Twilio Changelog

We're pleased to announce the general availability (GA) of Answering Machine Detection (AMD) filtering in the Voice Insights Dashboard in Console.

We previously announced the general availability (GA) of Call Annotations. This release extends the product's capability by enabling the use of annotations as filters within the Voice Insights Dashboard

If you have annotated calls using the Call Annotations API, these can now be visualized in the Voice Insights Dashboard. 

The Twilio Voice JS SDK now includes Audio Processor APIs, enabling access to raw audio input and the ability to modify audio data before sending it to Twilio. With this new feature, the following use cases are now easily achieved on the client side:

• Background noise removal using a noise cancellation library of your choice (“bring your own”)
• Music playback when putting the call on hold
• Audio filters
• AI audio classification
• … and more!

Check out the docs for more information on how to use the new functionality in your application. We can’t wait to see what you build!

Migrate Dialogflow ES bots to Dialogflow CX <Virtual Agents> for continued integration through Twilio, take advantage of CX's new features.

Customers seeking to establish a new connection, modify an existing one, or disconnect a connection can conveniently submit their requests within Console, eliminating the need to engage sales or support. Additionally, customers have the flexibility to adjust account permissions and reference connection configuration details directly within Console. 

To get started, navigate to Interconnect > Connections in the sidebar of your Twilio Console. 

Learn more about Twilio Interconnect on our website or docs. 

This API allows you to retrieve the real-time statistics for up to 50 task queues with a single API call. The API has a rate limit of 5 requests per second.

For more information, see Bulk retrieval of TaskQueue RealTime Statistics.

Twilio is committed to streamlining the A2P 10DLC campaign registration process and providing transparent feedback on issues that might arise during registration. To enhance this experience, we are rolling out three new error codes that will convey more specific reasons for registration setbacks, enabling you to quickly address and resolve these issues.

New Error Codes:

• Error 30907: Encountered when there is a validation issue with the website URL provided.
• Error 30908: Returned when a Campaign registration lacks a compliant privacy policy.
• Error 30909: Issued for unverifiable Calls to Action (CTA) within the Campaign registration.

To learn more about these error codes, please read the Twilio support article. For a detailed list of all error codes please visit Twilio Error and Warning Dictionary. 

We previously announced the Call Message Events feature for Twilio Programmable Voice JS and iOS SDKs earlier this year. This release extends support to the Android SDK.

The Twilio Programmable Voice SDKs now offer the new Call Message Events: User-Defined Messages and User-Defined Message Subscription resources for application developers on JS, iOS, and now Android SDKs. This release, available now in Public Beta on the latest major version of the Voice Android SDK, supports relaying custom events to and from your backend to a registered Voice SDK Client on any active call - all within the Twilio platform. By leveraging the existing signaling connection, you no longer need to set up your own communication channel between your client-side and server-side applications. This unlocks a host of advanced use cases, including:

• Relaying (and taking action on) call progress events
• In-line text transcriptions
• Upgrading 2-party call to multi-party via Voice Conference
• Presenting valuable context in your application at the right time

In coming releases we’ll bring this functionality to our React Native SDK as well as explore options to provide “out-of-the-box” event subscriptions for common use cases. Check out the docs for more information on how to use the new functionality in your application. We can’t wait to see what you build!

Effective November 8, 2023, Twilio requires all U.S.-bound messages from toll-free (TF) phone numbers to be fully verified or pending verification (meaning customers have submitted their numbers for verification).

Any blocked messages sent from an unverified toll-free number will return Error 30032 and filtered messages will return Error 30007. Twilio messaging rates still apply for blocked messages.

Please register your toll-free phone number as soon as possible to avoid impact to your messaging traffic. You may use our Twilio Console or API options to submit your verification information.

For more information, please check out our guide Toll-Free Message Verification for US/Canada.
