A FIGS Data provided by CAMEL Messages p. 12
GSM 02.33 lists the information that should be present in FIGS Data messages. Tables A.1 to A.3 show the information required by GSM 02.33 for call start and end and partial call records, and the CAMEL messages, if any, that provide this information. Note that partial call records are only available with FIGS Level 3.
The CAMEL message given for a particular call event, e.g. call end, will not necessarily arrive at that event. The FDS must have the ability to build up a full picture of a call as various CAMEL messages are received.

Dialed digits:
This always gives (for MO calls) the number originally entered by the party making the call, including any non-numeric characters.
Modified B/C party number:
As the number is modified by the gsmSCF itself, it is assumed that the FDS will have direct access to this field and need not scan outgoing messages from the gsmSCF to obtain the field. If, however, the FDS must scan outgoing messages, the field is given in field Destination Routing Address in message Connect.
Cell Global Identifier (CGI):
refers to the cell used by the MS at the start of the call.

The CAMEL message for SS invocation notification have not yet been defined so the call information for SS invocation notification can only be specified in general terms.
The notification of supplementary service (SS) invocation will be the same as Table A.3, except that information field "Type of Service" will be "Type of SS", and "Call Duration" will be "Time of SS invocation". "Type of SS" will be given in the invocation notification sent from the gsmSSF to the gsmSCF. "Time of SS invocation" will be the timestamp in the invocation notification or its time of arrival at the gsmSCF.
