Hi! I need to build a SIP webphone with iPhone features. I searched on the net and found a SIP softphone solution with a free sample program: Ozeki C# VoIP SDK - Silverlight SIP softphone Javascript (I added this site for showing you the example program I found on the net.) Is it possible to build a Silverlight SIP softphone in Visual Studio 2008 with iPhone features? Thank you for your answer.
