A general statement: There seems to be a confusion with the terms telco and communication service provider For the avaoidance of doubt: To request an E.164 number in Austria you need to be a communication service provider according to the Austrian telecommunication law To be a telecommunication service provider no licence is necessary, the only requirement is to notify the regulator from the fact you are considering yourself a CSP. This is also complienat to the EU regulatory framework Richard ________________________________ Von: enum-wg-admin(a)ripe.net im Auftrag von Alexander Mayrhofer Gesendet: Mi 20.04.2005 12:55 An: chenhui(a)cnnic.cn Cc: lwc(a)roke.co.uk; lendl(a)nic.at; enum-wg(a)ripe.net Betreff: Re: [enum-wg] Austria starts with the ENUM-based number range chenhui(a)cnnic.cn wrote: > 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?

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.

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

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!

Hi all, I have several questions... 1) Which switching machine takes in charge of "triggering an ENUM query"? Is it the local-part machine? 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? 3) What is the charge module of ENUM application now? Is it based on number of services, just ENUM number, or some other things?

Hi Carsten, your questions: - subscribers must have [ ] Austrian citizenship [ ] Austrian residency [ X] neither one, ie. it's gobally open - registrars must [ ] have a certain license fo Telco operations [ ] be an Austrian company [ ] have at least an Austrian subsidiary From what I understand this is basically dealt with by the answer to the question who is eligible to become an enum.at registrar, correct? Correct, but non of the above applies The regstrar may either be a communication service provider, OR have a contract with a communication service provider 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) Since I have not the time to look up the related laws; so if you want to know more I reccommend to contact Robert Schischka from enum.at - 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 regards Richard ________________________________ Von: enum-wg-admin(a)ripe.net im Auftrag von Carsten Schiefner Gesendet: Mo 18.04.2005 19:19 An: enum-wg(a)ripe.net; enum(a)ietf.org Betreff: [enum-wg] Austria starts with the ENUM-based number range Richard, three short questions: - subscribers must have [ ] Austrian citizenship [ ] Austrian residency [ ] neither one, ie. it's gobally open - registrars must [ ] have a certain license fo Telco operations [ ] be an Austrian company [ ] have at least an Austrian subsidiary From what I understand this is basically dealt with by the answer to the question who is eligible to become an enum.at registrar, correct? - To what extend NP is implemented?

Austria starts with the ENUM-based number range
by Stastny Richard 19 Apr '05

19 Apr '05

From: http://voipandenum.blogspot.com/2005/04/austria-starts-with-enum-based-numb… 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. Richard see also: http://voipandenum.blogspot.com/2005/04/enum-and-skype.html

Hi Otmar, Carsten, folks, I may have been brushed by a bus, but the term interconnect worries me. Please use the LART if needed, but as I understood it... There is no NEED for an interconnect between an originating operator and any specific terminating provider. Any call to a 780 number MUST trigger an ENUM query, and the destination device is indicated by the NAPTR generated URL. This is done on the "originating side". Thus a PSTN originated call does not need to be delivered to another operator, so no interconnect is needed, only an ENUM-aware gateway. Of course, if the originating operator is too dumb to realise that this is "a license to print money" then they can make an agreement to deliver calls to any one of a number of folk who can gateway the PSTN call to a SIP phone. This is good news for those gateway providers, as THEY have the license to print money. Capitalism will ensure that they do not rob the poor originating operator for too much, but "the drinks are on them". In the longer term, the originating operators may set up their own gateways - there is a good business case, but it does require a clue. It is up to history to see if and how long this takes. all the best, Lawrence On 19 Apr 2005, at 13:11, Otmar Lendl wrote: > Hi, > > On 2005/04/19 13:04, Carsten Schiefner <enumvoipsip.cs(a)schiefner.de> > wrote: >> Otmar Lendl wrote: >> >>> The call routing on the PSTN side is NOT AFFECTED by the selection >>> of the KDB.

Hi Otmar/Richard et al. It's highly likely the majority of the people on this list don't understand German very well. The info at www.enum.at in English sees to be out of date: ther's nothing about the use of this new number range. Is there an estimate for when the web site will be updated? I hope I won't have to learn German to get a delegation under +43 780. :-)

Hi Jim, one requirement from the regulator was that the number range should be used "primarily" within Austria: One method to keep the Scots at a low level is to provide the registrar page only in German ;-) Richard PS: I think Othmar will give a more proper answer ;-) ________________________________ Von: enum-wg-admin(a)ripe.net im Auftrag von Jim Reid Gesendet: Mo 18.04.2005 22:45 An: Otmar Lendl; enum-wg(a)ripe.net Betreff: Re: [enum-wg] Austria starts with the ENUM-based number range Hi Otmar/Richard et al.

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
