FAQs

Yes. Flex is an incredibly flexible solution. You can integrate Flex’s contact center functionality and features directly into any homegrown or third-party application like a CRM—and our new Flex SDK makes the process simpler.

Yes. Flex is designed to extend or add new functionality to existing contact center infrastructure. You can keep your PSTN voice carrier and existing phone numbers and connect them to your Flex instance, or integrate with your on-premises systems while using Flex’s cloud-based UI, cross-channel communication flows, and AI assistance.



You can read our Strategies for Migrating an Existing Contact Center to Twilio Flex.

You can deploy a basic Flex instance with minimal coding using our visual editor, Twilio Studio. However, to customize UI components, routing logic, plugins, themes, and integrations you generally need developer resources that can work with JavaScript/React and APIs.

Yes. Flex supports multiple channels (voice, SMS, chat, WhatsApp, web chat) and agents can seamlessly switch between tasks on different channels from a single UI dashboard. You can get an idea of what it looks like in this demo.

Flex lets you turn one-way messages (like product offers or nurture messages) into two-way conversations with an agent. Embed click-to-call or click-to-message entry points in your communications so prospects can reach out to live agents. With Flex, agents can then pull customer profiles in real-time to personalize the interactions, boost conversion, and build loyalty. Flex also integrates with lead management systems like Salesforce to create a single source of truth for agents.

Flex Insights offers dashboards and custom views for KPIs such as handle time, abandoned tasks, queue volumes, and wait times. Supervisors can also drill from high level down into conversation segments, set alerts, and analyze agent performance to keep track of performance.

Everything in Flex is customizable, including the routing logic. With TaskRouter, you can set up flows tailored to your exact set up. You can assign tasks (calls, chats, messages) to agents based on skills, availability, attributes, and escalation/fallback rules. 

See an overview of how TaskRouter works.

Yes. The backend services remain hosted by Twilio, but you have the option to host the Flex UI frontend on your own infrastructure if needed.
