Twilio Voice Api - 是否可以录制消息并在流程中播放录制消息

Question

当接到来电时，我需要要求调用者录制消息。然后调用一个号码，并在接听者接听电话时播放录制的消息。

这可能吗？

Answer 1

注意:将帐户 SID、身份验证 token 、电话号码、网站地址替换为您的值。

第 1 步。

接听来电并记录消息(http://somewebsite.xyz/recordMessage.php)

<?php    
    header("content-type: text/xml");
    echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
?>

<Response>
    <Say>
        Please leave a message at the beep. 
        Press the star key when finished. 
    </Say>
    <Record 
        action="http://somewebsite.xyz/makeOutgoingCall.php" 
        maxLength="60"
        timeout="10"
        finishOnKey="*"
        />
    <Say>I did not receive a recording</Say>
</Response>

录制完成后，Twilio 将向“action”URL 发出请求，并将录制的 URL 作为名为 RecordingUrl 的参数传递($_REQUEST['RecordingUrl'] )

第 2 步。

调用电话 (http://somewebsite.xyz/makeOutgoingCall.php)

<?php
    header("content-type: text/xml");
    echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
?>

<Response>
    <Say>Thank you for your message. Goodbye.</Say>
    <Hangup/>
</Response>

<?php
    // Include the Twilio PHP library
    require 'Services/Twilio.php';

    // Twilio REST API version
    $version = "2010-04-01";

    // Set our Account SID and AuthToken
    $sid = 'AC123';
    $token = 'abcd';

    // A phone number you have previously validated with Twilio
    $phonenumber = '4151234567';

    $recordingUrl = urlencode($_REQUEST['RecordingUrl']);

    // The URL Twilio will request when the call is answered            
    $twilioRequestUrl = "http://somewebsite.xyz/playRecordedMessage.php?RecordingUrl=".$recordingUrl;

    // Instantiate a new Twilio Rest Client
    $client = new Services_Twilio($sid, $token, $version);

    try {

        // Initiate a new outbound call
        $call = $client->account->calls->create(
            $phonenumber, // The number of the phone initiating the call
            '5101234567', // The number of the phone receiving call
            $twilioRequestUrl 
        );
        //echo 'Started call: ' . $call->sid;
    } catch (Exception $e) {
        //echo 'Error: ' . $e->getMessage();
    }

第 3 步。

播放录制的消息 (http://somewebsite.xyz/playRecordedMessage.php)。

<?php

    // and play the recording back, using the URL that Twilio posted
    header("content-type: text/xml");
    echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
?>
<Response>
    <Say>Take a listen to your message.</Say>
    <Play><?php echo $_REQUEST['RecordingUrl']; ?></Play>
    <Say>Goodbye.</Say>
</Response>
