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