### Answer Retell AI captures DTMF (keypad) input from users automatically when enabled in your agent's Call Settings. [(1) ]() Here's how to set it up: Configure DTMF at the Agent Level Go to Call Settings in your agent configuration and enable the following options under **User DTMF Options**: - Digit Limit (

user_dtmf_options.digit_limit

) : Set the maximum number of digits the user can enter (e.g., 10 for phone numbers) - Termination Key (

user_dtmf_options.termination_key

) : Optional key like

#

or

*

that signals the end of input - Timeout (

user_dtmf_options.timeout_ms

) : Time in milliseconds to wait after the last digit before timing out Prompt Your Agent to Request DTMF Input Simply prompt your agent to ask for the information via keypad. For example: "Please enter your PIN number using the keypad. You can finish by pressing the pound key." Access the Captured Input The DTMF input is automatically captured and appears in the call transcript. You can reference it using the variable

{{user_dtmf_input}}

. [(2) ]() [(3) ]() To extract and use it in your conversation flow, add an Extract Dynamic Variable node to store the input in a custom variable (e.g.,

{{phone_number}}

) . Important Note The Press Digit node is designed for agents to navigate IVR systems, not to capture user keypad input. [(2) ]() Use the agent-level DTMF settings described above instead.
