Outgoing call from Twilio is not working in Laravel 5.5 - php

Question

I'm new to Twilio. I'm using Twilio for phone verification of my app. I'm using Laravel 5.5 for the backend & APIs. I've successfully sent the SMS to phone. I'm getting the call from Twilio but it says an application error. It doesn't read what I want to hear.
Below I'm giving every detail of my code.
Used composer require twilio/sdk for Twilio.
This is my Controller.
use Twilio\Rest\Client;
use Twilio\Twiml;
class AppUserController extends Controller{
private $account_sid;
private $auth_token;
private $twilio_number;
public function __construct(){
$this->account_sid = Config::get('envvalue.account_sid');
$this->auth_token = Config::get('envvalue.auth_token');
$this->twilio_number = Config::get('envvalue.twilio_number');
}
public function reVerification(Request $request){
$client = new Client($this->account_sid, $this->auth_token);
try {
$client->account->calls->create(
$receiverNumber,
$this->twilio_number,
array(
"url" => "http://demo.bitcanny.com/marine-admin/public/api/twiml/"
)
);
return response()->json([
'success' => true,
'statusCode' => '200',
'message' => 'Otp send again'
], 200);
}
catch (Exception $e) {
return $e->getMessage();
}
}
public function twiml(){
// A message for Twilio's TTS engine to repeat
$sayMessage = 'Hello.';
$twiml = new Twiml();
$twiml->say($sayMessage);
$response = Response::make($twiml, 200);
$response->header('Content-Type', 'text/xml');
return $response;
}
}

Answer 1

I found the solution. There's a silly mistake. I didn't use Response in the header of my controller.
use Response;
