  1. The Austrian ENUM Trialis closing down ETSI Workshop ENUM Febuary 24th, 2004 Richard STASTNY ÖFEG, Postbox 147, 1103-Vienna enum:+43 664 420 4100E-Mail: richard.stastny@oefeg.atrichard@stastny.com

  2. Why? • 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, numbering) (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 Richard Stastny

  3. Legal Framework • New Austrian Telecommunication Law (TKG 2003) • based on the 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 Richard Stastny

  4. Proposed Mandate AK-TK ENUM • Consultation of the NRA (RTR) regarding the policy framework • Definition of the technical and administrative processes between providers of ENUM-related services • Creating recommendations for the commercial deployment of ENUM in Austria • Open discussion platform for all ENUM-related topics • Monitoring the international developments, participate in international activities and exchange the experiences Richard Stastny

  5. ENUM Background in Austria 2000-09 Start of activities 2001-08 First consulation by Austrian regulator (RTR) 2001-09 Telekom Austria internal ENUM Task Force 2002-02 ENUM Workshop RTR, group of interested partners formed 2002-05 Interim procedures from ITU-T SG2 and TSB available Delegation request by RTR to RIPE and ITU-TSB 2002-06 Tier 1 Registry in operation by NIC.AT (the Austrian ccTLD) Delegations for 3.4.e164.arpa Start of development and deployment 2002-07 First draft of policy framework for MoU by RTR 2002-09 Austrian ENUM Trial Platform established (10 participants) 2002-11 Policy Framework and MoU ready, start Trial Phase 2003-10 Decision to start preparation for commercial deployment 2004-04 End of Trial, start deployment (planned) Richard Stastny

  6. Austrian ENUM Trials - Rollout 2002-03 Start of planning activities 2002-06 ENUM Tier 1 Registry (nic.at and Infonova) in operation Start of development 2002-09 ENUM Tier 2 Nameserver (Telekom Austria) in operation First clients available (ENUM queries on public Internet) 2002-10 Web-Portal for registration and modification in operation SIP and H.323 VoIP applications available First Live Demo in Atlanta, GA (VISIONng/VON/TIPHON) followed by various demos at ITU-T, IETF, VON and other workshops Set-up of Call Center and Registrar (Telekom Austria) 2002-11 ENUM Tier 1 Registry processes fully automated (nic.at) Test of provisioning processes with selected subscribers 2002-12 Ready to invite real ENUM subscribers and users 2003-02 Conversion to ETSI TS 102 172 compliance 2003-10 First part of trial completed, second phase started (business customers) 2003-12 Large Scale ENUM and VoIP Pilot started at the Uni Vienna (AT43) Richard Stastny

  7. Lessons learnt in the ENUM Trials • 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 (e-mail 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. Richard Stastny

  8. New approaches to ENUM • New approaches for IP Communications with ENUM: • ENUM for IP-based private networks ("PBX") with direct dial in • ENUM-only 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 Richard Stastny

  10. National Numbering Resources for VoIP • geographic numbers (fixed) • possible, but originations only from fixed line (for XDSL, VDSL), may use ENUM • also for IP Centrex and IP PBX with and without ENUM • numbers for networks (fixed and mobile) • yes, for IP Centrex and IP PBX with and without ENUM • mobile numbers • not yet, but ideal for ENUM opt-in (and later with 3GPP) • national portable numbers (fixed, mobile, personal) - 720 • yes, with and without ENUM, UPT services possible • numbers for convergent services (mobile, personal) - 780 • ENUM-only or ENUM-routed numbers, for virtual operators • 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 (see later) Richard Stastny

  11. Validation Methods • Identification: verification of identity of ENUM subscriber • (Re-)Validation: (re-)check the right to use the E.164 number • Initial Validation: for new delegation and for registrar change • Status Validation: check if ENUM subscriber still has the right to use E.164 • Validation method dependent of number range: • ENUM-only routed numbers (+43780) (infrastructure) • only identification required, validation implicit • Mobile numbers (opt-in) • identification and validation via SIM-Card (e.g. SMS) under investigation • numbers directly assigned to end-user (e.g. private networks) (opt-in) • identification and validation via assignment document • geographic numbers (opt-in) • identification and validation via credentials under investigation • If Registrar=TSP: Identification and Validation internal matter Richard Stastny

  12. ENUM as a glue • 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 Richard Stastny

  13. National Activities 2004 • Establish a national policy framework • Start commercial deployment of ENUM • Residential customers • ENUM-only routed number range +43780 • Mobile numbers (opt-in) • geographic numbers incl. +43720 (terminating on IP) • geographic numbers (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) • Generic Gateway and ENUM access codes • 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 Richard Stastny

  14. International Activities 2004 • Make existing ENUM Trials interoperable • ETSI ENUM Plugtest™ Workshop (February 24-25) • 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 Richard Stastny

  15. Primary Goals with some Examples • 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 • Corporate Users (Never touch the PSTN) • Call Flows • Broadband AT43 VoIP and ENUM Trial of the Uni Vienna • Linking IP PBX together globally • The generic gateway (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) • See presentation tomorrow Richard Stastny

  17. Large Scale IPC Trial at43 • Large Scale Trial on IP Communications using ENUM • University of Vienna ~100.000 Students • re-use of existing student account credentials via RADIUS • iptel.org SIP Express Router as SIP proxy with call routing, ENUM processing, PSTN interworking • some functions based on Asterisk open-source IP-PBX: • voice-mail, conference bridge, IVR, • PSTN Connection: CISCO 5300 PSTN/ISDN Gateway with PRA • Various Soft- and Hard-phones, WiFi-Phones, … • IP Connection to other universities, communities and "IP-PBX" • Applications: Crash test for VoIP, Chat, IM, Presence, SMS, use of SIM-Cards… • IP calls free, PSTN->IP calls by caller; IP->PSTN with call-by-call accounting • Naming, Numbering and Addressing with ENUM • Base: sip:<student-id>@sip.univie.ac.at • Austrian number for private networks: +43 59966 nnnnnn • global UPT number: +87810 2843 nnnnnn ORIGIN 6.6.9.9.5.3.4.e164.arpa. * NAPTR 100 10 "u" "E2U+sip" "!^\\+4359966(.*)$!sip:\\1@sip.univie.ac.at!" . Richard Stastny

  18. IP Communications global network • Phone numbers are now only routable over PSTN network • Connect “Friends and Family” Customers and Suppliers to the E.164 numbering plan using ENUM • and route this ENUM-enabled calls via the public Internet ENUM Richard Stastny

  19. The Generic Gateway from the PSTN • ENUM-only routed number ranges may be routed on the PSTN to a generic gateway • properly set up, such a gateway can handle several number ranges, e.g. +43 780 abcdef as well as +87810 abcdefghij • if the range can be determined in < 7 digits, any telco could use a GG anywhere and exit traffic early from the PSTN. • It is up to the PSTN operators to route any number in ENUM to these gateways (e.g access code or ACQ) • the gateway forwards the calls depending on NAPTR service contents • doable for SIP and H.323 in one gateway • iLEC‘s & LD operators will carry most of the PSTN traffic destined for these number ranges, • they are in excellent position to terminate these calls and grab the gateway business • Assumption: termination revenue > termination cost (IP & GG capex/opex) • with proper authentication and billing, the same gateway can also handle calls Internet-> PSTN with certified callerID Richard Stastny
