Shared call-waiting queues

Workload can be shared amongst several attendants by having call-waiting queues bound to several consoles.

The system ensures that in-bound call(s) and call-waiting queue(s) state are presented to all attendants in a consistent manner and updated in real-time. The same capability can be used to implement call coverage strategies or to ensure the continuity of the front-desk service across different distant offices or time zones.
