Queued Call Console
Barge-In allows the QCC operator to contact a person who is busy on
a call or using Do Not Disturb. Barge-In does not override Privacy.
On a QCC, Barge-In can be used only by pressing the Feature
button and selecting it from the display.
Barge-In can be used to join only an inside call to a QCC. The
caller's extension number must be dialed instead of the QCC
operator's extension number. If a user tries Barge-In after dialing a
QCC operator's extension (while waiting in the QCC queue), the
feature has no effect and the user hears an error tone. If the error
tone times out while the call is still in the QCC queue, the call is
disconnected. If the QCC operator becomes available before the
error tone times out, the error tone is removed and the call is
delivered to the QCC operator normally.
Calls to QCCs are not eligible for Callback because the calls ring into
the QCC queue. Callback cannot be used on a QCC.
Calling restrictions can be assigned to QCCs.
A QCC operator can release a call to a busy extension by selecting
from the display or by pressing the Release button. If
Camp On
Camp-On is used, the call does not return to the QCC queue until the
Camp-On return interval expires. If the operator presses the Release
button, the extension being called receives the call-waiting tone and
the call returns to the QCC queue when the transfer return interval
expires.
To use Camp-On when the system is programmed for automatic
Extended Call Completion, the operator must press the Start button,
dial the extension manually, then select
the QCC operator presses a DSS button, the transfer is completed
automatically and Camp-On cannot be used.
When a QCC operator arranges a conference call on a QCC, all
conference participants (a maximum of 5) are connected on one Call
button. This allows the QCC operator to put the conference on hold
and still have other Call buttons available to make or receive calls.
However, since all participants are on one Call button, the operator
can drop only the last person added to the conference by pressing
the Drop button and the Call button for the conference.
