# End call

> Configure the Retell AI agent to end calls automatically based on user-defined conditions.

By default, the agent won't end the call automatically. You'll need to configure when and how the call should be terminated using the end call tool.

<Steps>
  <Step title="Add End Call Tool">
    Click "+ Add" in the tools section and select "End Call" from the dropdown menu.

  <Step title="Update the Prompt">
    Enhance the agent's understanding by incorporating the end call conditions into the prompt. Include specific instructions such as:

    "If the user says 'thank you', 'goodbye', or 'bye', use the end\_call tool to terminate the conversation."
