Twilio TaskRouter: Unable to connect Reservation to Call

I am using TaskRouter Twilio with Laravel.

Here is what I am doing right now

1. I have attached a twiml app to a phone number.

2. Added a webhook to that twiml app.

3. On that webhook I am hitting this code $response = new VoiceResponse();

   $taskAttributes = [
       'channel' => 'voice', // Specify that it's a voice call
   
   ];
   
   $enqueue = $response->enqueue('WSDSupport',['workflowSid' => $workflowSid,
                                               'action' => url('ivr/testQueue')]);
   $enqueue->task(json_encode($taskAttributes),['timeout' => 200]);
   return response($response)->header('Content-Type', 'text/xml');
   

4. Now on frontend I received the reservation created event (reservation.created)

5. I get a prompt to accept the reservation. When I do.

   if (confirm('Incoming call. Accept?')) {
                          reservation.accept();
                      } else {
                          reservation.reject();
                      }
   

Worker is selected but nothing happens. On the Workflow callback URL I am running this code.

 return response()->json([
                 "instruction"=> "dequeue",
                 "from"=> $taskAttributes['from'],
                 "post_work_activity_sid"=> config('services.twilio')['postWorkActivitySid']
             ]);

I need to connect my agent via a call to the customer. I have searched everwhere but did not find any help.

I figured it out

return response()->json([
            "instruction"=> "dequeue"
        ]);

Just return this. This will look for the worker who has accepted the reservation and call that worker contact_uri,

contact_uri: '' // This can be the client id which you have used to created the token on client side.

which is set in his/her profile on Twilio. It can be a phone number or browser client id.
