Fortinet fortivoice Administrator's Manual page 61

You must maintain the physical link between the heartbeat and synchronization network
interfaces. These connections enable a group member to detect the responsiveness of the
other member, and to synchronize data. If they are interrupted, normal operation will be
interrupted and a failover will occur. For more information on heartbeat and synchronization, see
"About the heartbeat and synchronization" on page
You can directly connect the heartbeat network interfaces of the two FortiVoice units using a
crossover Ethernet cable.
