asterisk users - Mar 2006 - Bluetooth headset in handsfree mode with SJPhone or X-lite

Hi,

After much searching I have found that it might be possible to get a 
bluetooth headset to answer/hangup with SJPhone or Xlite if the headset 
supports handsfree mode. My Toshiba bluetooth stack supports this but I 
have not been able to figure out how to enable it. Also Windows XP 
desktop bluetooth stack does not support handsfree but Windows CE does 
(go figure). Has anyone got handsfree mode working with a bluetooth 
headset? How about working with SJPhone or Xlite or some other SIP 
phone? For some reason the SJPhone when used with a bluetooth headset 
disconnects/reconnects bluetooth when the answer/hangup button is used 
on the headset (how the hell did that come about). Using a bluetooth 
headset with a SIP phone and asterisk would really help me by removing 
those pesky wires....

Thanks
