Twilio Changelog

In 2H 2023 Twilio will be updating the media IPs and port ranges for SIP and Voice SDK 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 10000-60000.

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 will need to update your network infrastructure to ensure that you have whitelisted the full IP and port ranges. Failure to do so will result in one-way audio and dropped calls.

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.

Super SIM Usage Insights now lets you export a CSV file containing your SIMs’ usage record data. With just the click on a button, you can download an extract of the table currently being displayed in the browser. Having this data in the form of a CSV allows you the flexibility to perform subsequent analysis using any application of your choice – a database, spreadsheet, or data visualization tool.

All of the Usage Insights tabs support the CSV Download feature:

• Usage by Time
• Usage by SIM
• Usage by Fleet
• Usage by Country
• Usage by Network

Access CSV Download for Super SIM Usage Insights in Console by navigating to Monitor > Insights > Super SIM and clicking on the button labeled “Export CSV”.

We are excited to announce that the Conversations API is now generally available in Ireland (chat only). The availability of Conversations API in Ireland gives you control over where you data is processed and stored. It also offers data processing that is closer to your applications, therefore reducing latency and improving performance.

Twilio Microvisor is now in Public Beta. Microvisor provides managed connectivity as well as managed security for the lifetime of IoT devices. With Microvisor, you can continuously debug and improve a connected hardware product after it has been mass-manufactured and deployed to the field – by offering unbrickable over-the-air firmware updates and secure remote line-by-line debugging live on deployed devices. Microvisor leverages Arm TrustZone to achieve security and failsafe connectivity through hardware-level separation of communications and application and a hypervisor architecture.

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:

• the SIM’s current billing period start and end timestamps (1 month duration)
• its data consumption within this timeframe
• its monthly data limit, as defined by its Fleet

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

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.

This solution enables organizations using Avaya Aura Contact Center solutions that include the Avaya Enterprise Session Border Controller (ESBC) to connect to the PSTN via Twilio Elastic SIP Trunking.

Twilio now supports new error codes for "Rejected" and "Paused" WhatsApp Templates. With Twilio Alarms, you can now get notified via webhook or email when these and other errors occur.

When a WhatsApp template gets rejected, Twilio surfaces a new error code of 63040 and will include the reason from WhatsApp.

Likewise, if a WhatsApp template is paused due to quality concerns from WhatsApp, Twilio will surface an error code of 63041. The message also contains when it will be unpaused. A template can be paused by WhatsApp when different users report messages sent using that template, or when users block the number after receiving those messages.

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.
