Hi all,
If you need advanced webphone applications eg: video phoning on your website using Silverlight, you can check this site
http://www.voip-sip-sdk.com/p_85-web...ight-voip.html. This sample program is developed by Ozeki VoIP SIP SDK and they also provide explanation for configuration and source code.
And they have a helpful support team as well. :)
