I think you need the Hospitality Package for those options to work. If you have that package, then Matt85 is correct (mostly). You do need to have a feature access code programmed. The other thing you need to know is how to use the feature access code. In the Folio Documentation, there should be info on that.
The documentation will tell you that you need to add an additional number to the feature access code to make it work. something like 0=maid in roomdirty, 1=maid in room clean, etc... To make it work, the user would lift the handset, dial the feature access code + the additional number. I cannot remember what the additional numbers correlate to, so please look it up.
Good Luck.
