Voice Insights Overview

voice-insights-overview page anchor

Voice Insights provides call quality analytics and aggregation tools for investigating Twilio calls and conferences. Sensors in the Twilio Voice SDKs and on Twilio media gateways gather call metrics and events and send them to the Voice Insights platform for analysis and aggregation.

Once aggregated, these Call Insights and Conference Insights are made available through powerful reporting dashboards and detailed summaries in the Twilio Console to highlight aspects of call and conference behavior.

Voice Insights for Twilio Voice SDKs allows you to react to call quality events directly in your Twilio SDK code. For a reference of related Voice SDK events, please see Details: Voice Insights SDK Events.
