Twilio Changelog

We are excited to announce that Flex Outbound dialing and Dialpad are now GA! Thank you to all our beta users for all the feedback you have sent us during the beta period.

This release brings improvements in quality and reliability and solves several known limitations that include:

• Improved and more granular error reporting when an outbound call fails
• Flex agents can no longer place concurrent outbound calls
• Recordings are no longer stopped when an outbound call is transferred

To get started, refer to the Flex Dialpad documentation

Native Dialpad GA is released in Flex UI 1.28. For more details on this release, please visit the release notes for Flex UI

You can now create a segment with ‘month’ and ‘year’ time units. Previously, ‘days’ was the only time unit available. For example, you might create a segment of contacts who opened an email in the last 2 months. Learn more about segmenting contacts in the Knowledge Center.

Twilio SendGrid's Deliverability Insights is a streamlined in-app dashboard that empowers you to monitor and optimize your email program health. Deliverability Insights provides an actionable view of your email delivery performance over time with metrics segmented by top mailbox providers and consultative tool tips sourced from the email experts.

Deliverability Insights also includes new Bounce Classifications, which categorize more than 30 million cryptic SMTP responses into 7 digestible categories, helping you understand why messages are bouncing and what you can do about it.

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.

The Flex Plugins CLI’s local development server is now Generally Available. It enables developers to run multiple plugins on a local instance of Flex. It can load plugins either from the local source directory of a plugin or those that are currently deployed on your Flex application. This feature makes it easier and quicker to test a plugin you are developing locally with other plugins. Additional features include

1. Ability to specify a version of a plugin to load with a new param @version
2. Support for --port that lets you choose the port to start your developer server.

Upgrade your plugins to use the latest version of the Flex Plugins CLI and refer to our docs for more details.

We have introduced a solution for Cisco-based Unified Communications infrastructures that enables the Cisco Unified Communications Manager (CUCM) to gain PSTN access using the virtual Cisco Unified Border Element (vCUBE) and Twilio Elastic SIP Trunking. This combination enables an organization using Cisco’s vCUBE to connect to the PSTN via Twilio Elastic SIP Trunking. You can learn more about this solution by referencing Twilio Elastic SIP Trunking Solution Blueprints.
