# Gather User Input via Keypad (DTMF Tones)

In this guide, we'll show you how to gather user input during a phone call through the phone's keypad (using [DTMF tones](/docs/glossary/what-is-dtmf)) in your application. By using the [TwiML \<Gather> Verb](/docs/voice/twiml/gather), you can create interactive voice response ([IVR](/docs/glossary/what-is-ivr)) systems and other phone-based interfaces for your users.
