Hello guys,

Recently, I'm working on a project to develop voice activation detection for my predicative dialer system. I'm using a sample program called Ozeki VoIP SIP SDK and I'm quite satisfied with it. This SDK is very flexible as you can implement it to already existing systems. You can use different developer environments such as Visual Studio 2010, Visual Studio 2008 or Visual Studio 2005. The support team helped me to configure the VAD to my actual needs. ;)
