Ofono is not necessary AFAICT, pulseaudio has a native backend
(headset=native option).

Could you attach the output of pactl list when you have your device paired?

Ubuntu 16.04 has a different version for bluez, this may be related.
The issue might be in bluez and not in pulseaudio. To debug this,
please attach:

1. The output of `pactl list` with the device attached
2. A verbose log of pulseaudio when pairing the device[1].

Please remove the headset=ofono option from the configuration, so that
the native backend is used. AFAICT the ofono support does not bring
the features you need[2]
