History So far….

Korean ENUM Forum (2001)ENUM 1st public trial service

Proof of concept : technical feasibility and availability of ENUM ENUM Demonstration in IETF (2003) from 13th. Oct. 2003 to 9th. Jan. 2004 ENUM trial registration(1300s), ENUM telephony(VoIP) useExamined ENUM potential and users’ interest

2nd extended trial service Throughout 2005More applications and interfaces (PC, PDA, IP Phone. Etc.) Drew not much attention from users and telcos

National Code(+82) delegated to NIDA (May. 2005)Discusstion of Infra ENUM introduction (2005~)

Consideration of VoIP Clearing House based on ENUM

Facts about Internet Telephony in Korea9 facility-based providers and 140 resellers Prefix (070) for Internet telephony Facility-based provider must have more 60 POIs to PSTN and mobile networkResellers need to have minimum 12 POIs to PSTN and 1 POI to mobile networkITSPs interconnect via Internet

Problems Too complicated Interconnection and billing systemOne ITSP needs multiple cooperations and systems to interconnectSmall companies must need to Interconnect facility-based companies and all calls should be routed to PSTN at leastITSPs run mobile NPDB and need trunk GW and other connection facilities

With ENUM-based VoIP Clearing House International interconnection based on IP can be easier System can be simplerENUM can be rolled as NPDB and no need to run NPDB among small ITSPs preparaton Internet telephony number portability

Issues

In 2006, focused on proof of concept and technical availability of Infra ENUM

Related document is being prepared

Needs more understanding of mechanism for clearing house : ESTI’s Open settlement Protocol and ITU’s H225 Annex G

Enters discussion among Ministry, ITSPs, vendors and related organizations

ENUM Trial' (Jan. 2006)Currently 2 organizations are participating

'Japan ENUM Trial‘ but Activities very limited ETJP (ENUM Trial Japan) & Interested individualhttp://etjp.jp

Interests in ENUM still remain, but there is no visible motivation from business aspectsETJP trying to reactivate its activity
