clgjr,
I had one client a long time ago that had a flash lite. from what i remember it only went with the cics. the cics has a built in auto attendant and that is where you need to change the greeting. Sorry to say that i don't even remember how to do it. I do remember it being a pain in the a**.
As rich mentioned it can be upgraded. it's just a matter of punching in a key code. its not that expensive to upgrade, and the customer will have a fully functional flash.
