Could someone tell me if the assistant can recognize when the user types on the phone’s virtual keyboard during a call?

Yes, the assistant can recognize when a user types on their phone’s keypad (virtual or physical) during a call by enabling DTMF keypad input support. To activate this, add the following to your assistant configuration:

json
"keypadInputPlan": {
  "enabled": true,
  "delimiters": ["#"],
  "timeoutSeconds": 2
}

This allows the assistant to collect numeric input from callers during phone calls. For more details, see the [Vapi changelog](https://docs.vapi.ai/changelog/2025/2/27). Source: - [Phone Keypad Input Support, OAuth2 and Analytics Improvements](https://docs.vapi.ai/changelog/2025/2/27)
