Communications Server and Siebel Universal Queuing
Siebel Universal Queuing is an optional infrastructure module that routes communications work items to agents. Agents are notified of the work items through the communications toolbar.
Siebel Universal Queuing can route work items of predefined channels such as email (for Siebel Email Response) or voice calls (for Siebel CTI). It can also route work items of new channel types that you implement.
For more information, see Siebel Universal Queuing Administration Guide.
