Delay Announcement Devices. The system manager can
designate as many as ten primary delay announcement devices
per group rather than the single device for each group that is
available in Release 4.2 and earlier systems. Furthermore, an
additional secondary delay announcement device can be
specified, for a total of ten primary device extensions and one
secondary device extension per group.
A primary delay announcement device operates in the same
fashion as a single delay announcement device, playing once,
as soon as it is available, for the caller who has waited the
longest for a calling group agent and has not heard a primary
delay announcement. If a secondary announcement device is
used, it can use the factory setting, which plays the
announcement once, or it can be set to repeat the
announcement after a certain amount of time. The system
manager programs the time (0–900 seconds) between primary
and secondary announcements. This setting controls both the
interval between primary and secondary announcements and
the interval between repetitions of the secondary announcement
if it is set to repeat.
The primary and secondary announcement options, when used
together, allow an initial message to play for callers, followed by
a repeating announcement that, for example, urges callers to
stay on the line and wait for a calling group member.
Two or more groups may share an announcement device.
Enhanced Calls-in-Queue Alarm Thresholds. Three Calls-in-
Queue Alarm thresholds can be set to more clearly indicate the
real-time status of the queue according to the behavior of
programmed Calls-in-Queue Alarm buttons. In earlier releases,
only one Calls-in-Queue Alarm Threshold setting is available to
activate the LEDs at programmed Calls-in-Queue Alarm buttons
for a calling group.
Using all three levels, the system manager sets Threshold 1 to
the lowest value, Threshold 2 to a middle value, and Threshold
3 to the highest value. A Calls-in-Queue Alarm button indicates
the severity of the alarm conditions in the following ways:
20
— If the number of waiting calls is less than the value
programmed for Threshold 1 or drops below that level,
the LED is unlit.
— If the number of waiting calls is greater than or equal to
the Threshold 1 value but less than the Threshold 2
value, the LED flashes.
