FreePBX High Availability Disaster Recovery
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 also use as an online management tool to easily switch between nodes.
