How do I find my Bandwidth API credentials?

Log in to your [**Bandwidth Dashboard**](https://dashboard.bandwidth.com/), navigate to **Account** > **API Credentials** to find your Username and Token. Your Account ID is visible in the URL or the Profile section.

Can the agent check call states?

Yes. Use the `get_call_state` tool providing the Call ID. Your agent will return real-time status such as 'active', 'completed', or 'busy'.

Is it possible to manage conferences via the agent?

Yes. The `list_conferences` tool allows your agent to retrieve all active conferences, helping you monitor multi-party voice sessions in real-time.
