When the Avaya Workplace Client connects to a IP Office system, it can also be given details of an alternateIP Office system to use if the current system fails.
When that occurs, after about 3 minutes the Avaya Workplace Client automatically connects to the alternate system. This is called failover.
If this occurs whilst the Avaya Workplace Client has a call connected, it will try to continue the call and only failover when the call is ended.
Some features, such as switching twinning mode, are not available during resilience.
During failover, Avaya Workplace Client displays call records for both before and during failover. After failback, call records from during failover are lost.
Once the original system has been restored, the Avaya Workplace Client reconnects to it. This is called failback.
