Beta Connections Engage

Session Window Computed Traits Public Beta

Session Window Computed Traits is available to all Unify+ and Engage customers. You can now define a session window duration (e.g., 30 minutes of inactivity) that determines when a session ends, and automatically reset the value of a computed trait when it does.

This enables traits that reflect behavior within the current session only, unlocking powerful session-scoped logic built on top of our real-time event pipeline.

What this means for you:
You can now build smarter, session-aware experiences without handling any session tracking logic yourself. A few examples:

  • ⚠ Anomaly detection: Flag users with 10+ failed login attempts in a single session

  • 🗺 Short-term personalization: Show banners for travel cards if viewed in the same session

  • 💬 Support context: Surface recent session activity to support or sales agents

  • 📍Routing: Direct users to different flows based on in-session actions

You’ll now have more precise targeting, smarter personalization, and richer context, all in real time.

Frontline

Frontline is entering EOL, here’s what that means for customers

Twilio Frontline was built to help customer-facing teams stay connected on the go, whether that meant real estate agents closing deals from the field or healthcare workers checking in on patients. But as customer needs evolved, it became clear that a one-size-fits-all mobile solution couldn’t keep up with the demand for flexibility, deep integration, and control.

Frontline entered End of Sale on February 9, 2023, and since then, we’ve focused on helping teams transition to solutions that better fit their unique workflows. Building on that direction, we’re now officially retiring the product on September 30, 2026. The app will remain available to existing customers through that time, but is no longer under active development.

What customers can do next

We recommend taking a look at Twilio Flex for customizable contact center workflows, or one of these mobile-first partners:

  • SpokePhone: Our preferred partner for most mobile-first use cases like sales, service, and field teams. SpokePhone has deep integration with the Twilio platform, supports Voice and all Conversations channels, offers robust call routing, transfers, and analytics, and works seamlessly alongside Flex deployments.

  • Quo (previously OpenPhone): Best for teams that only need Voice, SMS, and MMS. Features include a collaborative team inbox, AI-powered call transcription and summaries, voicemail transcription, and automated SMS replies for faster customer response.

  • Fastcall: Ideal for Salesforce-centric teams. Provides deep integration with Salesforce tools, supports Voice, SMS/MMS, and additional channels like WhatsApp, and includes AI-based conversational insights.

For support navigating options or finding the right fit, customers can connect with their Twilio Account Team or reach out to Sales.

Twilio is grateful for everything customers have built with Frontline, and is here to support thoughtful, seamless transitions as teams plan what’s next.

Here’s to what gets built next,

–Team Twilio
