4 Features
Group-Assigned Features
starting with the first extension assigned to the group through system
programming.
Up to 10 primary and one secondary announcement devices can be designated
for each calling group; more than one calling group can use the same
announcement devices. The announcement devices should not be assigned as
group members, and they are outward-restricted to prevent unauthorized calls.
Each calling group can have only one telephone assigned as its message-waiting
receiver. The same telephone can be assigned as the message-waiting receiver
for more than one calling group.
Three Calls-in-Queue Alarm thresholds can be set to more clearly indicate the
real-time status of the calls waiting in the queue according to the behavior of
programmed Calls-in-Queue Alarm buttons. In Release 4.2 and earlier, 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 3 to the highest value,
Threshold 2 to a middle value, and Threshold 1 to the lowest value. A
Calls-in-Queue Alarm button indicates the severity of the alarm conditions in the
following ways:
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.
If the number of waiting calls is greater than or equal to the Threshold 2
value but less than the value for Threshold 3, the LED winks.
If the number of waiting calls is greater than or equal to the highest value,
Threshold 3, the LED lights steadily.
If all three thresholds are set to the same value, the result is one threshold only
with LED state either off or on (steady). If two values are the same, then the result
is two alarm levels (flash, steady). The factory setting is one call for all three
thresholds with LED states of off and steady.
In Release 5.0 and later systems, the primary delay announcements function like
the single announcement available in prior releases. After the delay
announcement (the primary delay announcement in Release 5.0 and later
systems), an inside caller hears a special ringback, a transferred inside caller
hears regular ringback, and an outside caller (including a transferred outside
caller) hears special ringback or Music On Hold, if programmed, until the call is
answered by a calling group member. The delay announcement or primary delay
announcement is played only once while the call is in queue.
In Release 5.0 and later systems, the system manager can specify the extension
for an optional secondary delay announcement and use system programming to
set the interval (0–900 seconds) between announcements. This setting
determines the time before a waiting caller hears the secondary announcement
