Twilio Changelog

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.

Check out the Event Streams product or documentation on how to utilize this new feature!

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!

Twilio's response to POST to /Participants API will now return a queue_time parameter, which provides an estimated time the call will be queued before it is executed. 

The latest Twilio Voice mobile SDKs (iOS and Android) now expose a new AudioOptions API. This gives developers fine-grained control of their app’s audio experience by enabling audio processing operations on the local audio source. The following webRTC options are now exposed via the new API:

• Noise suppression
• High pass filtering
• Set jitter buffer max size
• Set jitter buffer min delay
• (Android only) Echo cancellation
• (Android only) Automatic gain control

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

HTTP callbacks (webhooks) for inbound WhatsApp messages that originate from a Meta Click-to-WhatsApp advertisement now include a new ReferralCtwaClid parameter. This parameter contains the unique identifier generated by Meta representing the WhatsApp message conversation initiated by a user’s ad click. Customers can now use this parameter to integrate their WhatsApp business messaging events with Meta’s Conversions API (see ctwa_clid) to optimize Meta’s ads targeting and performance measurement.
