Support for HFP actually involves 3 daemons

- BlueZ5 which takes care of pairing, device detection / discovery, etc.
- oFono which takes care of HFP protocol details and establishment of 
the SCO connection
- PulseAudio which transmits / receives the data on the SCO link and 
"plays" it.

It looks like your PulseAudio is either not installed or not the version 
that works with oFono.

The oFono and BlueZ changes for HFP are currently in a 'released' state 
(e.g. part of an official release).  I'm not sure whether the PulseAudio 
changes are...
