FEATURES AND SERVICES
While off-hook on a queued call, a single-line user can transfer or conference the
call.
● On-Hook Queuing
The caller can hang up after a call to a busy station goes into queue. The call retains
an association with the on-hook calling terminal, and a callback will alert the on-hook
user when the queued-for station is available.
After a single-line terminal user goes
on-hook, the queued call cannot be accessed until a callback attempt occurs. During
the waiting period, the single-line user can place or receive other calls.
When a multiline user hangs up after a call is queued, the green status LED of the
queued System Access (SA) button winks, as if the call is on hold. If the user goes
off-hook and presses the button while the call is still queued, the LED lights steadily
and queuing tone is heard again.
While waiting for a queued call, the user can place
and receive other calls.
● Callback
Callback applies only to stations that went on-hook after queuing was activated.
When the queued-for station becomes available to receive a queued call, the system
sends repeated priority ringing to the on-hook calling station. At a multiline set,
callback rings at the same SA button where the call to the queued-for station was
originally placed; the winking status LED of the button changes to flashing. The on-
hook station continues to get priority ringing until the callback is answered or until
the administered number of callback rings has been reached. When the original
calling station answers the callback, dequeuing tone is heard; this indicates that the
queued-for station will now be rung.
The calling user hears ringback until the
queued-for station answers.
An off-hook single-line set cannot receive callback until it is on-hook again. If a
multiline set is off-hook and active on another call when callback arrives, it receives
one cycle of priority ringing.
Administration sets the maximum number of callback attempts and the number of
rings per attempt. Each time a callback attempt for a given call is not answered, it is
counted against the assigned number.
If the last allowed callback goes unanswered,
the system cancels the queued call.
If a queued-for station becomes busy during callback and the calling station answers,
queuing tone is heard, not dequeuing; this callback attempt does not count against
the administered number. Another special situation exists when a multiline station
fails to answer a callback before ringing stops and the queued-for station remains
idle during the interval before another attempt. The multiline station can go off-hook
between callback attempts, press the queued button, and ring the idle queued-for
station.
