Depending on the reason for the failure, some Communication Manager features may not work as administered. If the failure is on the main server but the network is still intact, you may not see any changes to features, such as call forwarding, hunt groups, and call coverage. If the network fragments, the same features may or may not work as intended.
Note:
Features may act differently depending on the release of Communication Manager.
This section highlights how a failover would affect the Communication Manager features.
