place to intercept BT audio packets?

New to ofono: looking for documentation/pointers that can inform about 
the best point in ofono to intercept Bluetooth audio packets from/to 
headset to implement custom audio processing (and does audio stream even 
thread through ofono?).

All info appreciated!

I don't think audio stream goes through ofono. Sorry.

oFono does not process the audio stream, it only sets up the transport. 
The actual packets are processed by PulseAudio or directly routed from 
the sound card to the Bluetooth chip in hardware.

This is a fairly complex topic.  I would ask this question on the BlueZ 
and / or Pulse Audio mailing lists.

This is an understatement :)

Many thanks to all for the feedback! The stream is elusive, but we'll 
find it sooner or later ...
