Twilio Changelog

Effective October 10, 2023, Twilio will migrate the public media IPs and port ranges for Elastic SIP Trunking calls, Programmable SIP calls, Voice SDK calls, Flex calls, and SIPREC sessions in all regions. 

We’re moving from a per-region IP range allocation to a single global range (168.86.128.0/18), and we’re expanding the media port range from 10000-20000 to 10000-60000. We’re soft launching the new range as follows:

• September 26, 2023: 1% of all calls will use the new range
• October 5, 2023: 20% of all calls will use the new range 
• October 10, 2023: 100% of all calls will use the new range

Impacted Edge locations include: Sydney (AU1), São Paulo (BR1), Dublin (IE1), Frankfurt (DE1), Tokyo (JP1), Singapore (SG1), Ashburn (US1), Umatilla (US2). After the migration, Voice SDK calls can select US2 for GLL edge location selection.

We’re providing testing capabilities and we’ll offer opt-in for production traffic before the migration begins; however, these testing capabilities are intended for non-production traffic only. 

The Flex Plugin Library is a collection of ready-to-install Flex plugins. It simplifies the discovery and installation of Flex plugins.

Note: The Manage Plugins page in Flex Admin Dashboard has a new tab for the Plugin Library. Erstwhile Plugins and Plugin releases tabs have been renamed to Custom plugins and Custom plugin releases.

Most plugins in the Library are open sourced. They can be cloned, customized and uploaded as Custom plugins via the Plugins CLI. The Plugin Library has no impact on how Custom plugins work.

Head over to the Flex Admin Dashboard to browse and install plugins from the Library.

On 10 October 2023 Twilio will be updating the public media IPs and port ranges for SIP and Voice SDK calls in all regions. We are 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 10000-60000.

Old IP and port ranges will no longer accept or send traffic after 10 October 2023 but will need to be kept open in your infrastructure until that time. We are making this change to provide flexibility, reliability, and scalability for the next ten years. You will need to update your network infrastructure to ensure that you have allowlisted the full IP and port ranges before 10 October 2023. Failure to do so will result in one-way audio and dropped calls.

Impacted Edge locations include: Sydney (AU1), Sao Paulo (BR1), Dublin (IE1), Frankfurt (DE1), Tokyo (JP1), Singapore (SG1), Ashburn (US1), Umatilla (US2).

Twilio Interconnect connections are excluded from these initial changes, but will be migrated separately in the future.

This release reversed changes made to the usage of Sync for outbound, transfer and conference state workflows that were introduced in v1.33. For full details on the changes included in this version read the release notes.

For more info on what changes were introduced in v1.33 and are now being reversed, refer to ‘Changes to Sync usage in Flex UI’ in the Flex UI release notes.

This release addresses issues around increased plugin loading time and list of agents not displaying correctly when the hidden filter property is configured.

This release adds keyboard shortcuts to the Agent Desktop of Flex UI so that agents can perform common actions quickly. This includes accepting and switching between tasks, putting voice calls on hold and mute, and much more. Full details of the available shortcuts see thethe User guide.

Additionally developers can edit the default shortcuts and add custom shortcuts. Details on how to do this are available here.

For full details on the changes included in this version read the release notes.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.32.

This release of Flex UI introduces a Degraded mode for Flex UI and improvements to Status Report. Now Flex UI will initialize with limited capabilities, even if some of the components like SDK’s (TaskRouter, Conversations, Voice or Sync) are down. 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.

For more information check our documentation. Check how to enhance and customize queues monitoring programmatically.

For more details on this release, please visit the release notes for Flex UI.

Reminder: You can pin to individual versions of the Flex UI or manage your Automatic Updates within the Flex Admin UI.
