Question

我有一个系统，可以进行浏览器到浏览器的调用。

当来电时，使用接受，他们可以毫无问题地进行通信！ Hooray for twilio。

所以现在我们有两个人 - 接听电话的人（让我们称他们为接收者）和打电话的人（让他们称之为拨号器）

然后接收器有一个叫做保持状态的按钮。单击此按钮时，它会将接收器重定向到您保持呼叫的循环消息，并将拨号器重定向到队列 - 他们可以收听一些时髦的音乐。

如果再次单击它，Receiver将拨打队列并获取呼叫者。这也很有效，他们可以再次沟通。

但是.....如果我把拨号器放回队列中就行了，但是当我通过修改Calls update方法检索它并将其重定向到与呼叫未更新之前相同的部分时。 / p>

这不会引发任何错误。这几乎就像twilio甚至没有尝试将调用重定向到URL，因为日志没有返回任何内容。由于没有错误，我的应用程序认为一切正常。

这是否会发生这种情况？有限制吗？

要清楚这是第一次工作 - 完美。只是不是下一次，只有在检索电话时。

这是Call实例上的update命令的问题。

我使用Laravel作为我的框架

这是我的Routes.php

// Hold music and Client Message 
Route::post('voice/queue/music', ['uses' => 'API\VoiceController@queueHoldMusic']);
Route::post('voice/queue/client-message', ['uses' => 'API\VoiceController@clientHoldMusic']);

// Routes containing Twiml XML
Route::post('voice/inbound/enqueue-call', ['uses' => 'API\Voice\InboundCallHoldController@placeInboundCallOnHold']);
Route::post('voice/inbound/dequeue-call', ['uses' => 'API\Voice\InboundCallHoldController@dialHeldInboundCall']);

// Place Outbound Call on Hold
Route::post('inbound/enqueue', ['uses' => 'API\Voice\InboundCallHoldController@holdInboundCall']);
Route::post('inbound/dequeue', ['uses' => 'API\Voice\InboundCallHoldController@getInboundCallOnHold']);

这是我的InboundCallHoldController.php

class InboundCallHoldController extends Controller
{

public function placeInboundCallOnHold(Request $request){
    $CallSid = $request['CallSid'] !== null ? $request['CallSid'] : null;
    $response = new Twiml();
    $queue = 'call-hold:'.$CallSid;

    Log::info("---> Inbound Call | placeInboundCallOnHold --> Enqueuing Caller ".$CallSid." to ".$queue);

    $response->enqueue($queue, ['waitUrl' => env("API_URL").'/api/voice/queue/music']);
    return response($response)->header('Content-Type', 'text/xml');
}

public function dialHeldInboundCall(Request $request){
    $callSid = $request['ParentCallSid'] !== null ? $request['ParentCallSid'] : null;
    $response = new Twiml();
    $dial = $response->dial();

    $queueName = 'call-hold:'.$callSid;

    Log::info("---> Inbound Call | dialHeldInboundCall --> Dialing a queue to get a caller  ".$queueName);

    $dial->queue($queueName);
    $response->redirect(env('API_URL')."/api/voice/queue/client-message");
    return response($response)->header('Content-Type', 'text/xml');
}

public function getInboundCallOnHold(Request $request){
    $callSid = $request['CallSid'] !== null ? $request['CallSid'] : null;

    $account = Account::where("twilio_sid", "TWILIO_ACCOUNT_SID")->first();
    $client = new Client($account->twilio_sid, $account->twilio_auth_token);

    Log::info("---> Inbound Call | getInboundCallOnHold --> Updating Live call and redirecting Caller ".$callSid . " to Queue");
    $call = $client->calls($callSid)->fetch();

    $client->calls($call->sid)->update([
        "url" => env('API_URL')."/api/voice/inbound/dequeue-call",
        "method" => "POST"
    ]);

    Log::info("---> Inbound Call | getInboundCallOnHold --> ".$callSid . " status is now ".$call->status);

    return response([
        "status" => "fetched-inbound-call",
        "success" => true
    ], 200);

}

public function holdInboundCall(Request $request){
    $callSid = $request['CallSid'] !== null ? $request['CallSid'] : null;

    $account = Account::where("twilio_sid", "TWILIO_ACCOUNT_SID")->first();
    $client = new Client($account->twilio_sid, $account->twilio_auth_token);


    Log::info("---> Inbound Call | Hold Initiated");

    $call = $client->calls($callSid)->fetch();
    $parentCall = $client->calls($call->parentCallSid)->fetch();

        if($parentCall->status === "in-progress" and  $call->status == "in-progress"){
            // find the child - this is the receiver - Play the hold music

            Log::info("---> Inbound Call | holdInboundCall --> Redirect Receiver ".$call->sid . " to wait message");

            $call->update([
                "url" => env('API_URL')."/api/voice/queue/client-message",
                "method" => "POST"
            ]);
            // find the parent - this is the inbound caller - Add them to a queue
            Log::info("---> Inbound Call | holdInboundCall --> Redirect Inbound Caller ".$parentCall->sid . " to queue");
            $parentCall->update([
                "url" => env('API_URL')."/api/voice/inbound/enqueue-call",
                "method" => "POST"
            ]);

            return response([
                "status" => "on-hold-inbound",
                "success" => true
            ], 200);
    }


    return response()->json(["call_hold_failed" => ["A call not be placed on hold until it has been answered"]], 422);
}

}

这是第二次更新后没有发生的情况。

$client->calls($call->sid)->update([
    "url" => env('API_URL')."/api/voice/inbound/dequeue-call",
    "method" => "POST"
]);

这很奇怪，因为这是失败之前的过程;

暂停通话 - ＆gt;的 SUCCESS
拨号队列并从队列中获取来电者 - ＆gt;的 SUCCESS
暂停通话 - ＆gt;的 SUCCESS
拨号队列并从队列中获取来电者 - ＆gt;的 FAIL

正如我所说，没有错误被抛出。

我使用Javascript调用以下网址

// Place Outbound Call on Hold
Route::post('inbound/enqueue', ['uses' => 'API\Voice\InboundCallHoldController@holdInboundCall']);
Route::post('inbound/dequeue', ['uses' => 'API\Voice\InboundCallHoldController@getInboundCallOnHold']);

这是输出的日志;

Answer 1

由于OnHoldStatus是通过PHP设置的，并且它看起来不像你在代码中进行任何序列化，（在多用户高级用户中使用的会话跟踪）

退出OnHold条件IE时，是否会清除PHP全局或其他服务器端变量：在退出之前添加代码以清除PHP

或者说另一种方式是服务器上的PHP变量。它们已经设置为旧的最后状态。

Twilio呼叫不更新到URL但不抛出任何错误
