如何使用Twilio，而不是只播放MP3时，呼叫接通，使真人语音电话？ [英] How to make live voice phone call using Twilio instead of just playing an MP3 when call is answered?
问题描述
要通过Twilio呼叫从笔记本电脑的电话号码，我创建的ASP.NET MVC 5.2应用程序。
我可以拨打一个号码，接电话，但我不知道该如何实现真人语音（要能讲）连接，而不仅仅是播放音乐。
我创建了内部的操作方法的HomeController ：
公众的ActionResult调用（字符串）{
客户端=新TwilioRestClient（Settings.AccountSid，Settings.AuthToken）; VAR的结果= client.InitiateOutboundCall（Settings.TwilioNumber，以http://twimlets.com/message?Message%5B0%5D=http://demo.kevinwhinnery.com/audio/zelda.mp3）; //它会导致玩塞尔达主题时调用是由被叫方回答 如果（result.RestException！= NULL）{
返回新System.Web.Mvc.HttpStatus codeResult（500，result.RestException.Message）;
} 返回的内容（叫途中！）;
} 公众的ActionResult指数（）{
返回查看（）;
}
此操作的方法是通过调用Ajax调用。
当我打从视图\\首页\\ Index.csthml 按钮：
＆LT;形式为GT;
＆LT; P＆GT;输入您的手机号码：其中; / P＆GT;
＆LT;输入ID =到类型=文本
占位=恩：16518675309/＆GT;
＆LT;按钮和GT;给我一个消息＆LT; /按钮＆GT;
＆LT; /表及GT;
下面的脚本调用从＆LT传递的电话号码;输入ID =到＆GT; 来操作方法公众的ActionResult呼叫（串）在的HomeController ：
$（'形式的按钮'）。在（'点击'，功能（E）{
亦即preventDefault（）; //想到刚文本字符串从服务器返回
VAR URL ='/呼叫';
$就（URL，{//调用调用操作方法
方法：POST，
数据类型：'文字'，
数据：{
于：$（'＃为）VAL（）//经过数参数的操作方法
}，
成功：功能（数据）{
showFlash（数据）;
}，
错误：功能（jqxhr）{
警报（'发生错误发送到服务器的请求'）;
}
}）
}）;
这开始打电话给指定的号码，即 48123456789 ，其中 48 是该国code。当呼叫由被叫方回答，塞尔达主题播放。（的http://twimlets.com/message?Message%5B0%5D=http://demo.kevinwhinnery.com/audio/zelda.mp3 ）
相反的，我想通过笔记本谈论（它有内置麦克风），以我打过电话的人，让这个人顶嘴。在几句话我想有真人语音。
问：如何实现ASP.NET MVC的5.x的使用Twilio真人语音电话
Settings.AccountSid 和 Settings.AuthToken 是我的凭据：
公共静态类设置
{
公共静态字符串AccountSid {{返回A ############### 0; }}
公共静态字符串的authToken {{返回E ############### 0; }}
公共静态字符串TwilioNumber {{返回4 ######## 1; }}
}
Twilio传道这里。
如果要放置在浏览器中一个电话你需要看看使用Twilio客户端JavaScript的：

这将让您可以从浏览器到Twilio VoIP呼叫。一旦呼叫Twilio可以再桥梁与另一个Twilio客户端，SIP终端或PSTN电话拨打：

希望有所帮助。
To call phone number from notebook through Twilio I created ASP.NET-MVC 5.2 application.
I can call a number and answer the phone but I don't know how to achieve live voice(to be able to talk) connection instead of just playing music.
I created an action method inside HomeController:
public ActionResult Call(string to) {
client = new TwilioRestClient(Settings.AccountSid, Settings.AuthToken);
var result = client.InitiateOutboundCall(Settings.TwilioNumber, to, "http://twimlets.com/message?Message%5B0%5D=http://demo.kevinwhinnery.com/audio/zelda.mp3"); //it causes to play zelda theme when call is answered by callee
if (result.RestException != null) {
return new System.Web.Mvc.HttpStatusCodeResult(500, result.RestException.Message);
}
return Content("Call enroute!");
}
public ActionResult Index() {
return View();
}
This action method is invoked by Ajax call.
When I hit the button from Views\Home\Index.csthml:
<form>
<p>Enter your mobile phone number:</p>
<input id="to" type="text"
placeholder="ex: +16518675309" />
<button>Send me a message</button>
</form>
The script below is invoked which passes the phone number from <input id="to"> to the action method public ActionResult Call(string to) in the HomeController:
$('form button').on('click', function(e) {
e.preventDefault();
// expect just a string of text back from the server
var url = '/call';
$.ajax(url, { //invokes call action method
method:'POST',
dataType:'text',
data:{
to:$('#to').val()//passes the number argument to the action method
},
success: function(data) {
showFlash(data);
},
error: function(jqxhr) {
alert('There was an error sending a request to the server');
}
})
});
This starts phone call to the specified number i.e. 48123456789 where 48 is the country code. When the call is answered by the callee, the zelda theme is played.( http://twimlets.com/message?Message%5B0%5D=http://demo.kevinwhinnery.com/audio/zelda.mp3 )
Instead of that I would like to talk through notebook(it has internal microphone) to the person I've called and let this person talk back. In few words I would like to have live voice.
Question: How to achieve live voice phone call using Twilio in ASP.NET-MVC 5.x?
Settings.AccountSid and Settings.AuthToken are my credentials:
public static class Settings
{
public static string AccountSid { get { return "A###############0"; } }
public static string AuthToken { get { return "e###############0"; } }
public static string TwilioNumber { get { return "4########1"; } }
}

If you want to place a phone call from your browser you'll need to look at using Twilio Client for JavaScript:
https://www.twilio.com/docs/quickstart/csharp/client
That will let you place a VoIP call from the browser into Twilio. Once the call reaches Twilio you can then bridge that call with another Twilio Client, SIP endpoint or PSTN phone:

Hope that helps.
