Today we are kicking off the private beta program for Twilio Live. This new channel gives developers the tools to build immersive experiences that can be directly embedded into their applications. With Twilio Live, developers have access to a low-latency, secure live streaming platform that allows speakers to reach millions while providing an intuitive end-to-end developer experience, including flexible server-side API primitives, and client SDKs for iOS, Android, and JavaScript.

With Twilio Live, developers have the building blocks to create all types of interactive live event applications such as marketing conferences, next-generation social podcasts, shopping experiences, concerts, fitness classes, education sessions, and more.

For additional information on this release, see our blog posthere.

We have introduced a solution that enables Microsoft Teams Direct Routing to gain PSTN access using the Oracle Communications SBC and Twilio Elastic SIP Trunking. This combination enables any organization using Microsoft Teams Direct Routing to connect to the PSTN via Twilio Elastic SIP Trunking. You can learn more about this solution in our blog and by referencing Twilio Elastic SIP Trunking Solution Blueprints.

We have updated the experience when searching for and buying numbers in Console. In addition to refreshing the overall look at feel, we've streamlined the filters available when searching and made updates to provide more helpful guidance when numbers are not available.

Twilio Voice Javascript SDK 2.0 is now GA! Thank you to all our beta users and for all the feedback you sent us during the beta period.

Twilio Voice Javascript SDK 2.0 represents a much-needed spring cleaning of legacy APIs, including:

• Removing deprecated methods
• Renaming classes and methods to be less ambiguous
• Implementing new features introduced in 1.x as defaults
• Completely moving to the new TwilioError class which is standardized between Voice SDKs and contains much more detailed information about errors
• Full changelog available here

Additionally, new features will only be added to the 2.0 project going forward (e.g. not backported to 1.x) so you’ll want to migrate to this new major version to take advantage.

If migrating from a 1.x version, please refer to our migration guide.

Twilio Frontline, a programmable application for salespeople and relationship managers, is now in Public Beta. This launch includes publicly available mobile apps for both iOS and Android, advanced inbound routing, native SSO integration, functionality to transfer and close conversations, and support for production-scale rollouts of a secure customer communication platform over SMS and WhatsApp.

You can read more about this launch on our blog, and if you’re ready to start building, dive in to our docs.

We are excited to announce that the support for using version 16.13.1 of React and ReactDOM on Flex is now generally available.

This allows you to use more of React’s APIs, including React Hooks, when developing your Flex plugins. You can set the React version of your Flex application on the Developer Setup Page. You are no longer required to set the UNBUNDLED_REACT argument for all your Flex Plugins CLI commands.

Review our React documentation for more details and upgrade to the latest version of the Flex Plugins CLI to get started.

Error Log events are published when an error or warning takes place on your Twilio account. These are the same events surfaced through the Twilio Console Debugger. Developers can now have these events delivered to destinations like Amazon Kinesis and webhook through Event Streams. For more information about Error Log events, read the docs here.

Following our earlier announcement, we have applied a Content Security Policy to all Flex applications on flex.twilio.com. This restricts Flex from being rendered in an iframe on unregistered external domains. To continue using Flex within an iframe, including through Salesforce and Zendesk integrations, admins must register their external domains on the Flex Settings page. We have updated our Content Security Policy to prevent potential phishing attacks or abuse by malicious third parties.

Refer to our documentation for more details.

Emergency calls will always be delivered for Twilio phone numbers in the US and Canada using Elastic SIP Trunking.

If your Twilio phone number used to call 911 does not have an emergency dispatchable address, the call will be routed to a national emergency call center where a trained agent will ask for the caller’s name, phone number and location.

To associate an emergency address with your Twilio phone number, check out our docs and API.
