How to enable DTMF Events in Telephony AI Agent
Blog post from Video SDK
DTMF (Dual-Tone Multi-Frequency) input is an effective method for managing interactions in voice agent systems, especially when speech recognition may be unreliable, allowing users to make selections, confirm actions, and navigate call flows by pressing phone keys. This capability is particularly useful in menu-based systems and for short responses, providing a predictable and clear way for voice agents to handle user input. The integration of DTMF events in VideoSDK-powered voice agents enables real-time processing of keypad inputs to control call flows or trigger specific application logic. By enabling DTMF detection through either a dashboard or an API, developers can create structured and efficient call experiences. The implementation of DTMF complements voice input, offering enhanced control over user interactions and making it a valuable addition to voice agents that require deterministic user inputs.
