The Austrian ENUM Trial is closing down 59 th IETF Seoul, South Korea, March 3 rd, 2004 Richard STASTNY ÖFEG, Postbox 147, 1103-Vienna enum:

Richard Stastny 2  The Austrian ENUM TRIAL Platform has fulfilled its task:  demonstrated the feasibility of ENUM (proof of concept)  has its lessons learnt  solved the open issues (e.g. validation, numbers to use) (more or less ;-)  considers ENUM ready for production  so the trial phase is ending  For commercial deployment it is required  to create a legal framework and  to use an (existing) official platform (AK-TK)  (existing) Austrian Platform for technical co-ordination of public telecommunication networks and services  ENUM will be a Working Group within the AK-TK Why?

Richard Stastny 3  New Austrian Telecommunication Law (TKG 2003)  based on the New European Framework (NRF)  New Numbering Ordinance in Austria (in consultation)  taking ENUM already into account  Contract between NRA (RTR) and Tier 1 Registry (nic.at)  contains the policy framework for ENUM  the charter for the 3.4.e164.arpa domain  the validation guidelines for the Registrars  basic technical, operational and administrative requirements  additional technical recommendations from the AK-TK Legal Framework

Richard Stastny 4  Basic issues solved  ENUM technology works,  ENUM policy and administration: most problems solved,  but shift in focus for the business models.  The original business model of ENUM for residential subscribers with opt-in for existing numbers has problems:  it's a second line service,  privacy problems with multiple services ( spam)  Validation and re-validation problem, …  but the major problem is: How to overcome Metcalfe's Law?  The usefulness, or utility, of a network equals the square of the number of users  so new approaches are needed. Lessons learnt in the ENUM Trials

Richard Stastny 5  New approaches for IP Communications with ENUM:  ENUM for IP-based private networks ("PBX") with direct dial in  ENUM-only routed number ranges for IP Communications  mobile numbers with validation via the SIM-Card  and then the re-launch of the original ENUM model starting with teleworkers and road warriors to overcome Metcalfe's Law  Note well: IP Communications is not IP Telephony  it is IP based services  one of these services is VoIP - and others like:  Directory, Mobility,  Instant Messaging, Presence, Video, Chat, SMS, and, and, …  will become more and more important New approaches to ENUM

Richard Stastny 6  geographic numbers (fixed)  yes, with and without ENUM (opt-in)  also for IP Centrex and IP PBX with and without ENUM (opt-in)  numbers for networks (fixed and mobile) - 05xxxx  yes, for IP Centrex and IP PBX with and without ENUM (opt-in)  mobile numbers – 06xx  not yet, but ideal for ENUM (opt-in) (and later with 3GPP)  national portable numbers (fixed, mobile, personal)  yes, with and without ENUM (opt-in), UPT services possible  numbers for convergent services (mobile, personal)  ENUM-only or ENUM-routed numbers, for virtual service providers  a number is valid only if there is a corresponding ENUM domain and it can be routed only via ENUM  On the PSTN the number needs only to be routed to a generic ENUM-enabled gateway National Numbering Resources for VoIP

Richard Stastny 7  Identification of E.164 number assignees within the ENUM system  necessary for ENUM-only routed numbers (if prepaid is not allowed)  for other numbers depending on identification required for E.164 number  (Re-)Validation: (re-)check the right to use the E.164 number  this does not necessarily require identification within ENUM  Validation methods are therefore dependent on the number range used:  ENUM-only routed numbers (+43780) (infrastructure)  only identification may be required, validation implicit  Mobile numbers (opt-in)  validation via SIM-Card (e.g. SMS)  numbers directly assigned to end-user (e.g. private networks) (opt-in)  validation via assignment document  geographic numbers (opt-in)  validation via credentials under investigation  If Registrar=TSP: Identification and Validation internal matter Validation and Identification

Richard Stastny 8  Establish a national policy framework  Start commercial deployment of ENUM 2Q2004  Residential customers  ENUM-only routed number range  Mobile numbers (opt-in)  geographic numbers (terminating on IP) (opt-in)  geographic numbers primary line on PSTN (opt-in)  Corporate Customers (IP PBX and IP centrex)  geographic numbers incl. 05 (opt-in, IP PBX)  geographic numbers incl. 05 (ported out, IP Centrex)  Deploy Generic Gateway and ENUM access codes from PSTN  Enable numbers in ENUM for SMS and MMS  Provide trusted identification on SIP for CLI  Provide certificates for E.164 numbers  to be used in signaling and validation  Usage of SIM-Cards and IMSI for mobile IP Communications Austrian National Activities 2004

Richard Stastny 9  Make existing ENUM Implementations interoperable  ETSI ENUM Plugtest™ Workshop (February 24-25)  Update ETSI TS V2 Mid 2004  add sms:/ems:/mms:mailto and sms:/ems:/mms:sip  ETSI ENUM Plugtests™ planned December 2004 and February 2005  Advance RFC2916bis to draft standard (IETF)  Register various "enumservices" with IANA  Make "Interim Procedures" permanent (ITU-T, IAB, RIPE)  next ITU-T SG2 Plenary in May  Establish national policy frameworks  22 CC already delegated in e164.arpa, more to come soon  Start commercial deployment of ENUM  some countries are already planning commercial deployments of ENUM during this year International Activities 2004

Richard Stastny 10  An URI (AoR) entered in an ENUM domain related to an E.164 number allows you:  to reach any destination on IP from the PSTN/ISDN  ported out, ENUM-only routed numbers, access codes, ACQ  to reach any destination on IP directly from IP  by dialing the full E.164 number as default  dialing local numbers and cross connections is still possible if a proper numbering and dialing plan is used  see I-D: draft-stastny-enum-numbering-voip-00.txt  and to reach any destination existing only on the PSTN  but only calls to numbers not found in ENUM are routed via the PSTN ENUM as a glue

Richard Stastny 11  Primary goals of ENUM:  Goal 1: Never touch the PSTN, if you can avoid it  Goal 2: If you cannot avoid it:  a. early exit from the PSTN or  b. late entry to the PSTN  Goal 3: enable IP Communications (SMS, MMS, Presence, IM, Video, …)  Some examples:  Corporate Users (Never touch the PSTN)  Broadband AT43 VoIP and ENUM Trial of the Uni Vienna  Linking IP PBX together globally  Generic gateways (early exit from and late entry to the PSTN)  for all ENUM-only routed numbers and others  Infrastructure ENUM  The freenum.org trial (late entry to the PSTN) Primary Goals of ENUM
