Please click the live help option down below to chat. As I said, the phonebook integration was tested on Elastix 2.5. I am not sure if they have big differences with other versions.
Another really important thing is that the elastix phonebook only appears if you have an extension associated to your elastix user, and if you open fop2 from within elastix, and not outside of it (by loading directly http://your.server/fop2)
You first need to log into Elastix, from there chose the fop2 menu option in the Elastix gui.
