Can I check the source of a specific call using the agent?

Yes! Use the `get_call_details` tool with the Call ID. Your agent will fetch the detailed metadata, which typically includes the `source` or `tracking_number` associated with the call.

How do I list all the leads from my website forms?

Simply ask the agent to `list_form_submissions`. It will retrieve the latest leads captured through web forms from your CallRail account, including names and submission times.

Does the integration allow creating a new tracking number?

The current toolset focuses on querying and monitoring (Read-Only) for marketing attribution analysis. Provisioning new numbers or changing core routing should be managed via the CallRail administrator dashboard.
