Trader voice recording has unique characteristics which require additional configuration when deploying a real time trader voice recording integration.
Voice Activity Detection (VAD) is an important feature of trader voice recording. VAD allows the recorder to detect voice activity and only record when a configured volume threshold (in decibels) is reached in the recorded audio.VAD is enabled by default for all trader voice recording integrations. It is not recommended to disable this feature, because certain call types, such as open lines, are continuously recorded while there is no continuous voice activity and the system would generate a lot of data (silence) unnecessarily.
Call Splitting is another important feature of trader voice recording.
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 |
|---|---|---|
| Minimum Voice Length (milliseconds) | The minimum length for a media record to be recorded by the service. | 80 |
| Maximum Silence Length (milliseconds) | Length of silence in media records before closing the record with voice inactivity. | 5000 |
| Volume Threshold (dB) | Sets the volume difference at which recording starts. | 40 |
| CDR Trigger Adjustment (milliseconds) | Defines the window of CDR matching used in Do Not Keep Openline CDRs Without VOX Activity. | 1500 |
Integration specific settings
The following settings can be configured separately for each trader voice recording integration. You can find these settings under Unified Call Recorder / Media Recorder / Media Processing / <INTEGRATION>.
| 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 |
