This is "call waiting"; if you can find a way to disable call waiting in 
the Polycom config, it will work the way you desire. I've looked for it 
before (briefly) and couldn't find it, but if you can figure out how to 
do it please let us all know :-)

There are ways using SetGroup and CheckGroup to accomplish this in the 
dialplan, but it's better to let the phone handle it (because if it 
works, you can go back to registering three line appearances to the same 
SIP username and it will work properly).
