The Avaya Contact Center – Extended Capacity solution provides High Availability (HA) and supports the active/alternate HA model. Active servers host virtual IP (VIP) addresses and manage contact center activity. The solution provides alternate servers to ensure high availability. The level of the contact center high availability depends on the solution deployment environment. The system administrator can deploy the contact center in the Simplex, local HA, or geo-redundant HA environment.

Avaya Contact Center – Extended Capacity supports geographic data resiliency and disaster recovery. The administrator can configure the contact center without Layer 2 networking. In case of failure, the contact center assumes that the primary data center is not recoverable and restores the data and services to survivable components in the secondary data center. Contact center deployment with disaster recovery networking does not preserve the state of agents and active calls.
