Configuring high availability

Optionally, configure high availability (HA) on the primary and secondary FortiVoice phone systems at the main office. Make sure to set the correct virtual IP address because this IP address is used throughout the local survivability setup.

1. Physically connect the primary and secondary FortiVoice phone systems 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. Connect to the web-based manager of the primary FortiVoice phone system at the main office.
3. Go to System > High Availability, and click the Configuration tab.
4. Configure the HA options, as applicable.
   • HA configuration
   • Advanced options
   • Interfaces
   • Service monitoring
5. For more details about configuring HA, see the Configuring the HA mode and group section in the FortiVoice Phone System Administration Guide.
6. HA settings, with the exception of virtual IP Address settings, are not synchronized and must be configured separately on each primary and secondary FortiVoice phone system.
7. Connect to the web-based manager of the secondary FortiVoice phone system at the main office.
8. Go to System > High Availability, and click the Configuration tab.
9. Configure the HA options, as applicable.
   • HA configuration
   • Advanced options
   • Interfaces
   • Service monitoring
10. For more details about configuring HA, see the Configuring the HA mode and group section in the FortiVoice Phone System Administration Guide.
