Contact centers use multiple vectors with the same basic call flow but unique settings, such as announcements, route-to destinations, holiday tables, and conditions. With VDN variables, system administrators can create a generic call flow vector. VDN variables reduce the number of vectors, ensure common flows and ease of administration. The system administrator can use VDN variables as indirect references to announcement extensions and other sources.

For more information about VDN variable configuration, see the VDN configuration section in Administering Avaya Contact Center – Extended Capacity.
