Twilio Changelog

Twilio extended the maximum call duration on Elastic SIP Trunking calls from 4 hours to 24 hours. This allows the business to have extended conversations that last longer than 4 hours.

With this release you are now able to enable 24 hour configuration in the settings console.

For details, check our documentation.

Programmable Voice SIPREC streams can now be started and stopped via API. This allows you to start a stream on a phone call and send that stream to one of the available partners via the SIPREC connector configuration. You can also stop streams started via the <Siprec> TwiML instruction.

For more information see our docs.

You can now read the current billing period for a Super SIM using the the new Billing Periods API allowing you to see when a Super SIM's current billing period started and will end. You can use this to determine when a Super SIM in ready state will automatically transition to active or when a Super SIM in active state will next be charged a monthly subscription fee. Learn more about this new API, see the documentation.

Additionally, data usage towards a Super SIM's data limit is measured over its current billing period. You can leverage the start and end times indicated on a Super SIM's billing period and the Super SIM Usage Records API to determine how close a Super SIM is to hitting its data limit and when the usage towards the data limit will reset. To learn more about the steps to do this, check out this guide.

You can now call emergency services in supported countries from a Conference call.

To make a Conference emergency call, you will need to add a Participant to the Conference with.

A valid e.164-formatted From phone number that can receive calls from the PSTN

The emergency telephone number has to be a valid emergency number from the same country as the From phone number

Fees apply for emergency calling in the US and Canada.

We have released significant updates for our mobile SDKs and added Chrome on iOS support to our JavaScript SDK.

The Chromium WebRTC engine in the iOS & Android SDKs has been upgraded from m83 to m88. In addition to the security and performance improvements, these mobile SDKs now use the newer “unified plan” WebRTC signaling protocol, which provides improved browser compatibility in P2P and Go Rooms. The iOS SDK has added support for running the iOS Simulator on Apple Silicon ARM64 Macs. There is a major version increment for the Android SDK to 7.0 and the minimum Android API level has been increased from 16 to 21.

The 2.17 JavaScript SDK now supports the Google Chrome browser on iOS versions 14.3 and above.

For a full description of all the changes, see the Android SDK 7.0 changelog, iOS SDK 4.6 changelog and JavaScript SDK 2.17.
