Bluetooth Mic not working

[blakamin]

Sometimes my BT mic on my headsets doesnt work.
People cant hear me on 2 different BT headsets and when I use my dialer, the tones don't come through the headset... If they do, my mic works.
This happens randomly. More often than not, it doesn't work.
I have searched and tried allsorts of BT reg edits and still nothing.
I'm running Lennys 6.1 (newly cooked this morning) but this also is the case with Helmi's and WM6.
Any help would be appreciated

Cheers
