Product changelog and announcements

Starting October 22, 2026, Twilio Real-Time Transcriptions automatically starts transcription sessions on a second speech provider when a customer’s primary provider doesn’t connect. Failover is enabled for all existing Real-Time Transcriptions accounts on that date, and it routes only within a customer’s existing region. Use of failover is optional and can be opted out of per sub-account in Console.

The Attempt DLR event type will be discontinued after September 22, 2026 at 10:00PM UTC. Learn more about using discontinued Event Types in Discontinued Event Types.  From this point on, Twilio may stop sending new events for the Attempt DLR event types, even if you have a subscription to them. You will continue receiving events normally from any other Event Types in your subscriptions.

Twilio will begin migrating accounts to an updated Voice Recording Storage billing system.

Between Thursday, November 19, 2026 and Monday, January 4 2027, Twilio will enter a Heightened Awareness Period (HAP) to help ensure reliable message delivery during peak traffic times, such as Black Friday and Cyber Monday. 

During this period, message sending rates to U.S. destinations will be monitored and may be limited at the account level for toll-free, short code, and 10DLC numbers.

Accounts that send high volumes of messages from short codes or toll-free numbers may be temporarily migrated to Market Throughput during the HAP. Customers will be notified via email if their account is affected. Market Throughput doesn’t affect 10DLC numbers, which will continue to live on Account Based Throughput.

For more information on how throughput limits may be impacted and what actions to take, customers can reach out to their Twilio account team.

 

We’re excited to announce that Twilio integration with Salesforce Service Cloud Voice now supports WhatsApp and SMS, alongside existing support for Voice and listed on the AppExchange.

This release comes with the following enhancements:

• Route SMS and WhatsApp conversations through Twilio TaskRouter into the Salesforce Omni-Channel widget, using the same presence, skills, and capacity model as voice
• Handle messaging conversations and voice calls concurrently in a single agent console, with agent presence synchronizing across all channels on work acceptance

To learn more about setup, please see the setup guide.

ElevenLabs voices are now available in Public Beta for <Say>, powered by the Flash v2 and Flash v2.5 models for fast, natural-sounding text-to-speech. Get started by specifying an ElevenLabs voice via the REST API or in a TwiML Bin.

Using the Webhook Configuration API, customers can configure how Twilio authenticates and delivers outbound webhooks, per URL. The API consists of two resources: Webhook Settings and Webhook Rules.

Webhook Settings hold the authentication and connection configuration. Customers can secure endpoints with OAuth 2.0. Twilio fetches an access token from the customer's authorization server using the client credentials flow and sends it as a Bearer token in the Authorization header of every webhook or with Shared Key signatures. Customers can also configure delivery behavior like timeouts and retries.

In Spain and France, an incoming call intended for a non-Spanish or non-French destination that is then forwarded internationally while presenting a Spanish or French domestic caller ID is now blocked, in line with local regulatory requirements.

Verify Custom Templates give you the flexibility and security to use custom SMS/RCS and Voice message templates beyond standard defaults or pre-approved options.
