How to adjust (increase) USB/BlueTooth microphone level

I'm using a vvx 601 firmware 5.6.x in SfB mode in combination with a Jabra evolve 65 MS headset.


When making a call using the headset my counterparts complain about too low voice level. When using the handset the voice level is quite fine.

I've tested with two different sets of Jabra headsets and a set of Sennheiser bluetooth headsets. All with the same result. Connecting the Jabra evolve over USB the voive level is even lower.


Is it possible to adjust (increase) the USB / Bluetooth Microphone level?
