•
If the master (Leader) Signaling Server is unavailable, a Follower
Signaling Server becomes the IP Telephony node master.
•
Signaling Servers share telephone registrations (load-sharing).
•
If a virtual trunk is unavailable, virtual trunk redundancy occurs (that is,
the call-processing software selects an alternate route).
•
Signaling Servers can be configured for different types of redundancy for
their software components (for example, Alternate Gatekeeper, Failsafe
Gatekeeper).
•
If the Primary Gatekeeper is unavailable, you can configure an Alternate
Gatekeeper (automatic database synchronization).
•
If the Primary and Alternate Gatekeeper are unavailable, you can
configure a Failsafe Gatekeeper (at each Signaling Server).
