seems indeed like the pairing was successfull at one point in time (the  
headset is rather taciturn in terms of feedback), because i was able to  
start BtHeadset.py and after a while that "waithing for call to finish"  
message appeared.
is the headset supposed to notify an incoming call? because i called the  
fr but the headset did not show any signs -- before investigation further  
i got distracted and did not return to the issue.
