Duration
This field contains the duration in seconds for the record. For partial records, only the interval described by the
“recordOpeningTime” and the “last ChangeTime” in the “ListOfTrafficVolumes” is counted. The value is reset for each new
partial CDR. This value is converted from the internal representation in milliseconds to an integer value representing only
seconds. The mechanism for this conversion (ceiling, floor, round-off) can be configured.
