When there are available agents, calls are always delivered to available agents at the queuing Communication Manager before available agents at the remote Communication Manager.

When there are calls in the queue and agents serve calls from multiple applications, the agents always service calls from the applications that are queued locally before calls from applications that are queued at another Communication Manager.

Use backup VDNs and vectors ito provide continuous operation in the event of a failure at a queuing Communication Manager.

EWT predictions cannot be made if the split or skill in which the calls are queued has no working agents.

EWT predictions can be temporarily inaccurate if there are sudden, major changes in the number of working agents in the split or skill in which the calls are queued.
