Freepbx version for trunk balancing module


I want to use the free module for trunk balancing. I have been using elastix 2.5 for a couple of years but I couldn’t make it work so I decided to install a machine with freepbx to do this job.
Do you have any recommendations on which freepbx version is the most stable and works well with the module to start with?

Thanks in advance

Use the latest stable 64 bit distro with FreePBX 13. I got a confirmation from a user a few months ago that Trunk Balancing still works in 13.

Thank you for your reply. I am installing the distro 10.13.66 from this link. Should I update it or keep it as it is?

Also which version of Asterisk should I go for the most stable result?

Thanks in advance
