title: "End Call"
description: "Allow your AI agent to terminate calls when conversations reach a natural conclusion or specific conditions are met."
---

The End Call tool enables your AI agent to terminate calls programmatically when conversations reach a natural conclusion, specific conditions are met, or when instructed by the caller.

## How It Works

The End Call tool provides a clean way to terminate conversations:

1. **Agent Decision**: Your AI agent determines the call should end based on conversation context
2. **Optional Message**: Agent can provide a closing message before ending the call
3. **Clean Termination**: Call is terminated gracefully through the telephony provider
4. **Call Disposition**: Call disposition is updated in the system

## Configuration

### Basic Settings

- **End Message**: Optional closing message played before termination
- **Reason**: Optional reason code for call termination tracking

## Agent Usage

Your AI agent can end calls during conversations:

```
end_call(message="Thank you for calling. Have a great day!", reason="conversation_complete")
```

Common scenarios:
- Conversation has reached natural conclusion
- User explicitly requests to end the call
- Agent has completed all requested tasks
- Call timeout or error conditions
