Best version for centos 5?

I have a centos 5.11 32 bit server, it has (old) asterisk running on it but I’m thinking of stripping it out and replacing it with freepbx. Which freepbx version is best for centos 5? will the latest version go on?

Please do yourself a favor and install FreePBX from our Distro which will give you a fresh Linux at the same time.

it’s taken me ages to build this machine up to do everything it does, it would be easier to install freepbx on it as it is rather than build the whole machine up again.
