Twilio Changelog

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

Twilio Functions created via the Serverless API can now be integrated with your Studio Flows through the Run Function widget.

Selecting a Function to invoke in the Flow is easy. For Functions created via the Console UI choose the "Default" service, and for Functions created via the Serverless API choose the Service and Environment where they are deployed.

Twilio Programmable Call Recording now supports Single Party Recordings. The new recordingTrack parameter allows developers to select whether the inbound, outbound or both audio tracks of the call should be recorded. The inbound track represents the audio received by Twilio, and outbound track represents the audio that Twilio generates on the call. Prior to this release, all audio was captured regardless if the recording file contained one or two channels.

In addition, recordingStatusCallback will also include a new recordingTrack attribute that indicates which audio was recorded and this information will be displayed in Twilio Console too.

Learn more about this feature and how to configure recordingTrack in our Blog post announcement.

With this release, Studio Gather Input On Call widget now supports additional speech recognition features so you can fine-tune your Studio Flows for Voice. The new attributes allow you to adjust the Speech Timeout, specify a Speech Model, and control the Profanity Filter setting. All this functionality is powered by the underlying Gather verb from our Programmable Voice product.

In addition to the Gather improvements, the Record Voicemail widget now provides controls for the Trim Silence and Play Beep settings and even provides access to the Recording Status Callback URL so your application can be notified when a new recording is complete.

Finally, the Say/Play widget supports sending Digits on a call when the Play option is selected, allowing you to programmatically play DTMF tones to navigate an external IVR.

To learn more, visit the documentation on the Gather widget, Recording widget, and Say/Play widget, or just try it out now in Studio.

You told us you didn't like the fuzzy timestamps on the Twilio Debugger that said an event happened "a few seconds ago" instead of showing you the actual timestamps. We changed it.

Now you will see the actual timestamp of the event in UTC.

Prior to this release, a call established over cellular data for example, persisted over cellular data for the duration of the call even if a WIFI network became available. This is undesirable since a WIFI network is usually cheaper and requires less battery power. With this release, an ongoing call will automatically and seamlessly switch to a preferred network type when one becomes available. Network types supported in preferred order are: ETHERNET, WIFI, VPN, and CELLULAR.

Your invoices will now show your account name(s) along with the company name. If you have multiple accounts (a.k.a projects) on your invoice (multi-account invoicing), you will see the account name (a.k.a project name) for each account in parenthesis next to each account’s company name.

This addition to the invoice is to help you connect an invoice with the correct account since some customers track their Twilio projects by account name instead of company name.

You can understand more details about your invoice at Reading your Twilio Invoice. You can change your account name as explained in Can I change the name of my project.

Programmable Video 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.
