[asterisk-users] Can I install Asterisk normally and then installing the GUI "asterisk now"

[bilal ghayyad]

Hello;

Is it possible if I have already asterisk installed on Fedora machine to install the GUI "asterisk now" without doing a fresh installation using the Asterisk Now CD? 

Which version of the GUI that should be selected to work with the asterisk version? For example, if I have asterisk 1.8 then which GUI version to select? "I am talking about compatibility".

Can I say that Freepbx is Asterisk + Asterisk Now? 

Regards
Bilal
