# 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>
