cool - so all registrars listed here: http://www.enum.at/index.php?id=64&L=9 would help me out?

Not necessarily, a registrar may not have the right to sell all number ranges; as I said before, a regisrar needs a contract with a CSP, see below

The definition of a communication service provider is different from a normal telco, and is also not restricted to Austrian company (This wiould not work anyway in the EU)

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.

I think there is a bit a misaunderstanding The registrar needs a contract with a CSP operating a gateway to guarantee that the 780 number range can be reached from the PSTN. This has nothing to do with the VoIP provider the subscriber chooses to point the NAPTR to.

- To what extend NP is implemented?

? What kind of NP do you mean?

Porting ENUM domains from one registrar to the other? -yes Porting ENUM doamins from one Name server to the other? -yes Pointing the NAPTR to another sip URI? -yes

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?

Again there seems to be a misunderstanding ENUM is only for incoming calls, the VoIP provider may not eben know that the user subscribing to 780 is pointing to him via ENUM

You may use this VoIP provider to make out calls, but you do not need to. An example: I chosae a registrar to subscribe for 780 and point the NAPTR to iptel.org and use a SNOM to receive calls. I also subscribe to sipgate.at, which terminates also a 720 number, which also terminates on the SNOM. For outgoing calls I use only the SNOM and for call to the US I use LibreTel. Of course normally is expected that your VOIP provider is also the registrar and also providing your outcalls. Normal user do not have any idea what ENUM is, so you will get it in a bundle Richard
