Twilio Changelog

Starting May 9, 2024, Twillio will remove any phone range blocks on your account that have been active for longer than 30 days.

In the past, some accounts received a notification that fraud was detected on those accounts and that Twilio enacted blocking for certain prefixes. These blocks were internally set using the messaging opt out functionality which is why outbound messages destined for these blocks fail with Twilio error code 21610. As there is no way for customers to control this functionality and since fraud activity tends to dissipate after blocking, we will be removing these blocks from those accounts.

What do you need to do? We recommend regularly reviewing your SMS geo permissions and only enabling countries where you intend to send messages and incur messaging costs. This is a more efficient method to prevent unwanted messages without the risk of blocking legitimate traffic. To enable or disable Geo Permissions, go to your Console’s Geo Permission settings.

Recently, a change was made to allow workers to change from one Available activity state to another while they have task reservations. Reserved tasks will remain with the worker until the worker accepts or rejects them, or until the reservation timeout is reached.

Previously, a worker with a task reservation could not change their status from one Available activity state to another while a task  was pending.

This means that when a worker changes from one Available activity state to another, they might still have reservations for their previous activity state. For example, if a worker’s activity state is High Value Tasks and they change their state to Low Value Tasks, that worker may still have pending High Value Tasks reservations. The worker would need to accept or reject those reservations. If the worker doesn’t take any action, the tasks will remain reserved until they reach the reservation timeout.

Recently, support for JitterBufferSize was added for conference instruction in the TaskRouter API. If you experience high call latency on conference calls, you can adjust this setting to improve call quality.

As of 1st April, 2024, the Global Safelist API is now generally available for Twilio Programmable Messaging. Twilio's Global Safelist API empowers you to manage trusted phone numbers that they are not blocked by Twilio’s algorithms for SMS Pumping Protection on Twilio Programmable Messaging.

We have begun enabling accounts for improved message creation API error visibility in  SMS logs and Messaging Insights in the Twilio Console as well as when you list messages via the Programmable Messaging API. Full details are available here. When your account is enabled, the banners on those console pages will update to reflect that your account is enabled. Note that accounts will be enabled on a per-account-sid basis over the coming weeks; thus certain sub-accounts may gain access before others.

The following plugins were recently added to the Flex Plugin Library:

• Agent Automation
  Enables auto-select, auto-accept, and auto-wrap-up behaviors for agent tasks based on their channel and a set of required task attributes.

• Dual Channel Recording
  Enables call recording on dual channels to enable analytics tools like Flex Insights to determine if the customer or the agent is speaking, which enhances their capabilities to detect cross-talk.

• Custom Transfer Directory
  Enhances the agent and queue transfer directories for Voice tasks with real-time data and filters.

• Supervisor Complete Reservation
  Adds a Complete button to the TaskOverviewCanvas to allow supervisors to complete pending tasks for agents.

• Activity Reservation Handler
  Enables synchronization of an agent's TaskRouter activity with the state of the tasks that they are working on.

• Hang Up By
  Enables Flex Insights reporting based on who ended the call (customer, agent, transfer, and so on).

Customers who are registering Brands, Campaigns and 10DLC Phone Numbers for A2P Messaging can now set up subscriptions to events which will notify them when a Brand, Campaign or Phone Number's status has changed. This setup and subscription is handled through Twilio's Event Streams product, which allows users to define a sink (in this case a webhook) to which an event notification will be sent for any events to which the user has subscribed - in this case, when a Brand or Campaign has been either successfully submitted or not, and whether successfully-submitted Brands and Campaigns are ultimately approved or rejected, or what a phone number’s status is in it’s A2P registration or deregistration process.

With these event notifications now 'pushed' to customers via the Event Streams framework, it will no longer be necessary to repeatedly query the Brand and Campaign creation APIs, be in limbo about the number’s registration status, or continually visit the A2P Console pages, in order to be kept up to date on registration status.

Twilio Programmable Voice now offers a React Native SDK to assist customers in building voice-powered mobile apps. React Native is a widely-adopted and actively maintained open source framework that allows web developers to create cross-platform applications using a single codebase that runs on both iOS and Android. The accompanying reference app reduces time to market by providing natively-styled UI elements out-of-the-box and demonstrates production-scale architectural best practices. The React Native SDK and Dialer reference app are both officially GA.

Additionally, we’ve added Public Beta support for the Call Message Events Voice SDK platform feature in the React Native SDK.

Check out the docs for more information, and please leave us any feedback you might have in the Twilio Voice React Native SDK Github repo. We can’t wait to see what you build!
