You may want to know the status of a call while it's in progress. Here is an example of how to do that:

function update(next, delay) {

     if (!rcsdk.getRingoutHelper().isInProgress(ringout)) return;

    platform.apiCall(rcsdk.getRingoutHelper().loadRequest(prevRingoutData))

        .then(function(ajax) {

            // also save ajax.data as, for example, prevRingoutData

           console.log(ajax.data); // updated status of ringout

           timeout = next(delay); // you can increase delay here

       })

       .catch(handleError);

}

 var timeout = rcsdk.getUtils().poll(update, 3000); // stay in RPS limits

 To stop polling:

 rcsdk.getUtils().stopPolling(timeout);
