For achieving this solution, you can download and install Ozeki VoIP SIP SDK on your computer to speed up your work. You will also need to have Visual Studio 2010 or compatible IDE and .NET Framework installed on your system, as the server program code below is written in C# language. You also need to have Adobe Flash Builder in order to implement the client-side application as it is in Flash language.

The aim of this article is to show you how you can create a Facebook application from a Flash video phone solution that can call another Flash video phone. This goal will be achieved by having a C# server running at a public address. For the client side the webphone will be set as a Canvas application.

To get more information on how to create a Canvas application from your webphone, you can find a detailed guide at Facebook to SIP calls page.

You can also define a web application on Facebook, in that case you can use the knowledge of building a web page with your webphone solution you can find on the Adding a Flash softphone to a web application page.

If you want to make sure your webphone will work properly, you need to set the right address information of the webphone server and have to make sure that the server runs when you use the webphone.

With this method you can also place a web conference or even a more difficult webphone solution in a Facebook application. You only need to make sure that the server is running at a public IP and the clients can reach it.
