The SLA code that is in Asterisk now will not completely support what I would 
consider real shared extensions.  It is intended to map some trunk (either real 
FXO trunk or IP trunk) to buttons on phones.  When any phone is making a call 
using that trunk, that line appearance on all of the other phones shows that it 
is in use.  It allows for barging into calls, as well as parking the call by 
simply putting it on hold.  Once a trunk is on hold, it can be retrieved from 
hold from any of the other phones (stations) that have this line appearance.
