当我们使用rest api拨打电话时，我们在该url参数上使用了什么twiml [英] when we make call using rest api then what twiml we use on that url parameter

问题描述

我正在使用其余api创建呼叫-

I am Creating the call using the rest api-

try{
        // Initiate a new outbound call
        $call = $this->client->calls->create(

            // to call.
            "num2",

            // Step 5: Change the 'From' number below to be a valid Twilio number 
            // that you've purchased or verified with Twilio.
            "num1",


            array("url" => "url-tw",
            'IfMachine'=>'Continue')

        );
        echo "Started call: " . $call->sid;
    } catch(Exception $e){
        echo "Error: " . $e->getMessage();
    }

在url-tw上应该使用什么twiml不能断开呼叫.

and on the url-tw what twiml should I use which can't disconnect the call.

在使用TwiML处理呼叫之前，但现在我必须检测到AnsweredBy选项，该选项仅在使用REST API进行呼叫时才可用.

Before I was handling the call using the TwiML but now I have to detect the AnsweredBy option which is only available if I make the call using the REST API so.

我使用的是我以前使用twiML拨打电话时使用过的相同twiml，例如使用<Dial>可以再次拨打电话，但是如果我不使用任何twiml，它将断开通话.我错了.

for now I m using the same twiml I have used before when I was making calls using the twiML like use the <Dial> which let to dial again but if I dont use any twiml it disconnect the call.So any advice where I m going wrong.

推荐答案

此处是Twilio的传播者.

Twilio evangelist here.

url参数的值应该是可公开访问的URL，该URL返回 TwiML 包含您希望Twilio对调用方执行的指令.

The value of the url parameter should be a publicly accessible URL that returns TwiML containing the instructions that you want Twilio to execute to the caller.

您的PHP开始调用的样子:

Your PHP to start the call would look like:

// Initiate a new outbound call
$call = $this->client->calls->create(
    "num2",
    "num1",
    array("url" => "http://example.com/answer.php", 'IfMachine'=>'Continue')
);

然后在answer.php中，您可以做两件事:

Then in answer.php, you can do two things:

1. 检查 AnsweredBy 参数以查看Twilio是否检测到机器或人.
2. 根据该值生成您要返回的Twiml

例如，要说与机器对人类不同的东西，您可以在PHP中执行以下操作:

For example to say something different to a machine v a human, you could do something like this in your PHP:

<?php
    header("content-type: text/xml");
    echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
?>
<?php if ($_REQUEST['AnsweredBy']=='machine'): ?>
    <Response>
        <Say>Hello machine</Say>
    </Response>
<?php else: ?>
    <Response>
        <Dial>[phone]</Dial>
    </Response>
<?php endif ?>
