# Latency Report

<Badge icon="arrow-left" color="gray">[Back to Reports List](/ai-for-service/analytics/contact-center/reports/reports-list)</Badge>

The Latency Report highlights calls exceeding a defined latency threshold. For example, supervisors can generate a report of all calls where the P90 end-to-end latency is greater than 500 milliseconds (ms).

<Note>
  This is a beta feature. To generate Latency reports, enable capturing latency metrics by configuring these call control parameters:

  `notifySttLatency = true`

  `vadEnable = true`

  `vadVendor = silero`
</Note>

***

## Generating the Report

1. On the Reports tab, select **New Report**.

2. In the list of reports, select **Latency Report**.

3. Enter the **Report Name** and **Report Description**.

4. Select a **Time**.

5. Select **Data Filters**.

   | P90 Values               | Threshold Values (ms) |
   | ------------------------ | --------------------- |
   | `P90 End-to-End Latency` | For example, 200 ms   |
   | `P90 ASR Latency`        | For example, 200 ms   |
   | `P90 Bot Response Time`  | For example, 200 ms   |
   | `P90 TTS Latency`        | For example, 200 ms   |

   Each P90 value is evaluated using the following conditions: Greater than or equal to (`≥`), Less than or equal to (`≤`), Greater than (`>`), Less than (`<`), Equal to (`=`).

6. Select **Report Generation** and choose **Run On Demand** or **Schedule**, where you can create up to six schedules (only one for the Hourly option).

7. Select the Format (CSV).

8. Enter a **Send To** address (single email address or mailing list).

9. Select **Create** to generate the report.

10. Select the Run option to generate the report. Run On Demand generates the report immediately, while Schedule configures automatic generation at the specified date and time without manual execution.

11. Select the option to download the report.

<Note>The red dot beside the report indicates it was generated within the last 24 hours. You can download, save, and view the report in CSV format.</Note>

The report is available for download.
