构建SIP应用程序 [英] Building SIP Application

问题描述

大家好，

我想使用.NET开发一个应用程序，使用户可以在线学习.我打算使用SIP来实现我们的系统，但是我不知道从哪里开始.我需要同时编写SIP服务器和用户代理，还是只编写UA并使用任何SIP服务器.

我尝试使用OfficeSIP服务器和OfficeSIP消息( http://www.officesip.com/)，并且想将其用于自己的应用程序.但是，我发现他们使用的是Microsoft统一通信客户端SDK中包含的UccApi.dll，而且我听说用此SDL构建的SIP客户端只能与Microsoft Communication Server一起使用.是吗?

我真的不知道从哪里开始.请帮帮我.

在此先谢谢您. )基于电话的C# [ ^ 来自Codeproject的]会给您和Idea.

非常感谢Kasson.真的有帮助.再次感谢！

您好，

现在我知道从哪里开始，但是我面临另一个困难.我发现多播是实现视频会议的理想选择，因为它减少了网络负载.人们谈论多播.在有关视频会议的任何文档和文章中，他们都建议使用多播.但是，我找不到一种使多播可以通过Internet工作的方法.

在使用Google数天后，我发现无法在Internet上使用多播，因为网络路由器不支持多播.为了使其正常工作，我需要加入一些虚拟网络，例如Mbone.但是，加入它需要很多时间，并且软件无法做到这一点.用户需要与他们的ISP联系以寻求帮助，我不能强迫使用我的应用程序的每个用户都加入Mbone网络.

那么多播只是一个实验吗?反正有什么解决方法吗?

请帮帮我！

Hi everyone,

I want to develop an application using .NET which enable users to study online. I intent to use SIP to implement our system but I don''t know where to start. Do I need to write both SIP server and user agent or just write my UA and use any SIP server.

I tried OfficeSIP server and OfficeSIP Message (http://www.officesip.com/) and I want to use it for my own application. However, I found out that they use UccApi.dll which is included in unified communication client SDK of Microsoft and I heard that SIP cliend built with this SDL can only be used with Microsoft Communication Server. Is that right?

I really do not know where to start. Please help me out.

Thanks in advance.

Hope Simple SIP(VOIP) based phone in C#[^]from Codeproject will give you and Idea.

Thanks you very much Kasson. It really help. Thanks again!

Hi,

Now I know where to start but I am facing another difficulty. I found that multicast is ideal for implementing video conference because it reduces network load. People say about multicast a lot. In any document and article about video conference, they recommend multicast. However, I cannot find a way to make multicast work over the internet.

After Google it for days, I found out that multicast cannot be used over the internet because the network router does not support multicast. In order to make it work, I need to join to some virtual networks like Mbone. However, joining it take a lot of time and it is not a thing software can do. Users need to contact with their ISPs for help and I cannot force every user who using my application to join into the Mbone network.

So is multicast just an experiment? Is there anyway to work around?

Please help me out!
