Unhappy [Q] Bluetooth Voice Dial / Voice Command

Hello, i cannot get Voice Dial to work.

I use a Plantronics M55, which should - on long button press - initiate the phone's voice dial. I tried a lot of apps, whatever I try: nothing happens. I also miss a profile for 'remote control', in blootooth settings I only see phone audio and media audio.

Anyone got this running? Seems Sony forgot the bluetooth profile :/

Thanks for any hint!
