Currently this doesn't seem to be automatic in any of the distros.

The generic answer is to activate gsmheadset.state, and adjust the volume 
settings in it to match your preference. The correct way to do this will vary 
depending on which distro you are using. The most generic is to use alsactl:

alsactl -f /usr/share/openmoko/scenarios/gsmheadset.state restore

FSO has a dbus interface for this, and a rules engine that may be able to 
handle the switching if the phone app doesn't. The dbus call can be made from 
the command line:

mdbus -s org.freesmartphone.odeviced /org/freesmartphone/Device/Audio 
org.freesmartphone.Device.Audio.PushScenario gsmheadset

Another option may be pymixer - see link at end of [1]

In either case you will need to run this after the start of the call as the 
phone app is likely to load gsmhandset.state when you pick up the call.
