Programmable Voice

New Amazon Polly Neural Voices available for <Say> GA

The Twilio Programmable Voice <Say> TwiML Text-to-Speech verb now supports additional Amazon Polly Neural Voices for the following languages: Portuguese (Portugal) (pt-PT), Portuguese (Brazil) (pt-BR), German (Austria) (de-AT), Spanish (Mexico) (es-MX), and Catalan (Spain) (ca-ES).

You can try the new enhanced voices in your voice applications by selecting them in the Text-to-Speech section of the Twilio Console, by setting them in your TwiML <Say> attributes, or by configuring the Say/Play Widget in Studio. For more information on the voices and on pricing, please visit Twilio Text-to-Speech docs. 


We changed the TaskRouter out-of-box Task Channel’s friendly name from “Programmable Chat” to “Chat”. The unique name “chat” did not change. This is mostly just for information and should not have a significant impact on how you use TaskRouter or Flex.

Call Annotation API Beta Beta

The Call Annotation API allows customers to programmatically provide subjective experience details including call quality issues, spam labeling, and customer-internal tags and metadata. Customers can use the Call Annotation API to update the call summary records during or after a call. Annotations can be updated as long as the Call Summary record is addressable via the API i.e. 30 days. 

Currently the Call Annotation API is only available for the United States (US1) Region. For more information on Twilio Regions see here

Twilio SendGrid Platform

Updated Limitations to Category Statistics for All Customers GA

Twilio SendGrid started limiting category statistics for all customers on May 16, 2022. Beginning June 22, 2022, Twilio SendGrid will limit all category statistics created before May 16, 2022 on a seven-day rolling basis. This means all categories will be available for the first seven days. After seven days, the top 100 categories will be retained for free customers, and the top 1,000 will be retained for paying customers.

Customers who require access to all category statistics can use the Event Webhook to retrieve and retain the data on their own systems as long as they save it within seven days of first sending the event.

For more information about how this change works, please see the "Limitations" section of our "Working with Categories" documentation.

Many customers find that Unique Arguments, which are not limited, are the best solution for their needs. See the "Categories vs Unique Arguments: Benefits & Limitations" blog post to better understand these two tracking tools.


The new Usage by Fleet, by Country, and by Network tabs in Super SIM Insights provide even more ways to aggregate and analyze your Super SIM usage data. 

  • In Usage by Fleet, quickly identify how much data usage your most active Fleets have incurred over a user-specified time period. 
  • In Usage by Country and by Network, quickly pinpoint which countries and networks your Super SIMs have exchanged the most data with.

All tables also include a 3-dot icon on the rightmost column. This icon opens a dropdown menu that allows you to “drill down” on that particular row. Clicking on an entry in the dropdown takes you to the corresponding tab within Usage Insights and simultaneously applies that row as an additional filter.

Access the new Usage Insights by Fleet, by Country, and by Network tabs in Console via Monitor > Insights > Super SIM.

Essentials 40k and 100k Pricing and Packaging Changes GA

Effective July 1st, 2022, all Twilio SendGrid Essentials 40k and 100k packages will change. The Essentials 40k package will become the Essentials 50k package with a new price, and the Essentials 100k package price will be changed. 

The new Essentials 50k package will come with 50,000 emails/month for $19.95/month, and $0.00133/email overage. The Essentials 100k package will have a price increase to $34.95/month, and $0.0009/email overage. 


We are committed to continued investment in our infrastructure and innovation to provide the best-in-class features you need to build exceptional experiences with email. The features included in the Essentials plan and prices of add-ons are not changing at this time. You can review past invoices and update your Plan and Billing Details in the SendGrid application. If you have any questions please reach out to our knowledgeable support team.


Starting 5/30/2022, phone numbers can not be assigned to more than a single regulation of a given kind. For example, if a phone number has been assigned to a Shaken/Stir bundle, it cannot be assigned to any additional Shaken/Stir bundles. This change will help to keep our phone number assignment clean and without issue.

Functions & Assets are now in one central place Beta

Since the launch of Functions & Assets in 2017, the two have been a powerful combination. Whether you were using private Assets to store shared logic between Functions or host MP3 files as public Assets for your Functions powered Twilio Voice application. In 2019, we launched a new editor that allowed you to manage your Functions & Assets in one editor interface and using one API, but the two remained separate products in the Console. 

Today we are merging the two into one central place in the Console to reduce confusion and make them more easily accessible.

What's changing?

Not much. Any existing URLs will continue to work. If you previously had Functions or Assets pinned in your Console, you'll now see a combined "Functions & Assets" product pinned instead, with everything accessible in the same navigation bar.

Screenshot of the Functions  & Assets navigation bar

If you haven't pinned Functions and Assets yet, you'll now see them in a combined tile on the Explore page in the Twilio Console.

Screenshot of the Functions & Assets entry in the Explore page of Console

Outside these changes, you will see no other changes impacting your development flow.

We can't wait to see what you build!

Flex UI 2.0 is now in Public Beta Beta

We are excited to announce that Flex UI 2.0 is now available in Public Beta. 

1.a - Main channel as SMS and having another tasks.png

Flex UI 2.0 is a major release of Flex UI and contains a lot of long awaited updates. Here are the most notable ones: 

Setting the stage for important Flex releases

Flex UI 2.0 is a component for the new async channel platform Flex Conversations that introduces new capabilities like support for Conversations API, new Interactions API and new channels like WhatsApp and Email (coming soon). Flex UI 2.0 continues to support the legacy channels.

Providing common developer tools

Flex UI 2.0 uses the latest versions of main dependencies, like React, Material, Emotion, and Redux libraries, so not only our application is built with latest fully supported technologies, but also plugin developers can take advantage of the latest updates in these packages.

Utilizing Paste as the build tool

Flex UI 2.0 aligns with the WCAG 2.1 level AA standards and with redesigned interfaces that utilize the Twilio accessible design system Paste and integrated Paste component library for plugin developers to build accessible plugins.

For all new accounts Flex UI 2.0 is going to be enabled by default and for existing accounts, check out our Migration guide.

To learn more about all the updates go to Flex Docs.

Announcing Dual-Channel Voice Recordings by Default GA

Call recordings are now stored by Twilio in dual-channel by default for no additional cost, enabling you to process the individual participants of the call recorded. With this change, the recording audio files of a 2-party call will have two channels and contain the audio from each call leg in a separate channel. 

Prior to this release, customers needed to specify dual-channel to record each participant in a separate channel, and all audio mixed in a single channel was the default behavior. With this release, a new RequestedChannels query parameter can be used to specify whether the file should be downmixed to a single channel or downloaded as a dual-channel file. For backward compatibility, when RequestedChannels query parameter is not specified, the default download will be either mono or dual, depending on what was requested for the recording.

It’s possible to continue enabling single-party call recordings using the recordingTrack parameter to select whether the inbound or outbound audio tracks of the call should be recorded, and the recording file will always be mono and no additional tracks recorded. Voice recordings where dual-channel is not supported, such as TwiML <conference> noun and <record> verb, all audio will be mixed in a single channel file.

With this release, storing dual-channel recordings comes at no extra cost compared to single-channel storage.

Dual-channel call recordings by default is now available on all new accounts and will be gradually deployed on existing accounts.

Learn more about how it can help unlock intelligence from your recordings by increasing transcription accuracy. on the Twilio blog.


Programmable Messaging

New WhatsApp Media Content Types Supported on Twilio in Public Beta Beta

Sending WhatsApp messages with media now supports additional content types in a public beta, including Microsoft Word, Excel, PowerPoint, and certain audio files. See this document more information on all the different media types we support.


In this release of Flex UI, we have introduced a Degraded mode for Flex UI - now Flex UI will initialize with limited capabilities, even if some of the components like SDK’s (TaskRouter, Conversations, Voice or Sync) are down. In case of disruptions in Twilio services, Flex User will be able to login to Flex and perform certain tasks that are still available. For example, in the case of Twilio Voice experiencing an incident, your agent will still be able to handle messaging tasks.

Users will see a notification informing them of a possible disruption in the normal operation of Flex UI and they will be able to download a thorough report with error details and logs.

For more on error handling and reporting, check out our Troubleshooting Flex UI guide.


SendGrid Email API

Bounce Classifications now in Twilio SendGrid Event Webhook GA

Bounce Classifications are now included in the Twilio SendGrid Event Webhook. The event webhook is a powerful way for you to consume event level data to gather more insight to your email performance. Twilio SendGrid's Event Webhook will allow you to use a data aggregator of your choice and notify a URL via HTTP POST with information about events that occur as Twilio SendGrid processes your email. The addition of Bounce Classifications to the Bounce and Deferral event payloads will provide additional insight as to why an email was bounced, blocked, or deferred.

Limitations to Category Statistics for All Customers GA

Twilio SendGrid started limiting category statistics for new customers only on March 16, 2022. Beginning May 16, 2022, Twilio SendGrid will limit category statistics for all customers on a seven-day rolling basis. This means all categories will be available for the first seven days. After seven days, the top 100 categories will be retained for free customers, and the top 1,000 will be retained for paying customers.

Customers who require access to all category statistics can use the Event Webhook to retrieve and retain the data on their own systems as long as they save it within seven days of first sending the event.

Twilio SendGrid accounts created before March 16, 2022 will temporarily retain access to all category statistics created before May 16, 2022. However, access to unlimited category data is transitory and should not be expected to persist.

For more information about how this change works, please see the "Limitations" section of our "Working with Categories" documentation.

Many customers find that Unique Arguments, which are not limited, are the best solution for their needs. See the "Categories vs Unique Arguments: Benefits & Limitations" blog post to better understand these two tracking tools.


The Marchex Transcription with Conversation Intent and Outcome is now available in Twilio’s Marketplace Add-ons catalog. This Marketplace Add-on identifies the most important attributes of your phone calls such as the primary intent of the caller and outcome of the conversation, using Marchex’s AI powered conversation intelligence capabilities. To learn more about this Add-on and how to enable it for your application, visit the Marketplace Marchex Add-on in the Twilo Console.


Programmable Voice

External Storage for Call Recording is now available GA

External storage for call recordings is now available for all voice customers. Call recordings will remain to be stored at Twilio by default. Alternatively, customers can enable external storage and automatically upload recording files directly to an AWS S3 bucket without additional charges.

To determine whether the recording’s media file is stored externally or at Twilio, a new property mediaUrl has been added to the call recording resource with the full URL location of the file; this will apply also to existing RecordingUrl property from the RecordingStatusCallback. When external storage is enabled, recording files from two-party calls get uploaded as dual-channel regardless if they are requested to be mono or dual-channel. Recording resource metadata is available at Twilio until explicit deletion.

Prior to this release, recording status callbacks could be used for automating recording file download and deletion but required additional software development and additional API requests by customers to set up this workflow.

Learn more.


You can now manage the configurations related to a unique address (i.e. a WhatsApp or SMS phone number) within Conversations. This resource allows you to specify which addresses should auto-create a Conversation upon receiving an inbound message.

With this feature, you can also automatically attach a Conversation-scoped Webhook to the auto-created conversation.

Explore the Address Configuration API documentation and give it a try!


On May 3rd, 2022 responses to API requests for CSV representation of Incoming Phone Number and Outgoing Caller ID resources for both list and instance will change; specifically the order of the columns may be different.

The order of the columns in the CSV is not defined and may change when new fields are added to the API response. Your application design should be resilient to changes in the order of the columns in the CSV response.

See our docs for more information about how to leverage CSVs with Twilio.


Elastic SIP Trunking

Diversion header validation for termination calls GA

When Twilio receives termination traffic from your communications infrastructure to the PSTN, your SIP message can sometimes include SIP Diversion headers if the call was previously forwarded. Twilio will forward SIP Diversion headers it receives to the carriers.

To combat any malicious addition of Diversion headers, Twilio will now check all Diversion headers it receives that contain the Twilio domain. Twilio will verify that the phone number included in the header matches one associated with your Twilio account (either a Twilio number owned by the account or a verified Caller ID). If the header fails this check, Twilio will remove the header.

See the docs for more information.
