Can I send an SMS using the agent?

Yes! Use the `send_sms` tool with the recipient's phone number and your message content. Your agent will trigger the dispatch through CallFire instantly.

How do I check the status of a specific call?

Simply ask the agent to `get_call_details` and provide the Call ID. It will retrieve the latest status, such as 'finished' or 'failed', directly from CallFire.

Does the integration allow creating a new voice broadcast?

The current toolset is focused on individual actions and querying (Read-Only/Individual Dispatch) for operational control. Massive broadcasts should be configured via the CallFire web dashboard.
