In the scenario, all new calls for a given customer application are routed by the public network to only one of the switches in the network, where the calls are put in the queue.
Local agents service the calls from the queue in the normal fashion. However, remote agents service calls by means of Enhanced Look-Ahead Interflow (LAI).
The Communication Manager server with the call queue does rapid enhanced look-ahead attempts to all other switches in the network that can service this call type, looking for an available agent.
Normally, the look-ahead attempts are placed only on behalf of the call that is at the head of the queue (interflow-qpos = 1). However, in scenarios where there are large numbers of agents at a remote Communication Manager, interflows on behalf of more than one call can be necessary to outflow a sufficient volume of calls to keep all agents busy (interflow-qpos <= 2).

Interflow call attempts are placed on behalf of the call that is at the beginning of the queue every five seconds to the two other Communication Manager in the network.
If queuing times are very long, five minutes, for example, and the call is not near the beginning of the queue, going through the vector loop from step 4 to step 7 every 5 seconds is of no avail. The FIFO processing vector is more efficient.
