Unified Login for SendGrid Marketplace Customers
SendGrid marketplace customers can now take advantage of the

When accessing your SendGrid marketplace account from one of the marketplace integrations - Microsoft Azure, Google Cloud, Heroku, or Amazon Web Services - you will be prompted to provide an email address to create your Twilio login. If you already use another Twilio product and have an existing Twilio login, you can use that email address and password for SendGrid access.
This will be rolled out over the next couple weeks for all SendGrid marketplace customers. For more details, see the documentation

Voice Insights now tags HD audio calls
Voice Insights now tags calls as 
 when they connect with the AMR-WB or Opus codec.
Use the tag to confirm your endpoints negotiated what you configured, and to correlate HD usage with transcription accuracy, AI agent performance, and customer satisfaction.
Calls that carry HD audio are tagged as 
 when the longest portion of the call connects to a component or another endpoint that does not support HD. Twilio converts the audio to narrowband to keep the call connected.

Segment Conversation Memory Integration now in GA
The Segment Conversation Memory Integration is now in GA. You can now sync long-term customer profile data, like identity and lifetime value, from Segment into the sub-second recall of Conversation Memory, enabling both AI and human agents to instantly access unified context during live interactions. This eliminates cold starts, reduces repetitive questions, and delivers highly personalized, continuous customer experiences across all channels.
The integration continuously syncs long-term customer profile data, such as identity and historical traits, from Segment directly into Conversation Memory. Customers configure this transfer using either "Memory Sync" to rapidly import their entire profile database or "Memory Destination" to target specific user cohorts via Segment Audiences. During setup, Segment profile traits and identifiers are mapped to corresponding semantic trait groups within a Memory Store. Once active, trait updates flow in real time, allowing AI or human agents to instantly query the Memory Store for up-to-date customer context during live interactions.

Voice Insights now tells you why a carrier blocked your call and how to reach that carrier for redress.
 that block calls using analytics to return the reason header to the caller. It names the network that blocked the call and tells you how to contact them: a URL, a phone number, or an email address. Until now a blocked call showed you only a 603 response. Now you can see which network blocked it and petition them directly.
The reason header appears alongside Last SIP Response in the Call Summary, in Twilio Console, the Voice Insights REST API, and Event Streams.
If you are seeing a high volume of 603 responses, confirm your traffic is signed with STIR/SHAKEN and registered with 
 before you start filing redress requests.

Twilio Video Media SDK for Node.js now in Public Beta
The Twilio Video Media SDK for Node.js is now in Public Beta. Your server-side app can securely join a Video Group Room as a participant and work with decoded audio and video frames directly, so you can run AI and media processing such as transcription, computer vision, or compliance monitoring on your own infrastructure, without the overhead of a headless browser. 
Your app reads decoded frames from other participants and publishes frames back into the Room as a virtual camera or microphone. This Media SDK shares the Room, Participant, Track, and Access Token model of the 
, so most concepts carry over. Install it from npm as @twilio/video-node-sdk. It requires Node.js 24 or later on x86-64 Linux, and the Media SDK participant counts and bills as a standard Group Room participant.
