ENUM Trial Implementation: IetF asked itu to facilitate government approval of EnuM implementations Under agreed procedures between lAB and ITU-T RIPE NCC will ask TSB if country approves eNUm delegation request If yes, it proceeds If no or no answer from the country, it does not proceed (tsB objects) TSB does not itself evaluate requests in any way. RIPE NCC checks technical as spects of requests 3.
