How to develop Voice activation detection in C#?

[C# Programming]

Hello,

I'm developing a VAD in C# and I'm using a sample program, it is called Ozeki VoIP SIP SDK. It's quite useful as it provides documentations and source code. But I'm not sure about its flexibilty. Do you know if it is compatible with other system or not?
You can find the sample program here: http://www.voip-sip-sdk.com/p_238-voice-activation-detection-voip.html[^ (http://www.voip-sip-sdk.com/p_238-voice-activation-detection-voip.html)]

Thanks,

Will
