Retrieve the current status of an outbound call, using the call_sid returned when the call was placed. Poll this endpoint until the status reaches a terminal value — success or failure.

Call statuses

Status	Description
`queued`	The call has been accepted and is queued for dialing.
`calling`	PolyAI is dialing the destination number.
`success`	The call connected and completed successfully.
`failure`	The call did not connect or ended in an error.

The optional reason field gives extra detail for the status.

Call statuses are retained for roughly 2 hours after the call is placed. After that the call_sid is no longer queryable and the endpoint returns 404.
