The call events resource provides programmatic access to call progress and SDK events for a provided call SID. Call events are generated by call progress events and Voice SDK events. Events are typically available via the API within 90 seconds.
|Edge||carrier_edge, client_edge, sdk_edge, sip_edge|
If no Edge parameter is provided, the results will depend on the call type:

See Understanding Twilio Media Edges for more information.
Call events are represented by the following properties:
|account_sid||The account SID this call belongs to|
|call_sid||Call SID for the call the events are associated with|
|carrier_edge||Represents the connection between Twilio and our immediate carrier partners. The events here describe the call lifecycle as reported by Twilio's carrier media gateways.|
|client_edge||Represents the Twilio media gateway for Client calls. The events here describe the call lifecycle as reported by Twilio's Voice SDK media gateways.|
|edge||The edge reporting the event|
|sdk_edge||Represents the Voice SDK running locally in the browser or in the Android/iOS application. The events here are emitted by the Voice SDK in response to certain call progress events, network changes, or call quality conditions.|
|sip_edge||Represents the Twilio media gateway for SIP interface and SIP trunking calls. The events here describe the call lifecycle as reported by Twilio's public media gateways.|
NOTE: Voice Insights for mobile SDKs is supported for versions 3.x and later. Calls placed using 2.x mobile SDKs are not supported and details are provided as-is and may not be reliable indicators of actual behavior on the handset.
