appropriately:
- What will be 780 termination costs like?
Termination costs as seen by the end-user, or termination costs between carriers?
- Is that being set by RTR, the Austrian regulator?
The RTR has specified only "quellnetztarifiert", meaning that the originating network is free to set a price they charge to someone calling a 0780 number. Based on hints appearing in www.telekom.at, I'd expect that to be somewhere between local and national tariffs for TA customers. Generally speaking, the RTR does not interfere in the pricing of carrier-carrier settlement regimes unless one of the parties complains. As far as we know, that has not happened yet, thus RTR is still out of the loop in terms of 0780 interconnection fees.
- From what I understand what you (and Alexander) said - "If there are multiple gateways available on the SS7 network, [...]" - each TSP/CSP can pick any other gateway (true m:n relation), so eventually there likely will be a market price for gatewaying.
Yes. If using someone else's gateway is too expensive, you can either build your own or route your traffic to someone charging less for termination.
- In the meantime, there might be only one or two TSPs/CSPs providing such gateways. Will they be regulated pricewise for the time being?
No. /ol -- < Otmar Lendl (lendl@nic.at) | nic.at Systems Engineer >

I wouldn't mind learning about both figures...

The possibility to complain of course comprise the user "party" as well, right? Thanks for your answers, -C.

Right now, I doubt that they have been decided on yet. On the interconnection side, I expect that carriers will start with the usual PSTN interconnection rates (not the mobile ones). On the end-user side, I guess the tariffs will be in the range of coorporate numbers and 0720 numbers. This might be slightly higher than local calls but will probably not exceed national calling. Not all carriers here still make a decision between local and national calls.

I'm not a laywer and don't know if consumers have a formal standing, but my guess here is that RTR will not intervene unless carriers use that number-range as a trap by charging outragious tariffs. That side is supposed to be solved by competition amoungst the telcos. IMHO if e.g. Telekom Austria overcharges here, than some of the alternative telcos will counter with special call-by-call or preselection offers which route calls to their gateway. As I see it, we'll have half-way decent prices for the first year, and if we will see decent uptake on the usage than deploying more gateways makes sense which then drives down the tariffs. IMHO that number range is very well suited for flat-rate style pricing as you don't have to pay other parties by the minute once you have your own gateway. We'll see. /ol -- < Otmar Lendl (lendl@nic.at) | nic.at Systems Engineer >
