To use Facebook Messenger and Google Business Messages channels, you must upgrade to Flex UI 2.4.0 or later. For more details about these features and other Flex UI 2.4.0 updates, see the Flex UI Release Notes for v2.x.x.

The Real-time Queues View now offers four new metrics to better manage your contact center: average speed of answer (ASA), average handle time (AHT), missed invitations, and average abandon time. 

These new metrics are available in Flex UI 2.4.0 and later. For more details about this feature and other Flex UI updates, see the Flex UI Release Notes for v2.x.x.

We are excited to announce that Flex UI 2.4.0 is now available with new filters in the Real-time Queues View.

UPDATED MIGRATION SCHEDULE: On 23 January 2024 Twilio will be updating the media IPs and port ranges for SIP and Voice SDK calls in all regions to 168.86.128.0/18 and expanding the UDP port range to 10000-60000. Old IP and port ranges will no longer accept or send traffic after this date. Before this new migration date, we'll perform two days of testing with limited traffic, impacting Flex, SIP, and Voice SDK calls using the old IP and port ranges. Learn more.

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

If you’ve already updated your network infrastructure to allowlist the full IP and port ranges and made test calls for your Twilio applications, you can now enable your accounts for production traffic.

Effective February 21, 2024, Twilio will expand the Interconnect media IPs and port ranges for calls in all regions; we’ll also expand the RTP port range to 10000-60000 UDP. 

We’ve started migrating our non-Interconnect traffic, and we’ll migrate all Interconnect traffic to the expanded port ranges listed below before February 21, 2024. 

We’re making this change to improve the flexibility, reliability, and scalability of our Voice products. We previously communicated this change in November 2022 via Twilio Changelog. 

Update your network infrastructure to allowlist the new IP and port ranges below (in addition to the IP and port ranges your network infrastructure currently allows).

• 168.86.128.0/18
• UDP port range: 10000-60000 (expanding from 10000-20000)

For example, you will need to update your firewall and BGP prefix if you have a Cross Connect and Encryption Domain if you have a VPN.

Lastly, keep old IP and port ranges open in your infrastructure after February 21, 2024; these ranges won’t be able to accept or send Voice media traffic after this time, but they need to stay open for signaling and API traffic.

If you don’t take action by February 21, 2024, you will experience one-way audio and dropped calls.
