Product changelog and announcements

In 2H 2023 Twilio will be updating the media IPs and port ranges for Flex calls in all regions. We will be moving from a per-region IP range allocation to a single global range; 168.86.128.0/18. Additionally, we will be expanding the media port range from 10000-20000 to 1024-65535.

We are making this change to provide flexibility, reliability, and scalability. There is no action required at this time, and we will provide a more precise timeline approximately six months before the change. At that time you will need to update your network infrastructure to ensure that you have whitelisted the full IP and port ranges. Failure to do so will result in one-way audio and dropped calls.

In this version of Flex UI we have updated the Status Report, formerly known as the Debugger UI, to now include a summary of Flex UI's operation status for each user. The Status Report is now available in GA and includes debugger logs, Twilio service status information and whether Flex UI is running in degraded mode.

Find out more about the updated Status Report on the Troubleshooting Flex UI page.

This release also improves Flex UI’s resiliency by updating core functionality used in conferences, outbound calling and voice transfers to remove Sync as a dependency.

TaskRouter now supports the evaluation of Activity name and SID in Worker expressions for the Worker-list API.

For example, developers can use this to fetch workers in different activities
using GET /Workers?TargetWorkersExpression=activity_name in ['ABC',
'XYZ'] or to fetch workers using a partial name match using GET /Workers?TargetWorkersExpression=activity_name contains 'MNO'.

For more detailed information please refer to the expression syntax documentation and the Worker Resource documentation.

Twilio Flex’s Agent Desktop has been tested in Microsoft Edge, which can now be used as a supported browser for Flex UI versions 1.31.2 and above.

For more information, see the Flex UI Requirements page.

TaskRouter now emits events for Workspace, Workflow, and Activity resources upon create, update, and delete operations.

For more detailed information please refer to the Events
Reference documentation.

Twilio Flex can now be used to develop compliant healthcare applications that contain protected health information (PHI) for organizations that are subject to the Health Insurance Portability and Accountability Act (HIPAA). Twilio will sign Business Associate Addendums (BAA) with covered entities and business associates for HIPAA Eligible Products and Services.

Learn more about how to build on Twilio for HIPAA compliance.

We changed the TaskRouter out-of-box Task Channel’s friendly name from “Programmable Chat” to “Chat”. The unique name “chat” did not change. This is mostly just for information and should not have a significant impact on how you use TaskRouter or Flex.

We are excited to announce that Flex UI 2.0 is now available in Public Beta.

We are excited to announce that Flex Conversations is available in public beta.

Flex Conversations requires Flex UI 2.0. See the Flex UI 2.0 docs for more info and how to perform a migration.
