Sweeper.log: Version [1.5.8.0]Primary key values empty in DT

[John Richard Procter]

This error means that the Recording Reference number, Date
and Time or the IP address of the Computer was not found
in the DT file.

If integration software is used(do not use SMDR data), all
the above mentioned data is populated by the integration
software. So if that doesn't fill in one of the required
fields, you can get this error.
