On my XV6700 if I had a bluetooth headset paired and an incoming call came in and I picked up the call with my handset (i.e. hitting the soft key on the phone to answer) then the conversation would be had on the handset
and
if I picked up the call with my bluetooth headset, then the conversation would be had on the bt headset.

With my XV6800, if I pick up the call with the handset, it seems like for a brief second, the call will be on the handset but then bluetooth seems to grab it back. I eventually can click on menu->turn hands free off to get it to stay on the handset.

Can anyone help me get it so that if I answer via my handset it stays there without BT grabbing it back?
