# Inbound Dial

This webhook is triggered when an inbound dial is made to a phone number linked to an agent. Elto will automatically run the agent after this webhook is triggered.
If the agent is configured with the inbound webhook response option, you may return a JSON object to fill in any parameters in the agent's prompt with the following typescript schema:

```typescript theme={null}
{
    call_agent_input: {
        [key: string]: string;
    };
    keywords: string[];
}
```

However, in this case you'll only have 3 seconds to respond before the call proceeds without the parameters filled in.
