# Reject Call

| Step Details |
| --- |
| **Introduced in Version** | 4.0.0 |
| **Last Modified in Version** | 8.9.0 |
| **Location** | Integration > Twilio > Phone |

The **Reject Call** step rejects an inbound call, and plays a recording to the rejected caller. The recording is sourced from either a URL, a document, or a text. There is also an option to play nothing to the caller. The call may be rejected as busy, which then plays the Twilio busy signal to the caller. This step is very useful in preventing unwanted calls, and prevents Twilio from billing the call to an account's Twilio number.

### Prerequisites

- This step requires the [Telephony Module](https://documentation.decisions.com/docs/telephony) to be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) before it will be available in the toolbox.
- **For v9 users:** Add a [Project Dependency](https://documentation.decisions.com/docs/project-dependencies) once the Telephony Module is installed.
