I am going to assume that you are not a dealer?To upgrade you would need the new software,Ram 2 card and the Misc 2 card.Enabling the cid isn't that hard you assign trunks as cid trunks and allow it on a station basis.You can also decide whether name or number appears first.
You also need to assign review blocks if needed.
