Chapter 20: Redundancy Configuration

For scenario two, where the Softswitches are on different LANs, the network between
the two LANs must have at least 1Mbps bandwidth and at most 200 ms latency.

Switchover Considerations

Before you implement redundancy, you should understand what happens when the
system switches from the active server to the standby server.
In the following cases, MAXCS will switch control of the system from the active server to
the standby server:
When an administrator clicks the Manual Switch Over button (see Manually
•
Switching Servers on page 208).
• When the active system shuts down or restarts, if the setting Automatically
assume control when active system is not available. See Figure 20-4,
"Redundancy configuration dialog box".
• When the network of the active server disconnects, if the setting Automatically
assume control when active system is not available is selected.
When system control switches from the active to the standby server, it affects calls in
the following ways:
Current calls will be disconnected. Within a few minutes, new calls will go through.
•
• CDRs are dropped for all calls, including connected calls.
• Voicemail recording stops.
