It uses the Bluez protocol stack which is included in
kernels. Kphone is linked with -lbluetooth library, on
library is provided by libbluetooth1-dev.
I only tried with Bluetake BT400 G3 headset, with that
one it seems to
work fine, but it should work with any bluetooth headset.
- Make sure you have bluetooth support in the linux
bluetooth, rfcomm, sco, l2cap, and hci_usb if you
have USB bluetooth
dongle). Note that most laptops with bluetooth
support seem to have a

/etc/bluetooth/link_key on debian. If you delete the
file then you will
be prompted for the pin again once you try to establish
a connection to
the headset. Try to delete the file if you get
"Permission denied" when
