You have to change the source of the corresponding loopback module.
Probably you have to load the module manually, that means loading
module-bluetooth-policy with hfgw=0.
You can find an example in the sources I sent you on 13th of May.
I am loading the loopback modules manually and also allow switching
of the input/output device during a call.
Take a look at pulsecontrol2.py (move_source_output_module(),
move_sink_input_module()) and the use of the functions in 
phoneconnector2.py.
