It uses BlueZ through to get HFP working following the
org.bluez.HandsfreeGateway and org.bluez.HandsfreeAgent from the BlueZ
D-Bus API.
You need the HFP suport into BlueZ and the new dbus 1.3 with fd-passing
support.
Many thanks to Zhenhua Zhang <zhenhua.zhang@xxxxxxxxx> for its prototype
on this code.
