Queued Call Console
When a conference participant joins a conference call by using a
shared outside line or a Shared SA button, the QCC display reflects
the correct number of participants. However, if the QCC operator
uses the Inspect feature to verify the number of participants, the
number shown on the display does not include participants joining
the conference call on Shared SA buttons. Pressing any of the
buttons programmed with fixed QCC features (for example, a Call,
Start, or Source button) while in Inspect mode does not remove the
console from Inspect mode. However, pressing the Feature,
Transfer, HFAI, Conf, Drop, Speaker, or Hold button does remove
the console from Inspect mode.
Last Number Dial cannot be used on a QCC.
Line Request cannot be used on a QCC.
A QCC operator can use Leave Message only by selecting the
feature from the display. A Send/Remove Message button is
programmed as a fixed feature on a QCC.
The microphone on a QCC is automatically disabled and cannot be
enabled.
An MFM cannot be connected to an MLX-20L telephone assigned as
a QCC. As a result, adjuncts such as answering machines and fax
machines cannot be used with the console.
A Night Service button is assigned as a fixed feature on a QCC.
If more than one QCC operator is assigned to receive calls on an
individual trunk, Night Service must be turned on at all assigned
positions before calls coming in on the trunk can ring on extensions
programmed as members of the Night Service group. If Night Service
is not turned on at QCC position programmed to receive the calls,
after-hours calls ring at that position and do not receive Night Service
treatment. When Night Service is on, unassigned DID extension and
Listed Directory Number call types ring into the QCC queue, and this
cannot be changed. If these call types are programmed not to go to
the queue, callers hear an error tone when Night Service is off.
When multiple Night Service calls are received in the QCC queue at
the same time and none of the calls are answered by a Night Service
member (all group member ICOM or SA buttons are busy), new calls
are sent to the QCC queue and can be answered only by the QCC
operator. To avoid this situation, all outside lines assigned to ring in
to the QCC queue should be assigned as personal lines on at least
one group member's extension.
