Trying to connect two calls with Twilio using the first call sid to connect to the next call - twilio

Question

I am new to Laravel 9 and usage of Twilio API.
I am trying to create a scenario where a customer_care will call the first participant and after talking with the participant it will call the second participant with whom the first participant will communicate. While calling the second participant, the first participant's call will be kept on hold and after the second participant receives the call both their call will be merged so that they are connected to the same call.
I have written two separate function one for the first call and the other for the second call . The first function is:
public function twiliocall1(Request $request) {
$returnArray = array();
$status = "Error";
$msg = "Call not started";
$validator = Validator::make($request->all(), [
'participants' => 'required|array',
'twilloNo' => 'required',
'contact_id' => 'required'
]);
if ($validator->fails()) {
return response()->json(['error' => $validator->errors()], 401);
}
$twilloNo = $request->input('twilloNo');
$participants = $request->input('participants');
$sid = "xxxxx";
$token = "yyyy";
$client = new Client($sid, $token);
if (!empty($participants)) {
foreach($participants as $participant) {
$call1 = $client->account->calls->create(
$participant,
$twilloNo,
array("url" => "https://lbwr.operative.dev/multitenant/public/files/conference.php")
);
}
$status = "Success";
$msg = "Call started";
echo($call1->sid);
}
$returnArray['status'] = $status;
$returnArray['msg'] = $msg;
return response()->json($returnArray, 200);
}
The second function is:
public function twiliocall2(Request $request) {
$returnArray = array();
$status = "Error";
$msg = "Call not started";
$validator = Validator::make($request->all(), [
'participants' => 'required|array',
'twilloNo' => 'required',
'contact_id' => 'required',
'sid' => 'required'
]);
if ($validator->fails()) {
return response()->json(['error' => $validator->errors()], 401);
}
$twilloNo = $request->input('twilloNo');
$participants = $request->input('participants');
$parent_sid = $request->input('sid');
$sid = "xxxx";
$token = "yyyy";
$client = new Client($sid, $token);
foreach($participants as $participant) {
$call = $client->account->calls->get($parent_sid);
$call->update(
$participant,
$twilloNo,
array(
"Url" => "http://demo.twilio.com/docs/voice.xml",
"Method" => "POST"));
}
$status = "Success";
$msg = "Call started";
$returnArray['status'] = $status;
$returnArray['msg'] = $msg;
return response()->json($returnArray, 200);
}
$sid and $token value is same for both the function. I am trying to call the first function using the following json array:
{
"participants":["12345"],
"twilloNo":"68564",
"contact_id":"1234"
}
And on hitting I am getting the sid of this call which I am passing as a json array element to the function twiliocall2() as:
{
"participants":["+7777"],
"twilloNo":"111122",
"contact_id":"1023",
"sid":"fdthgfjkhbklnj"
}
All the values are changed.
The problem arises when I am calling the second function with this Json array as it throws an error:
Twilio\Exceptions\TwilioException: Unknown subresource get in file /opt/lampp/htdocs/multitenant/vendor/twilio/sdk/src/Twilio/Rest/Api/V2010/Account/CallList.php
Kindly suggest if possible where am I going wrong. I am not getting any idea how to implement this scenario any further.
