High availability
With FortiVoice HA, you set up redundancy between two FortiVoice units in case of a system failure. FortiVoice HA uses an active-passive mode which means that you have a master (active) unit and a slave (passive) unit. These two units make up an HA group. The slave unit is not used until a failure occurs on the master unit and triggers the slave unit to assume the responsibilities of the master unit.
FortiVoice HA units use a heartbeat link to communicate. This heartbeat link lets the slave unit know that the master unit is up and running, and allows the master unit to copy configuration and data information to the slave unit whenever the master configuration changes. If a failure occurs on the master unit, the loss of the heartbeat triggers the slave unit to take over as the master and be a copy of that master unit.
