What do you mean by mapping the 200 ?

In this example I can pickup any ringing extension:
http://www.voip-info.org/wiki/view/Asterisk+cmd+Pickup

"If phone with number 42 rings you can catch the call by dialing 742. You 
don't need to use the context"

exten => _7.,1,Pickup(${EXTEN:1}) works for all contexts.

Regarding call waiting, internally when I'm having a conversation and someone 
calls me, then my second line button blinks and I can pickup a second call 
putting first one on hold. Problem just with "real" call waiting from PSTN.

Thanks,
