ENUM provisioning platform for 0.4.e164.arpa top level domain
by Adrian Georgescu 15 May '06

15 May '06

ANISP, the Romanian Internet Service Provider Association http:// www.anisp.ro representing more than 40 service providers (http:// www.anisp.ro/?c=membri) will build a provisioning system for the ENUM tree 0.4.e164.arpa. The Romanian ENUM exchange will be hosted in two RoNIX locations (Romanian Network for Internet eXchange) and will be backed up by an infrastructure hosted within the European backbone. The 0.4.e164.arpa is under the authority of the Romanian regulatory body ANRC, which by end of this year planned to define the final procedures of delegation and administration of the public ENUM tree 0.4.e164.arpa. A press release is available at: http://www.sipcenter.com/sip.nsf/newsview? open&type=News&docid=WEBB6PNKZT Adrian Georgescu AG Projects

This is wrong. ENUM is in production in other countries. A lot of SIP proxies query e164.arpa for all calls to E.164 numbers. That includes calls to countries where ENUM is not in production yet. Calls to Italy are thus running into a DNS timeout. This is not good. So please: Even if you are not in production with your country-code: PLEASE MAKE SURE THAT YOUR NAMESERVERS ANSWER. EVEN IF ALL THEY EVER SEND IS NXDOMAIN. Thank you. /ol -- < Otmar Lendl (lendl(a)nic.at) | nic.at Systems Engineer >

This will be apparent when the CRUE document is published on the new UK ENUM web site. [I'll make an announcement about that when it goes on- line.] The object of CRUE is to get lots of meaningful data into the UK ENUM tree so that ENUM-aware applications can be encouraged because there's a better chance of getting a successful ENUM lookup. The scheme is simple. Communications Service Providers register a block of numbers. This gets verified against the regulator's public database of block allocations to CSPs. The registry enters 2 NAPTRs for these numbers: a tel: URI and a sip: URI. The only "control" the CSP has here is the name of the SIP server: ie how non-PSTN calls can be terminated on their network. Now there's a lot of detail about ported numbers, allocation to end users and so forth. But that still doesn't make CRUE a replacement for "Infrastructure ENUM" whatever that happens to mean today. BTW I don't share your optimism that standardisation of Carrier ENUM can be completed this year. But let's not jump down that rat-hole. > I'm a bit concernced about diverging developments - maybe you can > enlighten us where you're heading and how this will interoperate > with the rest of us. CRUE is not a "standard". Or a protocol. It's just a means to get lots of NAPTRs populating the 4.4.e164.arpa name space. So there are no interoperability issues.

Niall, The TPAC will send their reports to the CC1 ENUM LLC. It will be up to the LLC to make those reports public. I suspect that since the LLC has an obligation to send those reports to all the CC1 North American Numbering Plan countries that they will be made public and accessible to everyone who is interested in the US trial's progress.

Carsten, My responses Q1: The number resources the FCC is meant to set aside for the ENUM trial - will they cover all US geographic area codes or is that somehow limited? If so, what will be the limits or restrictions? The US trial committee participants are identifying the geographic areas (NPAs) and the amount of numbers they require to conduct their ENUM test cases. Since the FCC has not responded to the wavier request with any restrictions or limits, there are none that I am aware of at this time. Trial participants do not expect to have limits placed on them beyond what the USG terms and conditions called for - that all numbers to be used in the US ENUM trial must be allocated under wavier by the FCC. Q2: In slide 5, 9 and 10 you mention the "Trial Participants Advisory Committee (TPAC)", what roles will be involved when in the trial and what documentation TPAC is meant to produce. I just wonder to what extent the users - aka. number holders, aka. ENUM domain name registrants - will be involved, as they seem to not be mentioned explicitly? The trial MOU calls for trial participants to identify what role or roles they intend to play in the US trial. The ones that I outlined in my presentation are the options that a trail participant can choose from. Such as number holders are identified as End Users and ENUM Domain Name Registrants once they have been authenticated and verified. There are several parties that have indicated that they intend to be End Users for the trial. Also the TPAC will produce reports on its trial activities on a monthly basis for the CC1 ENUM LLC. Initially these reports should contain the organizational plans (who is playing what role(s)) and test case development associated with the three phases of the trial. Once the trial starts, I expect that the monthly reports will contain the results of the tests that have been run during that month. Once the trial has ended, a final report that summarizes all activities and results will be complied for the LLC.
