Change audio route in ofono pulseaudio hfp

Asked by Madrake

I am trying to create a interactive voice response system (IVR) which attend calls from bluetooth connected phone automatically and plays recorded audio and listen for dtmf codes. Till now i am successful in connecting to bluetooth and attending calls and connecting it with the builtin speakers and mic. Is it possible to play audio directly from a recorded file instead of mic and change when i need it?
