FreePBX High Availability
Commercial Module
FreePBX High Availability is not supported on FreePBX 14+ and SNG7 Distros.
These wiki pages are kept for historical purposes, all versions of FreePBX and PBXact that support the High Availability module are end of life and end of support.
Free PBX High Availability (HA) is a commercially developed High Availability solution that has reworked the FreePBX platform to integrate DRDB, Cluster Manager, and Pacemaker. This enables automatic mirroring and failover between two FreePBX Systems. Your phones and devices are registered to a floating IP address, so the failover between systems will be transparent to them. Your SIP Trunks will register to the active node, and if utilizing a PSTN Failover Appliance (optional), your T1 or Analog lines will be directed to the active node as well. Then when the primary PBX is repaired or recovers, you can switch back to the primary FreePBX node in just seconds.
Setup and configuration of FreePBX HA is done in the FreePBX GUI, which you can use as an online management tool to easily switch between nodes.
Our new FreePBX HA Appliances provide out-of-the-box support for FreePBX High Availability (HA) solutions. If your voice communications are mission critical, and data, revenue, productivity, and reputation are at stake, you need a FreePBX HA Appliance!
The FreePBX High Availability (HA) Commercial Module is a module designed to work with the FreePBX Distro 10.13.66 or Older only. When installing the FreePBX Distro, make sure you pick one of the (HA) options to enable this module to work.
It's recommended (but not required) that you install the Asterisk 11 distribution when running FreePBX High Availability. At this time PJSIP is not supported with HA and you will need to use chan_sip
Due the complex UI, we are currently unable to offer support with any issues encountered with using IE less than 10. We strongly suggest the use of Chrome to manage your FreePBX System.
