From the Asterisk NOW release that included FreePBX. This is a recent build from December 2013.
CentOS 6.4 with Asterisk 11.6
Currently FreePBX 2.11.0.20 with the updated core 2.11.0.30. Planning on doing 2.11.0.32 later this evening.
I did some package updates with Yum prior to asking this question and was lucky I had a VM snapshot just before I doing that. I am not sure if it broke any telephony functionality but the GUI was not happy so I decided to rollback and try to get smart online.
This is going to sound dumb, but I can’t exactly remember how I ended up with FreePBX. I thought I installed AsteriskNOW and it gave me the option to install FreePBX. I do remember starting over a few times. I originally used a production build VM template we use of pure Asterisk as a B2BUA. This didn’t give me all the features I needed for our NOC. We needed the IVR, ring groups, etc.
However, that stable build link looks very familiar.
To find out what version your FreePBX Distro is please execute this command from the Linux CLI.
cat /etc/asterisk/freepbxdistro-version on older systems
cat /etc/schmooze/pbx-version on newer systems
