Twilio Changelog

A deleted call recording can now be fetched via Programmable Voice API using a new IncludeSoftDeleted querystring boolean param and set its value to true when fetching a recording resource or reading multiple recording resources. By default, fetching a deleted recording returns not found and deleted recordings are not returned in the list.

Prior to this release, when a recording was deleted, metadata was only available in the Twilio Console. With this change, recording metadata is also accessible and behaves the same for Programmable Voice API.

Note that when a recording is deleted, the recording media cannot be recovered and no storage cost apply. The recording is set to a status of “deleted” and the metadata is preserved for a period of 40 days, during which time the metadata is still available.

Flex Insights Historical Reporting now enables users of Analytics Portal outside of Flex to drill down to conversations in their hosted or self hosted Flex. When users click on individual calls, chats and emails in Historical Reporting they will no longer be sent to a standalone web application outside of Flex.

The Conversation screen in Flex provides more features, supports programmability and is integrated with other Flex features. All future improvements will also be added only to Flex’s Conversation screen. The conversation screen outside of Flex is now deprecated and will not get any new improvements.

We encourage existing customers to set up their Flex instance domain so they take advantage of this new feature. To keep the user experience intact users in all existing accounts by default drill down to the legacy conversation screen. Users in newly created accounts by default drill down to hosted Flex.

Voice Insights Call Summary events sent to Event Streams have been updated. The new changes from v1 bring parity with the parameters returned by the Call Summary REST API, including created_time, queue_time, edge_location, queue_time, application info (such as app.name, app.version), and the trust object which includes verified_caller and branded_call details. If you are currently subscribed to one of the Call Summary event types, you will need to re-subscribe to consume the new version and receive the new fields that were added to v2.

The Conference Summary and Participant Summary from Conference Insights is now available via API. Both summary records return useful metadata about the conference and its performance. The Participant Summary API is the first post-conference API to provide access to participant data; previously participant information was only retrievable via API while a conference was in-progress.
