This guide provides you brief configuration steps to start to build a text/audio/video chat program using Ozeki VoIP SIP SDK. After configuration, please also check the source code explanation page.

Introduction

Ozeki Silverlight VideoChat sample program demonstrates how to build a text/audio/video chat program using Ozeki VoIP SIP SDK among more Silverlight client applications. The SL clients connect to a server that records the logged in users, and forwards media data arriving from the clients to the appropriate client. After logging into the VideoChat server, the Silverlight client can optionally make and receive audio and video calls, or text messages from the logged in clients.

Creating the project

1. Create a new Solution with a Silverlight 4 application in File->New Project menu and also create a web application that will host the Silverlight application.
   
   
2. Create another Solution that will provide the server implementation for the Silverlight client application in a Console Application form.
   Note: Sometimes VS2010 create projects that are set with .Net Framewrok 3.5 with ".NET 3.5 Client Profile" by default. If this is the case, the project needs to be set to .NET 3.5 in order to boost the full toolkit.
   
   
3. As the next step, the server-side and client-side references of the Ozeki VoIP SIP SDK need to be added to the appropriate project. VoIPSDK.dll is added to the server side, SLClientSDK.dll is added to the Silverlight 4 application. (Please note that this latter reference shouldn't be added to the web application because the Silverlight application will not find the referred references.)

Which Ozeki SDK license you need

The licensing of Ozeki VoIP SIP SDK is based on the numbers of simultaneous calls you can make with it. In this way, you can choose from various licenses according to your needs. If you need only a few simultaneous calls, you can select a lower capacity SDK license. While if you need large numbers of calls at the same time, you can choose a high capacity SDK license.
