ScreenCall进程不连接呼叫

Question

我有一个用户呼叫我的Twilio号码，然后Twilio尝试连接呼叫者与代理的用例。当代理人＃拿起我使用ScreenCall过程，以确保它是一个人，他们必须按数字。问题是，只要进入ScreenCall过程，一切都在代理端工作，但是当他们按下一个数字时，调用者就不会连接到它们。

我错过了什么？只要代理人应答，我一旦删除屏幕呼叫，呼叫者和座席就会立即连接。

public ActionResult CallAgents(string From, string To, string CallSid) 
    { 
     var response = "<Response><Dial action = '" + Url.Action("EndCall", "Call") + "'> 
<Number action = '" + Url.Action("ScreenCall", "Call") + "'>1231231234</Number></Dial></Response>"; 

     return new TwiMLResult(response); 
    } 

public ActionResult ScreenCall(string From, string To, string CallSid) 
    { 
     var response = new TwilioResponse(); 

     response.BeginGather(new { action = "AnswerCall", numDigits = 1 }) 
      .Say("Press any key to accept the call.") 
      .EndGather(); 


     return new TwiMLResult(response); 
    } 

public ActionResult AnswerCall(string From, string To, string CallSid) 
    { 
     var response = new TwilioResponse().Say("Thank you, you are now being connected.").Record(); 

     return new TwiMLResult(response); 
    } 

Answer 1

response.BeginGather（新{行动= “AnswerCall” numDigits = 1}）

在上述AnswerCall似乎仅仅是一个字符串。 <Gather>的action attribute需要绝对或相对URL作为值。当代理完成输入数字时，Twilio将向此URL发出GET或POST请求。提出此请求后，Twilio将使用您在回复中收到的TwiML继续当前的呼叫。

的片段有当代理筛选通话看起来是这样的：

// POST: Agent/ScreenCall 
[HttpPost] 
public ActionResult ScreenCall(string from) 
{ 
    var response = new TwilioResponse(); 
    var incomingCallMessage = "You have an incoming call from: " + 
           SpelledPhoneNumber(from); 
    response.BeginGather(new {numDigits = 1, action = Url.Action("ConnectMessage")}) 
     .Say(incomingCallMessage) 
     .Say("Press any key to accept") 
     .EndGather(); 

    response.Say("Sorry. Did not get your response"); 
    response.Hangup(); 

    return TwiML(response); 
} 

// GET: Agent/ConnectMessage 
public ActionResult ConnectMessage() 
{ 
    return TwiML(new TwilioResponse() 
     .Say("Connecting you now...")); 
}
