The Get Details of a Live Call API resource will provide information for an active call.
The Get All Live Calls API will provide information about all active calls for a specific account. The API will return the direction of the call, the from and to numbers, the call status, and other information.
To get the status of all calls that are currently in progress, you will need to specify the callback_url, ring_url, or hangup_url. Plivo notifies these URLs of the status of each call: if the call was not answered, or if the call is queued, and etc. The URL must be publicly accessible by Plivo.
