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.
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
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.
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.
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.
When you purchase a license you can easily activate your demo application by
entering the serial number you received from Ozeki after purchase. You can enter
the serial number by opening the Ozeki VoIP SDK License Manager. In
Registration tab you can provide the serial number and click on Activate.
When you decide to purchase Ozeki VoIP SIP SDK license you can select and order the suitable
license at Ozeki VoIP SIP SDK licenses page right
How to activate your Ozeki SIP SDK license?
After you purchased an Ozeki VoIP SIP SDK license
you need to activate it with the serial number. Without activation, you can only use the SDK
in trial mode. You will receive your serial number
from Ozeki right after purchase. The following steps demonstrate how you can
activate the trial version with your serial number:
As the next step, enter your serial number you have received from
Ozeki at Serial number edit box (Figure 2).
Figure 2 - Enter your serial number
Finally, you just need to click on Activation button to
make your license activated. If you enter a valid serial number and the activation
is successful you will receive a notification about this fact (Figure 3).
