Callee ID (not Caller)

I am starting an executive suite (like Regus). I am providing phone service as part of the service for the tenants. With over 30+ tenants, my live receptionist needs to see the number being called (Callee ID) so she can answer the call appropriately using the right business name. 8x8 has a product called "Switchboard", but the only product RC has that is close is "Multi-site support".... is there a solution I am not seeing?
