We are keeping your runtime up to date in accordance with industry standards. Based on the Node.js support schedule, Node.js v14 will no longer be in Maintenance long-term support (LTS) status after April 30, 2022. Production applications should only use releases of Node.js that are Active LTS or Maintenance LTS.

Your currently deployed functions will continue to execute on the existing Node.js v14 runtime if no changes are made

Follow these instructions to upgrade, test, and deploy your code and ensure a safe transition to Node.js v16.


This release improves Flex UI’s resiliency by updating functionality used in conferences, outbound calling and voice transfers to remove dependencies.

[U.S. A2P 10DLC] Updates to the Campaign Creation Process Beta

Twilio has released changes to the US A2P 10DLC Campaign creation process in the Twilio API and Twilio Console to reflect the latest ecosystem guidelines. These changes include collection of new fields regarding user consent (e.g., opt-out keywords and auto-reply messages), as well as enforcement of length requirements to existing and new fields. Please read more about this change from the Twilio support article, and check out code samples and API guidelines from Twilio docs.


Twilio C# Helper Library major version 6.x is now available.We ensured that you can upgrade to the 6.x version without any breaking changes

Behind the scenes C# Helper is now auto-generated via OpenAPI with this release. This enables us to rapidly add new features and enhance consistency across versions and languages.

To learn more about the C# Helper Library, check out our docs.


Twilio Alarms, a near real-time monitoring and alerting experience for Twilio customers, is now Generally Available (GA).

The first full scale implementation of Alarms supports Error Logs. This enables you to proactively monitor error logs at the minute level and receive a notification whenever there is a spike in errors, warnings, or informational events of interest, across your Twilio applications.

You can learn how to create and use Alarms with this Twilio guide or watch this demo.

We are sunsetting our old Alert Triggers product. If you have created Alerts on our old platform, they have already been migrated onto this new Alarms platform. You will be able to access these in the Manage Alarms page


In 2H 2023 Twilio will be updating the media IPs and port ranges for Frontline calls in all regions. We will be moving from a per-region IP range allocation to a single global range; 168.86.128.0/18. Additionally, we will be expanding the media port range from 10000-20000, to 1024-65535.

We are making this change to provide flexibility, reliability, and scalability. There is no action required at this time, and we will provide a more precise timeline approximately six months before the change. At that time you may need to update your internal network infrastructure to ensure that you have whitelisted the full IP and port ranges. Failure to do so could result in one-way audio and dropped calls.

Programmable Voice

Upcoming changes to withheld caller ID behavior for <Dial> calls GA

Twilio is changing how we persist caller ID information for <Dial> calls where the inbound caller ID is withheld; e.g. ANONYMOUS, RESTRICTED, etc. Today Programmable Voice translates the alpha string into digits. This behavior will change and we will begin to persist the alpha string from the inbound call to the outbound <Dial> leg for calls where the caller ID is withheld by the calling party.

This represents a significant change in the behavior of our APIs and developers will need to ensure that their systems can gracefully handle alpha characters in the To and From fields for requests and responses to the /Calls API, in TwiML,webhooks, and in status callbacks.

If the callerId parameter is used with the <Dial> verb, the outbound caller ID will reflect what was provided with callerId, regardless of the caller ID on the inbound call.


Twilio SendGrid Platform

Twilio SendGrid is Updating our Mailbox Provider Stats Features GA

Twilio SendGrid has always grouped your email statistics by mailbox provider in our console. This allows you to easily see how your email is performing at Yahoo compared to Microsoft, for example. Our system also helps clean up this data by grouping mailbox providers together. On November 16, 2022, Twilio SendGrid will release an update to our current Mailbox Provider groupings that will make this part of our application even more powerful. Specifically, we will be adding more mailbox providers to our list, increasing from 50 to almost 250. This will result in far less data being lumped into the “Other” bucket when you review your mailbox provider statistics.  Check out our blog post to learn more about the change and see examples for more information.


We are launching a new attribute `requireMatchingInputs` within <Prompt> verb which is used in conjunction with the `for` attribute to prompt the caller to enter a specific payment detail twice. The first <Prompt> verb prompts the user to enter a given payment information. 

The second <Prompt> which contains `requireMatchingInputs` set to `true` will give the caller a different prompt asking the caller to enter the information again. Once the customer enters the information, both inputs are validated against each other and if they match, they will be sent to the downstream payment gateway for processing. 

This attribute works for ACH-debit <pay> transactions of type purchase/tokenization that require users to enter a bank account number or routing number. This enhancement was introduced to catch any user input errors upfront, reducing the error rates reported by payment gateways to meet the error thresholds defined by NACHA.

For more information about this feature, check out the API Docs.

When requesting a Super SIM eSIM Profile from the /ESimProfile API, you can now request that the eSIM profile be reserved with a matching ID by setting the new generate_matching_id request parameter to true. When you reserve a profile this way, you don’t need to provide the EID of the eSIM that will use the profile, which depending on your use case may be very difficult to know ahead of time or obtain. 

When you want to download and install the eSIM profile, you will need to provide the matching ID to your device along with the SM-DP+ URL, both of which can be read from the ESimProfile when your reserved profile is available. The combined SM-DP+ URL and matching ID is often referred to as an “activation code” and often provided to end users via a QR code that they scan with their device during the workflow to add a new eSIM profile. 

Refer to the docs to learn more about eSIM Profiles and different eSIM download methods.


Current Data Limit Usage for Super SIM in Console GA

If a SIM exceeds its data limit, it won’t be able to use any more data until the data limit resets at the end of its current billing period. Today, the Super SIM details page in Console now allows you to easily identify how close a particular SIM is to reaching its monthly data limit. There is a new section on the page which shows:

Use the data limit usage information to determine whether you need to take action such as:

  • Move some SIMs to another Fleet with a higher data limit
  • Update the data limit on the Fleet your SIMs are assigned to

current-data-usage-super-sim

Access the Super SIM details page in Console via Develop > Super SIM > SIMs and selecting one of the SIMs on the list page. Alternatively, you can also check how close a SIM is to hitting its data limit via the API by following these steps in the docs.


Programmable Voice

New Audit Events for Voice Recordings and Transcriptions GA

The following new Monitor Events have been created for Voice Recording and Transcriptions: recording.created, recording.updated, transcription.created and recording.bulk-delete.created to track bulk deletions from Twilio Console.  In addition, we have updated the recording.deleted event to track pci-recording automatic deletion after 72h. The transcription.deleted event has also been updated to track deletion from the transcription detail page in the Twilio Console. These new and updated events are available in the Twilio Console and in the Audit Event/Monitor Event API. Monitor Events are a Twilio platform feature that provides comprehensive event-logging and change-tracking for Twilio resources. 

With this release, developers can improve audit of their voice applications and have granular visibility on recordings and transcriptions to contribute to their security and compliance requirements.
