Did you check with "pacmd list-sinks" and "pacmd list-sources" if the 
bluetooth sink and source are
available? Did you check if loopback modules get loaded?
If they get loaded, please check if they are loaded correctly. There 
must be one module with source
set to your phone and sink set to your default sound device and one 
module in the other direction.
You should also see some output of the loopback modules in the 
pulseaudio log.
