The project you mention is about 'Bluetooth HandsFreeProfile support for 
Asterisk'. Then, you can use the computer as a handsfree device: you 
carry the phone in your briefcase and the laptop in the desk, so you can 
  make/receive calls without speaking to the phone -you speak to the 
laptop.
A different thing is to use the phone as audio input: in this case you 
want to speak to your phone, but you want the streaming audio to reach 
the computer via bluetooth in order to use VoIP there (for example). So 
you use the phone just like a headset, the difference is that you have 
to hold it by hand instead of hook it in the ear. This way, all you need 
in the Linux point is Bluez and btsco (bluetooth-alsa) in order to have 
AudioGateway support. The problem is what you need in the phone end: I 
think at least Symbian, and the possibility to "read/write" from/to the 
phone audio device and implement the headset profile.

Do you think is it possible? Has it been managed anywhere?
I guess many people wouldn't like the idea at all...
