### Recognizing DTMF

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. Start a call via the Interaction Panel by clicking **\> Start Call**, then enter `#`.
