使用 TWILIO 发起出站呼叫 [英] Initiating Outbound Calls with TWILIO

问题描述

我有一个使用 TWILIO API 的 C# 服务，目前我在尝试使用 InitiateOutboundCalls 函数时遇到了问题.

I have a C# Service using TWILIO API and I am having issues at the moment trying to use the InitiateOutboundCalls function.

private void SendCall(string cellNumber, string message) {
            Call callResult;
            callResult = _client.InitiateOutboundCall(twilioNumber, employeeNumber, message);                
            TwilioRestExceptionCheck(callResult);            
        }

这是 C# 服务中的小函数，它应该用这个 twimlbin 代码(如上的消息变量)调用员工:

This is the little function in the C# Service which is supposed to call the employee with this twimlbin code (the message variable as above):

<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say>Cams Support. See text for Recording</Say>
<Sms>Sending Recording... </Sms>
<Hangup/>
</Response>

问题是，即使员工没有接听电话，即:没有接听他/她的电话，呼叫状态仍然设​​置为完成".呼叫不应该设置为无应答"吗?如何判断员工是接听电话还是未接电话?

The issue is that even if the employee misses the call, ie: doesn't answer his/her phone, the call status is still set as "complete". Shouldn't the call be set as "no-answer"? How can I tell if the employee picks up or misses the call?

谢谢

当员工未接电话时，可能会发生的情况是电话转到应答机，应答机实际上会返回您所看到的完成"状态.

What is likely happening when an employee misses a call is that the call goes to an answering machine which will actually return the "complete" status that you are seeing.

您可能会处理此问题的一种方法是使用 <Gather> 动词确保实际接听电话的是员工，而不是他们的语音邮件.

One way that you might deal with this is to make sure that a call is actually answered by the human employee and not their voicemail using the <Gather> verb.

<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Gather action="/complete_call.xml" method="get">
    <Say>Press any key to accept the call.</Say>
  </Gather>
</Response>

其中 /complete_call.xml 可能如下所示:

Where /complete_call.xml might look like:

<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say>Connecting</Say>
</Response>

您可以阅读有关将这种方法用于 Call Screening 的更多信息，并查看一些 C# 示例那里.

You can read more about using this method for Call Screening and see some C# examples there.
