Super SIM has been added to the API Explorer. Use the API Explorer to test out Super SIM API calls from Console.

You can use the API Explorer to perform actions that can currently only be done through the API, such as sending SMS Commands to your Super SIMs, from Console.

Voice Insights Subaccount Dashboard provides an overview of subaccounts and the ability to identify those subaccounts which are performance outliers for common metrics including call volume, average length of call, answer ratio, post-dial delay, SIP responses, and more.

The dashboard displays subaccount performance over defined time periods and can help shine a light on accounts disproportionately impacted by call quality and subjective user experience degradation.

Voice Insights Subaccount Dashboard provides multiple views of the data with export capability. Filtering is available for date range, time zone, account SIDs, and call volume percentiles.

For more information see the documentation.

You and your team can now control who receives what critical communications from Twilio.

Earlier, we were sending emails like developer updates and pricing changes to the account owner.

Now, we will let you decide what notifications you want to receive, through role based access control.

As the Owner or Administrator of your account, you can customize which roles in your organization will receive each of these five types of Twilio notifications

• Pricing Updates: Updates to product prices and rates
• Regulatory and Compliance Alerts: Alerts on regulatory and compliance issues/requests
• Developer Updates: Updates to Twilio APIs, helper libraries and other developer tools
• Legal and Privacy Updates: Updates to our legal terms, such as a our Terms of Service or Privacy Notices
• Security and Fraud Alerts: Warnings about active fraudulent attacks and potential security vulnerabilities

As the Developer, Billing Manager, or Support person, you can manage the notifications that the Owner or Administrator of your account has already opted you into.

Start managing your notification preferences now.

Check out this blogpost to learn more about managing your notifications.

It is now possible to track the status of each message in a Conversation with the Delivery Receipts feature for the Conversations API.

The same statuses you rely on for your messaging functionality are now supported for the Conversations API, offering instant status updates like "sent" or "delivered" via REST API. These Receipts show detailed information on each message in a conversation, including the "read" status for WhatsApp.

Aggregated statuses are visible directly in the REST API Messages resource and you are able to see individual receipts by setting up a dedicated webhook or through the Receipts API resource. Direct SDK exposure is also to follow soon.

Check documentation and use-cases for more information!

Twilio Voice Client Mobile SDK for Android and iOS now have the CallerInfo object and TVOCallerInfo class to represent information about the caller. It can be used to display a trust indicator to the recipient when an incoming call, from the public telephone network, has been verified under the SHAKEN/STIR framework.

A verified call that has been given the highest attestation under SHAKEN/STIR means that the carrier that originated the call both (1) knows the identity of the caller, and (2) knows the caller has the right to use the phone number as the caller ID.

When your application receives a request webhook that has the new StirStatus parameter, all you have to do is <Dial><Client> and Twilio will implicitly pass the StirStatus to the Mobile Client.

Twilio SendGrid now provides two security features that allow you to verify that email event data is being posted by Twilio SendGrid: a Signed Event Webhook and OAuth 2.0. These security features are independent of one another and can be used together.

Twilio SendGrid’s Signed Event Webhook uses the Elliptic Curve Digital Signature Algorithm to sign requests. The signature allows customers to verify that event data is being posted by Twilio SendGrid.

OAuth 2.0 for the Twilio SendGrid Event Webhook allows customers to verify that Twilio SendGrid is properly authorized by them to post to their URLs using the Client Credentials grant type.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.20.

Other notable features include:

• Notification to signal connectivity issues: Users will now be notified if Flex UI has lost network connectivity and is trying to reconnect.
• Initialization error page: If Flex UI encounters an error during initialization, users will now see details of the error and they can download a report which will provide technical details for troubleshooting.
