SV9100 Networking Manual
For centralized voice mail the voice mail must be installed in the Primary System
(Site A). Assigning Top Priority Primary System and Primary System Automatic
Integration are recommended.
Specify the communication server in Site-A for the Top Priority Primary
System
Site-A becomes the Primary System. Without this function, either Site-A or Site-B
can become the Primary System.
Enable Primary System Automatic Integration
When Site-A is disconnected from the LAN, Fail-Over works and Site-B becomes
the Primary.
If you would rather stop the Fail-Over function, you can disable it by setting Program
51-05-02 to 0. With it disabled, Site-B is locked while the Primary System is down.
If Site-A connects to the LAN again, the Automatic Integration function reestablishes
the NetLink and Site-A becomes the Primary. Without this function, Site-B remains
the Primary.
Create a Recovery Database – Recommended.
Because each communication server database and communication server
configuration is updated by the Primary System, creating a recovery database is
recommended. This may be needed if the communication server goes back to a
stand-alone server.
Refer to the
Section 8 Communication Server Database Synchronization on page
10-37
and
Section 9 Create Recovery Database on page 10-39
