如何使用 Nexmo 服务制作语音通话网络应用程序？

Question

I have been trying to make an asp.net web application which has the ability to call people on their cellphones etc. I have to use Nexmo API for the calling purpose. Currently, I have implemented samples available on its website for eg. https://github.com/nexmo-community/nexmo-dotnet-quickstart/blob/ASPNET/NexmoDotNetQuickStarts/Controllers/VoiceController.cs

But none of the samples show how to make a call from a browser to lets say a cell phone number. I might be following the wrong links here. Any help will be greatly appreciated here. Edit: Below is the sample I have tried.

[HttpPost]
[Route("voice/event")]
public string Event([FromBody] dynamic type)
{
    return "Event received";
}

[HttpPost]
[Route("voice/call")]
public string MakeCall([FromUri] string to)
{
    var TO_NUMBER = to;
    var NEXMO_NUMBER = "MyNexmoNumber";

    var results = Client.Call.Do(new Call.CallCommand
    {
        to = new[]
        {
            new Call.Endpoint {
                type = "phone",
                number = TO_NUMBER
            }
        },
        from = new Call.Endpoint
        {
            type = "phone",
            number = NEXMO_NUMBER
        },
        answer_url = new[]
        {
            "https://developer.nexmo.com/ncco/tts.json"
        }
    });

    var callUUID = results.uuid;

    return callUUID;
}

Thanks in advance.

You need to use the Nexmo in-app voice product if you want to make voice calls from browser. Here's a link on how to use this , it's in vue.js but hopefully it will give you a good idea on the approach to follow.
