Twilio 调用未更新到 URL 但未引发任何错误

Question

我构建了一个系统，可以进行浏览器到浏览器的调用。

当有来电时，使用接受，他们可以毫无问题地沟通！ twilio 万岁。

所以现在我们有两个人 - 接听电话的人（我们称他们为接听者）和拨打电话的人（我们称他们为拨号器）

然后，接收器有一个按钮 l，称为 Place on Hold。单击此按钮时，它会将接收器重定向到循环消息您有一个呼叫保持，还将拨号器重定向到队列 - 他们会听到一些时髦的音乐。

如果再次点击，接收方拨入队列并获取呼叫方。这也很有效，他们可以再次交流。

但是.....如果我将拨号器放回队列中它可以工作，但是当我通过修改呼叫更新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。

这不会引发错误。就好像 twilio 甚至没有尝试将调用重定向到 URL，因为日志什么也不返回。由于没有错误，我的应用认为一切正常。

发生这种情况有什么原因吗？有限制还是什么？

需要明确的是，这是第一次有效 - 完美。只是不是下一次，只是在检索呼叫时。

这是调用实例上的更新命令的问题。

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);
}

}

这是第二次后没有更新的地方。

$client->calls($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；

1. 保持通话 --> 成功
2. 拨号队列并从队列中获取呼叫者 --> 成功
3. 保持通话 --> 成功
4. 拨号队列并从队列中获取呼叫者 --> FAIL

正如我所说，不会引发任何错误。

我正在使用调用以下 URL 的 Javascript 调用这些

// 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，并且看起来您没有在代码中进行任何序列化，（会话跟踪以防多用户高级用户使用）

退出 OnHold 条件 IE 时是否未清除 PHP 全局变量或其他服务器端变量：在退出前添加代码以清除 PHP

或者换一种说法，就是服务器上的 PHP 变量。它们已设置为 on old 的最后状态。
