Telephony API for QT (not Symbian)

Does anyone knows if an API exists within Standard QT (Commercial) for Windows ? I know there is something about telephony in QT Symbian but I want to build a program that make a phone call and read a specific set of phone key pressed by the callee when he answers the call ?

Thank you !

I don't think there's such functionality in Qt. You can check VoiceXML where such things can be done easily, thought you'll need some more stuff to work with (server, voice browser, etc).
