Telnyx Launches AI-Powered IVR That Lets Callers Speak Naturally Instead of Pressing Keys

Telnyx has released an open-source Python/Flask application that replaces traditional touch-tone phone menus with a natural language IVR system. Inbound calls are handled using Telnyx Call Control, while an LLM dynamically generates greetings and routes callers to the correct department based on spoken input. Menu configurations are stored per phone number in a key-value store, allowing businesses to update routing options without changing code. If the AI model fails to determine intent, the system falls back to keyword matching, and calls exceeding three turns are automatically transferred to a default operator. The project is publicly available on GitHub and uses Ed25519 webhook signature verification to prevent spoofed requests from triggering unauthorized call actions.
