I just installed asterisk and frepbx. Everything seems to work fine, except I miss several modules.
For example there is no ring groups module in my web interface.
You must be new to FreePBX, take a deep breath, relax and scan the Web GUI. See the column on the left hand side. Look at the second item down. Now if you found that already and still don’t see what you need when you are in the Module Admin , take a look along the top you’ll want to check for updates. That will get you all the latest stuff.
It takes a little bit to get used to the interface and where everything is placed but playing and poking around to learn where everything is for 15 minutes will help greatly.
