How to get the status of the ongoing outbound call (polling)?

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);
