The Programmable Voice Call Events for individual calls can now be retrieved using a new Call Events REST API. Previously individual call events were only available via the Twilio Console. Using the new REST API you can programmatically retrieve the event logs of a specific call for further analysis or to populate your own dashboard.
Call Events can be used to programmatically analyze the result of the call, errors related to webhooks, TwiML returned by your application, as well as DTMF or speech input provided at various points during the call.
Please visit the API documentation page to learn more about using the API, and to access code samples in different languages.
