Hi In H.450.3, call forwarding supplementary services, the response to interrogateDiversionQ.Invoke APDU is defined as follows IntResultList ::= SET SIZE (0..29) OF IntResult IntResult ::= SEQUENCE { servedUserNr EndpointAddress, basicService BasicService, procedure Procedure, divertedToAddress EndpointAddress, remoteEnabled BOOLEAN DEFAULT FALSE, extension CHOICE {extensionSeq ExtensionSeq, nonStandardData NonStandardParameter } OPTIONAL, ? } I would like to know, why the result has been kept a list of maximum 29 nodes. As far as my understanding goes, a list of 3 nodes would suffice, one node for each service type (CFU/CFB/CFNR). Ane help would be appreciated. Thanks Regards Vivek Jaiswal, Hughes Software Systems
