Did you load module-bluetooth-discover with headset=ofono as argument?
Normally this should be sufficient to make it work. When the connection 
is established,
pulseaudio automatically loads loopback modules for the phone. You might 
have
to check if the modules have the correct source / sink.
Additionally to observing the log files, you can debug what is going on 
by using
dbus-monitor to see the messages on the dbus.

Unfortunately there is no HowTo as far as I know. Most stuff you find on 
the net is outdated.
