1. Physically connect the FortiVoice units that will be members of the HA group.
You must connect at least one of their network interfaces for heartbeat and synchronization
traffic between members of the group. For reliability reasons, Fortinet recommends that you
connect both a primary and a secondary heartbeat interface, and that they be connected
directly or through a dedicated switch that is not connected to your overall network.
2. On each member of the group:
• Enable the HA mode that you want to use and select whether the individual member will
act as a primary unit or secondary unit. For information about the differences between
the HA modes, see “About high availability” on page 53.
• Configure the local IP addresses of the primary and secondary heartbeat and
synchronization network interfaces.
• Configure a virtual IP address that is shared by the HA group and remains the same after
a failover. The virtual IP address is used to auto-provision the server IP address and the
SIP trunk client IP address.
• Configure the behavior on failover, and how the network interfaces should be configured
for whichever FortiVoice unit is currently acting as the primary unit.
3. If you want to trigger failover when hardware or a service fails, even if the heartbeat
connection is still functioning, configure service monitoring. For details, see “Configuring
service-based failover” on page 66.
4. Monitor the status of each group member. For details, see “Monitoring the HA status” on
page 57. To monitor HA events through log messages and/or alert email, you must first
enable logging of HA activity events. For details, see “Configuring logging” on page 243.
Monitoring the HA status
The Status tab in the High Availability submenu shows the configured HA mode of operation of
a FortiVoice unit in an HA group. You can also manually initiate synchronization and reset the HA
mode of operation. A reset may be required if a FortiVoice unit’s effective HA mode of operation
differs from its configured HA mode of operation, such as after a failover when a configured
primary unit is currently acting as a secondary unit.
For FortiVoice units operating as secondary units, the Status tab also lets you view the status
and schedule of the HA synchronization daemon.
Before you can use the Status tab, you must first enable and configure HA. For details, see
“How to use HA” on page 56.
To view the HA mode of operation status, go System > High Availability > Status.
