VoIP: Connect Bluetooth headset with Cisco 7940 (Phone&PC are connected). How (&possible)? - ip phone headset

I would be with a Bluetooth headset and a VoIP phone Cisco IP Phone 7940 Series. The PC and connect the phone to connect to, because I can call directly from Outlook and are connected to the phone.
I thought to be the headset via a PC connected to the phone.
Ideas?
Thanx
