Twilio attach statusCallbackEvent and url on an incoming call - twilio

Question

I am trying to forward a call to user phone if his twilio phone is called.
$usr_ph = 'xxxxxxxxxx'; // get user personal phone from database
$twiml = new Twiml();
$twiml->dial($usr_ph);
return $twiml;
The above code works fine , I need to get the call minutes. So I added status callback url to dial . But its not sending me the any status event
Below is the code I have
$data = array ('statusCallbackEvent' => array('completed'),
statusCallback' => "https://mywebsite.com/get_Call_outcome",
'statusCallbackMethod' => 'POST'
);
$twiml = new Twiml();
$twiml->dial($usr_ph, json_encode($data));
return $twiml;
I did tried :
$twiml = new Twiml();
$twiml->dial($usr_ph, [
'statusCallbackEvent' => array('completed'),
'statusCallback' => "https://mywebsite.com/get_Call_outcome",
'statusCallbackMethod' => 'POST'
]);
return $twiml;
But then I get the error message as
SimpleXMLElement::addAttribute() expects parameter 2 to be string, array given
Not sure , but I think I need to add statusCallbackEvent on the original call which was made on the twilio phone.
Edit:
Now I tried updating the incoming call by adding statusCallbackEvent, but its still not sending any Event.
$twi = new Client($twilio->sid, $twilio->token);
$call = $twi->calls($request->input('CallSid'))
->update(array ('statusCallbackEvent' => array('completed'),
'statusCallback' =>"www.mywebsite.com/get_Call_outcome",
'statusCallbackMethod' => 'POST'
));

Answer 1

The statusCallback is part of the Number noun, not Dial verb. You can find more details below. See if that addresses the issue.

Answer 2

Try this Set Status Codes on Number Noune
$dial->number('[phone]', [
'statusCallbackEvent' => 'initiated ringing answered completed',
'statusCallback' => 'https://myapp.com/calls/events',
'statusCallbackMethod' => 'POST'
]);
