如何让此代码表示“请按住”并播放自定义的mp3？

Question

这是会议线，开始于主持人加入时。

它完美的作品，除非我不知道如何让它说：“请握住，你很快就会连接。”给所有来电者。

我也想播放保存音乐的自定义mp3文件。

<?php 
// Get the PHP helper library from twilio.com/docs/php/install 

// this line loads the library 
require_once '/var/www/one/conference/twilio/Twilio/autoload.php'; 
use Twilio\Twiml; 

// Update with your own phone number in E.164 format 
$MODERATOR = '[phone]'; 

$response = new Twiml; 

// Start with a <Dial> verb 

$dial = $response->dial(); 

// If the caller is our MODERATOR, then start the conference when they 
// join and end the conference when they leave 
if ($_REQUEST['From'] == $MODERATOR) { 
$dial->conference('My conference', array(
      'startConferenceOnEnter' => True, 
      'endConferenceOnExit' => True, 
      'beep' => True, 
      'record' => True 

      )); 

} else { 
// Otherwise have the caller join as a regular participant 
$dial->conference('My conference', array(
      'startConferenceOnEnter' => False 
      )); 
} 

print $response; 

?>

Twilio开发者传道这里。

为了在通话开始时收到留言，您需要使用TwiML <Say> verb，然后再使用<Dial>。

要在会议开始前播放自定义音乐，您需要在<Conference>标记上使用waitUrl attribute。 waitUrl是指向MP3或Wav文件或返回TwiML的内容的URL，其中可能包含多个<Say>或<Play>动词。

这里是你的代码的更新，其中包括在开始和消息对音乐的waitUrl（值得注意的是，主持人不需要waitUrl，因为他们开始会议）：

// Get the PHP helper library from twilio.com/docs/php/install 

// this line loads the library 
require_once '/var/www/one/conference/twilio/Twilio/autoload.php'; 
use Twilio\Twiml; 

// Update with your own phone number in E.164 format 
$MODERATOR = '[phone]'; 

$response = new Twiml; 

// Start with a welcome message 
$response->say("Please hold, you'll be connected shortly."); 

// Then add the <Dial> verb 
$dial = $response->dial(); 

// If the caller is our MODERATOR, then start the conference when they 
// join and end the conference when they leave 
if ($_REQUEST['From'] == $MODERATOR) { 
$dial->conference('My conference', array(
      'startConferenceOnEnter' => True, 
      'endConferenceOnExit' => True, 
      'beep' => True, 
      'record' => True 
      )); 

} else { 
// Otherwise have the caller join as a regular participant 
$dial->conference('My conference', array(
      'startConferenceOnEnter' => False, 
      'waitUrl' => 'http://twimlets.com/holdmusic?Bucket=com.twilio.music.classical' 
      )); 
} 

print $response; 

让我知道如果这有帮助的话。
