Are you planning to get rid of the legacy PBX completely?  Or is
Asterisk going to be a second PBX?

I am going to assume you are replacing the legacy PBX.  You can setup
analog extensions so that you have multiple phones on each FXS channel. 
But they will be like a party line.  If you put 6 phones on one FXS, all
6 ring at the same time, only one person can use that extension at a time.

However you can add SIP phones to Asterisk and each can have their own
extension instead.  It just requires cat 5 cable back to a switch for
each phone.
