Edit /etc/bluetooth/audio.conf
# Configuration file for the audio service # This section contains options which are not specific to any # particular interface [General] # If we want to disable support for specific services # Defaults to supporting all implemented services #Disable=Control,Source # SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA) # Defaults to HCI SCORouting=PCM # Headset interface specific options (i.e. options which affect how the audio # service interacts with remote headset devices) [Headset] # Set to true to only support HSP # Defaults to false DisableHFP=false # Just an example of potential config options for the other interfaces #[A2DP] #SourceCount=2
The important part is the SCORouting.
Connect and setup the headset

During the call
After having answered / placed the call, switch the audio to the bluetooth headset. You need a small workaround to get audio in, which is included below.
alsactl -f GSMBLUETOOTH.txt restore ./bluetooth_pcm &
the workaround is to switch Capture Left Mixer first to Analogue Mix Right and then back to Analogue Mix Right. This can be done with alsamixer:
alsamixer
(lookup Capture Left Mixer in the "gui" and toggle the value).
