Trader voice recording has unique characteristics which require additional configuration when deploying a real time trader voice recording integration. These features allow a more efficient way of recording trader voice calls and potentially save on the cost of the infrastructure required for the deployment.

If the trader voice recording is configured with active-active (2N) fail over, and Deduplicate Recordings policy is required, absolute splitting is recommended. The relative splitting is based on the recording start, and it may create recording pairs that are not possible to match. |
VAD and call splitting also allow a useful feature called Do Not Keep Openline CDRs Without VOX Activity which means that the system will not create CDR-Only records for open lines when there was no media activity at all for a call segment. A call segment means a call that was split using the call splitting timer. Without this feature, the system creates CDR-Only records for open lines based on the call splitting timer configuration regardless if there was call activity or not. This can lead to creating a very large number of CDR-Only records in the system (because the open lines can be on for a very long time, see above) unnecessarily.
General settings
The following settings are applied to all integrations. You can find these settings under Unified Call Recorder / Media Recorder / Media Processing / Voice Activity Detection (VAD).
...
| Configuration Setting | Description | Default Value |
|---|---|---|
| Voice Activity Detection (VAD) Enabled | When enabled, the system will close the media records if silence is detected. | Yes |
| Media Inactivity Timeout for VAD (seconds) | Length of the timeout after the last RTP packet before closing a media record with voice inactivity. | 30 |
| Call Splitting Timer Type | Select the call splitting type. The following valid values apply:
The absolute timer defines the time elapsed from the hour, the relative timer is from the start of the call. | Absolute |
| Absolute Call Splitting Timer (minutes) | The time period for closing the CDR-Only + Media-Only records and creating new ones. Closed records become available for playback. VAD closed media records are available for playback from the Conversations \ Ongoing menu. | 15 |
| Do Not Split Records Shorter Than (seconds) | Minimum call length for call splitting. Must be less than the call splitting times configured at Unified Call Recorder \ Media Recorder \ Media Processing \ <INTEGRATION> \ | 300 |
| Relative Call Splitting Timer (seconds) | The time period for closing the CDR-Only + Media-Only records and creating new ones. Closed records become available for playback. VAD closed media records are available for playback from the Conversations \ Ongoing < menu. | 900 |
| Automatic Gain Control (AGC) Enabled | When enabled, the system will equalize the average volume. | No |
| Do Not Keep Openline CDRs Without VOX Activity | Discard the created CDR-Only record if there was no media activity.
| Only at call segmentation |
