You need to connect the HSP/HFP profile in BlueZ in order to be able
to use it in PA.
As Tanu mentioned, this can be done calling
HandsfreeGateway.Connect(). You can do this in command line or using a
tool such as d-feet. People tend to think that Audio.Connect()
connects all audio profiles but this is not the case in BlueZ 4: you
have to explicitly call HandsfreeGateway.Connect() for HSP/HFP and
AudioSource.Connect() for A2DP.
Alternatively, you can initiate the connection from the phone. This
should work out of the box assuming the device is marked as trusted.
More importantly, in order to make all this work, you'll also need a
telephony component which implements the headset role (note that BlueZ
doesn't do this). I would recommend oFono 1.12 but older versions
should also work fine.
