Re: [ASN.1] H.225 v4 - extenion in Progress-UUIE ?

[John Larmouth]

No doubt somebody will confirm, but I would point out that moving the extension 
marker means no interworking at all betweeen deployed version 2 systems and 
version 4 messages, if PER is being used.

The extension in Version 2 is specified after h245SecuityMode, however in version 4 (11/2002) the extension is specified after fastStart field, can someone help on confirming the following syntax in v4:

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
}

Thanks
