High availability is a characteristic of a system which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.
Make a high-availability cluster out of any pair of VitalPBX servers. VitalPBX can detect a range of failures on one VitalPBX server and automatically transfer control to the other server, resulting in a telephony environment with minimal down time.
We have created an article that talks about this.
