Some Observations

• Eager to do ENUM trial– Most have some sort of task force

• ENUM means different things to different people

• But have issues getting e164.arpa delegation– Operate under its own ccTLD

Followed up

• Agreed to form APETF – Asia Pacific ENUM Technical Forum

• Initial Members: CNNIC, TWNIC, JPRS, KRNIC, SGNIC/IDA

• Details will be available in June/July
