cool - so all registrars listed here: http://www.enum.at/index.php?id=64&L=9 would help me out?
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.
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."
- To what extend NP is implemented?
First of all, you cannot port numbers from other number ranges to the 0780 semantic. Or vice versa. Thus NP only applies within 0780.
That's clear.
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.
[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. Will they be regulated pricewise for the time being? Best, -C.
