Failover time conditions
The default failover time is 15 seconds; however this may be adjusted in the Failover time setting (for
more information, see
"Configuring a Master Spectralink IP-DECT Server 6500" on page 149
).
A failure is detected within 15 seconds, and the server will wait the specified failover time before ini-
tiating the failover operation.
The failover operation moves the users handled by the failing peer to the working peer by re-regis-
tering them to the PBX.
When re-registration is completed, the users are able to receive calls again. Outgoing calls can be
performed shortly after the failover.
The speed of re-registration depends on the PBX, and the load on the system.
Failure on the Backup Spectralink IP-DECT Server 6500
A failure of the backup Spectralink IP-DECT Server 6500 will induce a short service outage, and the
master Spectralink IP-DECT Server 6500 will reestablish full operation as a single server solution.
If the backup Spectralink IP-DECT Server 6500 resumes its operation, it will automatically return to
be part of the redundant system. In case the backup Spectralink IP-DECT Server 6500 has to be
replaced, the new backup Spectralink IP-DECT Server 6500 must be added to the solution.
