In that case, it makes perfectly sense to subdelegate enum, although perhaps it should just be a wildcard, so every number in the 12345678-domain goes to the same entrypoint just as a pstn-call does. Otherwise it could be confusing that when extension 10 changes physical sip-adress, you also have to remember to change the enum. Even more, enum-ing a number directly to a sip-phone sounds impractical. I know about blocks. When 3 major banks in Denmark joined in the end of last century, they got the block with being their main number, and the 'es for extensions.

One should generally assume that my posts are my opinion, which really doesn't need any more justification than I think so. If I have to start putting legal disclaimers at the bottom of my posts stating everything in this post is considered the opinion of the poster and should not be presumed to be the opinion of anyone else just to make sure that's understood, I'll be happy to do so, but it will be both silly and pointless. An ENUM number is a mapping of an E164 number to a service. If, in Austria, you 'own' all numbers that are your PSTN number plus any string of random digits, that's great... but it doesn't work that way in most of the rest of the world (I'd wager ALL of the rest of the world, but that's based again on supposition without accompanying hard data and spreadsheets and pie charts), and if the incumbent telecoms in the world thought people would use that methodology to cheat them out of money for additonal DIDs, they'd clamp down on it in a hurry. But regardless of how they do things in Austria, the fact remains that the original poster was asking a question about how to configure ENUM so that his phone extensions reached his correct targets. The suggestion by the registrar was only to register the main number. Suggestions by myself and some others were to register the main number and any other numbers. It was never stated that this was a limited subset country in which dialing codes are relaxed and non-standard, and so the information provided was, perhaps, not acceptable for the use case given the data provided. For making assumptions based on limited information, I apologise. But for thinking that such a dialing system is a distortion of the ENUM concept? I don't apologise one bit.

I'm not saying the people of Austria are hacking their phone system. That's an entirely different definition of the word 'hack.' And the application here is in terms of ENUM... which is an E164 mapping system. When you start playing fast and loose with the E164 numbering scheme (going above 15 digits, for example), I don't care how cool or useful it is, it's a violation of a standard. Standards are there for a reason... so people can create order from chaos. Adding in extra chaos just to satisfy one particular subset of people is still a bad idea. I don't care if the Austrian telecom advertises that everyone can make his own 16-digit number for the price of a can of cheez-whiz and a can of soup, the simple fact is ENUM is designed to map E164 numbers to services and a 16-digit number is NOT a valid E164 number. Doesn't matter if the entire country of Austria has one, it's still not valid as per the description of E164. You can say I'm being insensitive to Austrians or whatever you'd like, but that's not the case. I honestly think it's a neat idea what they've done with their numbering plan. But it's still a hack. And you can't violate a standard and then ask why your newly-devised rules don't work in situations applied to the standard. E164 - max 15 digits ENUM - E164 mapping as a UNIQUE identifier for services. 16-digit Austrian number != E164. Therefore, attempting to ascertain why a 16-digit number doesn't work well with ENUM should be a bit of a no-brainer. And with 11-15-digit numbers, you're still playing fast and loose with the concept of 'unique' in the whole unique identifier bit. When 20 numbers essentially map to the same thing, it's no longer unique. It's only unique-ish. Quote more from Austrian regulations. Please. It doesn't make their solution any less of a hack. It just makes it a widely-accepted and intentional hack. Again... it's a neat hack. It's a cool hack. But it's still a hack.

But the question was how to register them and if user X should create his own DNS server to handle the ENUM mappings. User X is free to do this, but then how is that server reached to map those numbers? There are certain 'accepted' ENUM registrars that have been IANA approved. User X could attempt to get his own approved, but even then, most existing ENUM tools would still not know of its existence, since it would be new. No! It's just like with any other name-to-IP resolution. If you operate your own server, you just have to tell your ISP to route DNS requests regarding *.YOURDOMAIN.TLD to your server. Any ISP should do this if you want. (At least, here in Austria every ISP does it) It's the same with e164.arpa requests. BTW, meantime I have alread implemented all that. My DNS server is up running. I've chosen one of the existing registrars and payed him for registering 7.6.5.4.3.2.1.1.3.4.e164.arpa as my number at nic.at. The registrar vaildated that this really is my number, and when this was confirmed, did the registration. Then I registerd my DNS server as the authorative master for the domain *.7.6.5.4.3.2.1.1.3.4.e164.arpa That's it. It works! When ever anyone anywhere in the world does a ENUMLOOKUP(mynumber), my server receives a request and (hopefully) sends the correct answer. Options are (as were provided) to register each of those numbers with an approved registrar (bulk registrations are often available), or in some way to convince a registrar to forward any and all requests to +4311234567[XX] to User X's DNS server. THAT might be tricky, but it creates a logical scenario in which there are 2 extra digits of a variable nature to pass off to the DNS server of the registrar and then forward to User X's DNS server. However, when you get into the idea of creating additional digits, it may become tricky simply because of the way DNS handles requests. No longer do you have a simple *.*.7.6.5.4.3.2.1.1.3.4.e164.arpa mapping zone, but you essentially need to create

Why shouldn't that be the idea behind enum? Norbert ENUM is, quite literally, E164 Number Mapping (that's what it stands for). If you're mapping numbers which are invalid E164 numbers (i.e. in your scenario in which you're taking an E164 number and attaching digits to it), you're violating the ENUM idea for the sake of convenience. You're also making the somewhat unfounded assumption that there will never be an actual number issued (to someone else) with those extra digits. Right NOW, there may be a convention that says that you can only have 10 digits in your country's phone numbers, but that could conceivably change at some future date, and then you'd be mapping numbers that belong to someone else to your own services. The only VALID way to assign ENUM numbers is to assign numbers you actually own. Not numbers you own with additional digits. Not numbers you own with extentions tacked on. Not numbers that are similar to ones you own. But ONLY ones you own. In this case, you own +4321234567, and only THAT number should be allowed to be registered as an ENUM number. Unless you, for instance, also own +4321234568 and +4321234569 or some such... at which time you would certainly be able to register those numbers and point them to your PBX. What you're suggesting, though, violates the ENUM standard... and should not be allowed.

But - at least here in Austria - it is definitely *no* assumption that my number with some extra digits can not be issued to someone else. The number +43-1-3207978 is my telephone number. I own it as long as I pay for it. And with extra digits behind it I can do whatever I like. I can create any extension - physical or virtual. I can attach a phone to extension 12, attach a virtual fax server for extension 12 to extension 99912 or could fire up my toaster if I call extension 911. I can invent any numbering scheme for my company. That's a fact! Again - At least here in Austria !! (can't speak for other countries) And why would nic.at (the owner of our .at TLD) offer the possibility to register a e164 domain specific Nameserver to answer subdomain-requests for your number if it would violate ENUM standards?

However, at e164.org, you can get a FREE164 number out of the +882 99 number pool. These numbers are for dialing Internet hosts only, they are not 'real' telephone numbers! There you can get a series like 88299 008971 0 to 88299 008971 for your extensions.
