Bluetooth on PC

[Zattaltin]

I have the USB dongle installed and ready to go I can actually connect the headset to the computer so it says that it is connected, but I don't have a Bluetooth stack that can run the VoIP as far that I can tell. Can someone help me out with this? In device manager there is no "Bluetooth Radio" as many instructions say there should be. All I want to do is have a Bluetooth mic for games online.

I have a Plantronics 815 and a azio usb
