There are a number of very old links from 2010 and 2013 talking about creating a high availability FreePBX cluster. But, they all basically say they don’t work with FreePBX 14 or 15 or the SNG7 based image.
Does anyone out there have an HA configuration on FreePBX 15 or 14 working today? If not, OMFG!!
If you do, or if you have heard of one, please tell us about your configuration and your experiences with it.
I’d love to find a solution that would fail over quickly and would not drop existing calls. If that’s not possible, a configuration that could detect failure and fully cutover in 5 seconds or less (ideally much less).
