Twilio Changelog

To provide the best audio experience for multi-party Voice Conferences we automatically suppress the background noise of participants who are not speaking. However, in a very low-noise Contact Center environment, customers may believe the agent has hung up the call when the agent stops speaking. To avoid this problem we have added a new audio setting called Background Noise Passthrough.

When this setting is enabled the background noise of the agent will be passed through to the customer and provide an audible indication the call is still in progress. This can result in fewer abandoned calls by customers.

To learn more, visit the Conference Settings in the console.

Request Inspector now shows API requests made to Twilio's Voice APIs for call creation, call modification, conference participant creation, conference participant modification, and conference modification with respective parameters. Previously developers would need to enable logging of API request parameters in their applications and manually compare their application logs with the call behavior in Twilio Console to know if a call ended or a participant was muted using the API. These requests are available to view in Console for both completed and in-progress calls. This change simplifies debugging of call behavior issues by providing the API requests, TwiML requests and responses in one place.

Twilio now supports Amazon Polly Neural Text-to-Speech (TTS) Voices allowing you to use higher quality voices with TwiML <Say> in your voice applications. The ground-breaking improvements in speech quality come through a new machine learning approach which converts text into lifelike speech. Amazon Polly Neural voices are currently available in two speaking style voices - Newscaster and Conversational and across four languages - English (British), English (US), Portuguese (European), and Spanish (US).

Try these voices in your IVR applications by selecting them in the TTS console or by setting them in your TwiML <Say> attributes. For more information on the voices and on pricing, please visit Twilio Text-to-Speech docs and Amazon Polly docs.

This release of Flex UI introduces a pilot release of Advanced Team View Filters. This feature allows supervisors to search or filter their agents by name or activity or use custom, programmatically defined, filter criteria like teams or skills.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.17.

This release of Flex UI introduces an Initial Audio Device Check. This feature allows you to perform an audio device availability check when Flex starts up to make sure you are ready to receive voice calls.

Initial Audio Device Check is currently available as a Pilot feature. To enable it, visit the Pre-Release Features Page. You can learn more about this feature within our documentation.

For a full changelog, visit the Flex UI release notes.

Reminder: You can pin to individual versions of the Flex UI or manage your Automatic Updates within the Flex Admin UI.

Programmable Voice, Elastic SIP Trunking, and Programmable SMS can now support compliant healthcare uses cases that contain protected health information (PHI) for organizations that are subject to the Health Insurance Portability and Accountability Act (HIPAA). Twilio will sign Business Associate Addendums (BAA) with covered entities and business associates for HIPAA Eligible Products and Services.

Twilio Functions makes it easy to deploy custom code onto Twilio to support your communications use cases. Today, we're introducing a new Serverless API endpoint that lets you retrieve debug logs for Functions executions. In addition, the Twilio Debugger will now show Warning and Error level log messages added to your Functions code. You can tail logs from deployed Functions locally via the latest version of the Serverless Toolkit.

To learn more about the functionality, visit the Logs page in the Serverless API documentation.

Today we are excited to announce that we are open sourcing three video collaboration applications, one for iOS, one for Android, and a ReactJS one for the Web. These fully featured apps can be deployed to the Twilio cloud in minutes for your own personal, globally scalable, multiplatform video collaboration solution.

Access to the source code will empower developers to tailor the application to their use case and create a truly unique collaboration experience. The code also provides a canonical reference for developers building on the Twilio Programmable Video APIs.

For additional information on getting started see the blog post here and links to the source code repos are below.

We have added new filter dimensions to the Voice Insights Dashboard. The new filters are:

The Client Insights beta ended in August 2019 with the general availability of Voice Insights. We have continued to respond to requests made to the preview API, but we will cease responding to requests to beta API resources on May 1, 2020.

If your application consumes the preview API resources you will need to update your code to use the new endpoints. We have created a migration guide to assist with update your applications: https://www.twilio.com/docs/voice/insights/client-insights-preview-api-shutdown/client-insights-preview-api-migration-guide

For more information about the shutdown of the Client Insights preview API see https://www.twilio.com/docs/voice/insights/client-insights-preview-api-shutdown
