Sometimes callers prefer to provide information via DTMF (phone keypad presses) rather than speaking — for example, when entering a PIN in a public place. DTMF input from users is captured and included in the agent’s context by default. To use it, simply prompt the agent to ask for the information via keypad. Example prompt:Documentation Index

DTMF Input Completion Options
Configure when the agent considers DTMF input complete. These options are under Call Settings:| Option | API field | Description |
|---|---|---|
| Digit Limit | user_dtmf_options.digit_limit | Maximum digits the user can enter. Input completes when limit is reached. |
| Termination Key | user_dtmf_options.termination_key | A key (#, *, or any digit) that signals end of input. |
| Timeout | user_dtmf_options.timeout_ms | Milliseconds to wait after the last digit before timing out. Resets with each new digit. |
