[Blind-sysadmins] Fusion PBX: how to get feature codes working in calls?

Hello Everyone. I have installed fusion PBX as recommended and it seems to be working fine. What I can't seem to get working is the feature codes during a call. Non of the star codes referenced in the user guide work, and I can find no reference within the various sections of fusion PBX to a feature codes module or app. The most important code I need to work is toggling call recordings during a call. Sometimes, it's necessary to pause the recording when someone provides credit card info for example. star 2 sounds like it would do the trick. Does anyone have any idea what I need to do to get in call codes working? This is a stock install and very few settings have been changed. Many thanks, Mo.
