Problems with microfone on bluetooth dongle

Hardware Support
1

Hi,
I got an Asus USB BT-500 Bluetooth Dongle and installed it.
It works pretty well with playing audio but I can't get the Microfone running when using headsets, e.g. the yealink headset.
It seems impossible to change into the necessary handsfree mode.
some Code:

rfkill --output-all 
ID TYPE      DEVICE TYPE-DESC      SOFT      HARD
 2 bluetooth hci0   Bluetooth entsperrt entsperrt

Anyone any idea what to do?

Problem solved by upgrading to Zorin17pro. Seems the new software solved the problem.
