"statusCallbackEvent" => array(
"initiated", "ringing", "answered", "completed"

In this example how to get event after call

Answer 1

Your code is correct for registering call status notifications from Twilio. For every event you specified in your statusCallbackEvent array, Twilio will make an asynchronous HTTP request to the URL specified in the statusCallback parameter. See this article for more details.
So now you will need a service at this URL: https://www.myapp.com/events, listening for notification sent by Twilio. In your case these will be POST requests, given the method you specified in statusCallbackMethod parameter. The parameter you need to tell which event is being notified is CallStatus. See this documentation for more info.
We're not using PHP, but if you want to do a quick test, just create a Twilio Function and paste the following code in there to see your event notifications:
exports.handler = function(context, event, callback) {
let response = { get_started: true };
console.log(`Call status notified was '${event.CallStatus}'.`);
callback(null, response);
};
