# End Call

> Configure your agent to automatically terminate calls based on conversation conditions.

## Overview

By default, agents do not automatically end calls. You must configure explicit conditions that tell the agent when to hang up.

***

## Setup

<Steps>
  <Step title="Add the tool">
    In your agent's Functions section, select **End Call** from the dropdown.
  </Step>

  <Step title="Set termination conditions">
    Define the triggers that should end the call. Be specific so the agent doesn't hang up prematurely.

    ```txt theme={null}
    If the user says "thank you", "goodbye", or "bye", use the end_call tool to terminate the conversation.
    ```
  </Step>

  <Step title="Add to your prompt">
    Include the end call instructions directly in your agent's prompt so it understands when and how to use the tool.
  </Step>
</Steps>

<Warning>
  Without explicit configuration, your agent will not hang up — the call will stay open until the caller disconnects.
