Figure 20:Active-passive HA group
You can mix different FortiVoice models in the same HA group. However, all units in the HA
group must have the same firmware version with the same hardware. For example, FortiVoice
200D and 200D-T models cannot be in the same HA group due to hardware differences, but
200D and FortiVoice VM can be in the same group because neither of them has PRI or FXS/FXO
ports.
When mixing FortiVoice models, the HA group is limited by the capacity and configuration limits
of the least powerful model.
Communications between HA members occur through the heartbeat and synchronization
connection. For details, see
To configure FortiVoice units operating in HA mode, you usually connect only to the primary unit
(master). The primary unit's configuration is almost entirely synchronized to secondary units
(slave), so that changes made to the primary unit are propagated to the secondary units.
Exceptions to this rule include connecting to a secondary unit in order to view log messages
recorded about the secondary unit itself on its own hard disk, and connecting to a secondary
unit to configure settings that are not synchronized. For details, see
