Mobile Headsets I Want To Use My Bluetooth Enabled Mobile As Headset For IP Calls Made From My Bluetooth Enabled Laptop. How?

I want to use my bluetooth enabled mobile as headset for IP calls made from my bluetooth enabled Laptop. How? - mobile headsets

I use my cell phone with Bluetooth, such as a headset for VoIP calls from my laptop with Bluetooth. Is it possible? I know I can use it backwards, ie my laptop to my Bluetooth headset. My phone N95. Please advise if possible .. Any software available for download, etc.? Thank you.
