Correct. I have checked with the ITU TSB. The following versions of H.225.0 are available: > Version Approbation > > 1.0 H.225.0 1996-11-11 > > 2.0 H.225.0 1998-02-06 > > 3.0 H.225.0 1999-09-30 > 3.1 H.225.0 Annex G 1999-05-27 > 3.2 H.225.0 Annex I 1998-09-25 > > 4.0 H.225.0 2000-11-17 > 4.1 H.225.0 (2000) Amend.1 2002-11-29 > > 5.0 H.225.0 2003-07-14 In version 2, type Progess-UUIE is defined as follows: > Progress-UUIE ::= SEQUENCE > { > protocolIdentifier ProtocolIdentifier, > destinationInfo EndpointType, > h245Address TransportAddress OPTIONAL, > callIdentifier CallIdentifier, > h245SecurityMode H245Security OPTIONAL, > ..., > tokens SEQUENCE OF ClearToken OPTIONAL, > > cryptoTokens SEQUENCE OF CryptoH323Token OPTIONAL, > fastStart SEQUENCE OF OCTET STRING OPTIONAL, > } But from version 3 onwards, it is defined as: >> Progress-UUIE ::= SEQUENCE >> { >> protocolIdentifier ProtocolIdentifier, >> destinationInfo EndpointType, >> h245Address TransportAddress OPTIONAL, >> callIdentifier CallIdentifier, >> h245SecurityMode H245Security OPTIONAL, >> tokens SEQUENCE OF ClearToken >> OPTIONAL, cryptoTokens >> SEQUENCE OF CryptoH323Token OPTIONAL, >> fastStart SEQUENCE OF OCTET STRING OPTIONAL, >> ..., >> multipleCalls BOOLEAN, >> maintainConnection BOOLEAN, >> fastConnectRefused NULL OPTIONAL >> } Ken, we are checking with the Rapporteur of ITU-T Rec.
