### Answer Yes, Retell AI supports capturing caller keypad input through the *Listen to User Keypad Input (DTMF Capture) * feature [(1) ]() . This feature allows callers to enter numbers using their keypad, which improves accuracy when collecting information like card numbers or phone numbers, especially in noisy environments where speech recognition might struggle . How it works: - Set your AI agent to prompt users to enter digits (e.g., card number, phone number) - The system captures input directly from the keypad, eliminating transcription errors - Use post-call analysis to store and process the data as needed You can configure different input-ending methods: - **End with a special key**: Let users press # or * to finish entering input (useful for variable-length information like ID numbers) - **Fixed digit length**: Automatically end input after a specific number of digits (perfect for fixed fields like the last 4 digits of an SSN) - **Timeout-based ending**: If no input is received after a short period, input collection will end automatically (enabled by default) For more details, check out the [documentation on DTMF input]() .
