You have to do all of the configuration mentioned here[1] for *each* number. 
Afterwards, you have to route the incoming call to an internal device. As I'm 
using FreePBX, I don't know how to do it *correctly*.

Solution:
You have the choice between: programming your PBX yourself (and have the struggle 
and pain) or let this pretty difficile job do others for you - they provide 
extremely good solutions for a lot of telephony features - it makes no sense to 
reinvent those features without having the required knowledge - so, use FreePBX. 
But it's of course your decision.
