Abstract: In a computer-telephony integrated (CTI) contact center, a CTI adjunct (160) enqueues contacts in contact queues (184) of the CTI adjunct, but also causes contacts that are calls (168) to be enqueued as ACD calls in ACD call queues (120) of an ACD system (101), whereby the ACD system and its management information system (MIS 110) provide ACD features to the calls. Similarly, the CTI adjunct enqueues agents in agent queues (185) of the CTI adjunct, but also causes agents (102-104) that have call-handling skills to log into and to be enqueued as ACD agents in ACD agent queues (130) of the ACD system, whereby the ACD system and its MIS provide ACD features to the agents.

Abstract: A system for using an under-utilized data channel for carrying additional data, in a network mode. One such channel is the D-channel in the ISDN system. In one implementation, a group of telephone call centers share data, using the D-channel, about the lengths of time incoming callers must wait before being answered. Using the shared data, the call centers collectively route incoming calls to call centers having smaller waiting times.

Abstract: In a computer integrated telephony call center where an adjunct host (160) normally controls enqueuing of calls (168) in call queues (120) of an ACD system (101) and corresponding call queues (120′) of the adjunct host and assigning of the enqueued calls to agents, the ACD system assumes (604) control over its call queues upon loss of the control by the adjunct host (e.g., upon failure (600) of the adjunct host). The ACD system flags (602, 606) all calls that are enqueued at the time of loss of the adjunct host control as well as all calls that the ACD subsequently enqueues as being under ACD system control. When the adjunct host regains its control ability, the ACD system stops flagging new calls, call queues of the host processor are cleared (702), and the adjunct host regains control (722) of enqueuing calls in call queues of the ACD and the adjunct host.

Abstract: An arrangement for lookahead interflowing traffic among a plurality of serving sites of one customer. Incoming calls received at a site are queued if they cannot be served immediately. Queued calls are then examined periodically and if the call has not yet been served by a local agent and if the call is one of the oldest call in the queue, then the call is a candidate for lookahead interflow. A candidate for lookahead interflow causes a message to be sent to another switch requesting that the call be interflowed. If the other switch accepts the call, the call is routed to that other switch; if the other switch does not accept the interflowed call then the call remains in the queue of the requesting switch and is reexamined at the next period. All calls in the queue are completed to a local agent if a local agent is available.
