# RECOGNIZED_DTMF

> This event triggers when DTMF keypad input is detected during a call.

The DTMF code was recognized by the AI Agent.

To test a payload with the `RECOGNIZED_DTMF` event, you can use a Flow with only one **Set Session Config** Node.

Input: Add the **Set Session Config** Node to the Flow editor and enable the **Capture DTMF Signals** setting in the Node.
