The FreePBX Distro has some built in features to allow you to change the Major Asterisk version you are using. To change which Major Asterisk release you are using, log in using SSH and your root password and type:
You will then be prompted to pick which Asterisk version you would like to switch to. Once the switch has been completed you will be informed which version you are running and that Asterisk is restarting. FreePBX will then perform a reload and re-write all the configuration files based on the version of Asterisk you switch to.
