Re: [enum-wg] Austria starts with the ENUM-based number range
Axelm, For 1), Does it mean that in Austria, the session-control equipments (as you said, the several components, and maybe including softswitch?) in Telco network all support ENUM? For 2), Who possess(take charge in assigning) the 780 number range? Users should have a 780 number first and then have a corresponding domain,yes? For 3), I think the whole charge module can be refered to some aspects, not just registry. For example, different ENUM services(call/Voicemail/conference..) can have more charge module than '"per-delegation" based model'. BTW,what kinds of ENUM services have been provided in Austria except call? Best wishes! Chenhui

Hi all,
I have several questions... 1) Which switching machine takes in charge of "triggering an ENUM query"? Is it the local-part machine?
It will usually consist of several components: A SS7 "speaking" component, a ISDN to SIP/H.323 (talking about voice) Gateway, probably an external box doing the ENUM lookup and controlling the gateway, plus a session border controller / firewall ...
2) Is it that ENUM registry in Austria stores all the ENUM NAPTR records of all users? And telco service providers agree to cooperate with ENUM registry?
Neither. But:
It's the user's choice to opt in for ENUM (although the Telco is allowed to opt-in for the user as well). The NAPTRs are the user's choice, too. Validation can take place without an cooperating telco as well (eg. via providing paperwork, invoices, directory entries etc.)
However, with regards to the number range +43 780, a user is required to have the corresponding ENUM-Domain, because it's a prerequisite to number allocation.
3) What is the charge module of ENUM application now? Is it based on number of services, just ENUM number, or some other things?
If you're talking about the registry costs: it's a "per-delegation" based model - the registrar is esentially charged "<fee> x <number of domains>" with the fee slightly decreasing as the number of domains increases.

No, i didn't say that. I said that this would be a way to implement it. They would have to add such equipment to their network.

The assignment is done be the regulator via communication service providers. The 780 range is an exception from the usual ENUM procedure: For 780, you register the _domain_ first, and if you successfully aquire the domain, your CSP qualifies for the corresponding number assignment.
For 3), I think the whole charge module can be refered to some aspects, not just registry. For example, different ENUM services(call/Voicemail/conference..) can have more charge module than '"per-delegation" based model'.
Sure. But that is up to the service providers, which "package" the ENUM delegation together with eg. SIP service, fax box, voicemail, IM gatewaying.
BTW,what kinds of ENUM services have been provided in Austria except call?
We're investigating usage scenarios including SMS/text/IM, Fax, Video-SIP/UMTS and presence (that's us, the registry guys. I can't speak for the CSP community of course, i'm hoping they work on other topics, too). cheers axelm
