The deduplication policy allows correlating 2N/dual-stream recordings and keeping the better quality record only ( and optionally, deleting the other copy). To determine which copy/instance is better, either the voice quality check results (if available) or the number of RTP packets processed counter is used. The correlation of the records is based on the telephony platform call ID (which can be ambiguous) and the start - end time of the record.

Info

Deduplication does not remove any copy in case removes the worse copy by default, but no copies are removed if either the Keep the Worse Copy Too option is selected, or one of the following ambiguous situations occur:

  • The clock of the Recording Servers are out of sync, the start time of the two records differ more than 5 seconds.
  • The length of recorded media files differs for more than 3 seconds.
  • The RTP packet counters differ more than 200 RTP packets.
  • There is a mid-call failover at one of the recorders. This scenario leads to violating the first 3 requirements for the ongoing records involved in the failover.
  • For trading turret integrations, when one recorder starts later than the other leading to starting the recording of the ongoing calls later than the other. This scenario leads to violating the first 3 requirements for those records.

the deduplication policy will skip and never process again 2N records when the records are under legal hold and/or retention. The only exception is the case when the primary record should be kept and the primary record has legal hold and/or retention, the secondary record should be deleted and the secondary record does not have legal hold or retention applied.

If you want to execute a deduplication policy on a skipped record (due to legal hold and/or retention) you need to configure a new deduplication policy to do so.
