Telnyx now offers a new Flowchart Editor for Voice AI Assistant workflows in the Mission Control Portal. The click-and-add canvas lets you add, edit, and connect tools in one place, providing a clear view of the entire call flow with detailed control over each step.
The Editor provides a visual way to design and manage your Voice AI Assistant’s workflow. Each workflow appears as a connected diagram of nodes, where the main assistant node links to various tool nodes that define how calls progress.
These nodes control call behavior, including Add Webhook, Add Handoff, Add Transfer, Add SIP Refer, Add Send DTMF, and Configure Handoff, which hands the call off to another AI assistant. After adding a tool, you’ll be prompted to configure its settings, and you can return to the node at any time to review or adjust those settings.
Each added tool appears as a color-coded node within the flowchart, with matching connection lines that illustrate relationships: purple for transfers, red for hang-ups, and blue for other interactions. Simple zoom and pan controls make it easy to explore and review even complex multi-agent AI assistant workflows.
Together, the editor and tools offer an intuitive, interactive way to visualize, build, and refine your Voice AI Assistant’s conversation paths.

The Editor enables visual design of complex call flows, making it easier to automate sophisticated customer interactions. By streamlining routing between voice AI assistants and various tools, it helps deliver faster, more consistent experiences and reduces support workload.
