Default Bluetooth HF random Disconnect

Anyone else experiencing this? I have Nokia HF-208 (or something) and I get disconnected from it always during the call some 3min's after... Pick up the phone and the call is back on the phone speaker...

Tried it with Panosha 1.3->1.5 and now with Duttys 1.8 (so not about FW I think)
