A QCC system operator arranges a conference call by pressing the Conference
button after receiving a call or dialing the first outside number or extension. The
green LED next to the Call button flashes to indicate the person is on hold for
the conference. An outside participant hears Music-On-Hold if it is programmed;
an inside participant hears nothing. The QCC system operator then dials the
next number and presses Conference again; all participants, including the
originator, are connected.
To add another person, the QCC system operator presses the Conference
button again. The green LED next to the Call button flashes, indicating a call on
hold, and the participants can converse. The originator can continue to add
participants by dialing the number and pressing the Conference button until up
to two outside lines and three extensions (including the conference originator)
are added. The operator can converse privately with each participant before
pressing the Conference button to join other participants.
Calls to busy numbers cannot be added to a conference. To disconnect a call to
a busy number, the QCC system operator presses the Call button with the
conference call. This disconnects the call to the busy number. The system
operator can then continue adding participants.
All conference participants (a maximum of five) are connected together on one
Call button. This allows the system operator to put the conference on hold and
have other Call buttons available to make or receive other calls. However, since
all participants are on one Call button, the system operator can drop only the
last party added to the conference by pressing the Drop button and the Call
button used to originate the conference.
To rejoin a held conference call, the QCC system operator presses the Call
button with the conference participant. To end the conference, the QCC system
operator joins the conference and presses the Forced Release button, and all
participants are disconnected. If, instead of pressing the Forced Release
button, the system operator hangs up, the conference is put on hold.
When a QCC system operator arranges a three-participant conference (the
system operator and two other participants) and then presses the Release
button or hangs up, the QCC system operator is released from the call and the
other two participants remain connected. If the system operator arranges a
three or four-participant conference, pressing the Release button has no effect
however, if the system operator hangs up, the conference is disconnected.
A multiline telephone user arranges a conference call by pressing the
Conference button after receiving a call or dialing the first outside number or
extension. The green LED next to the button used to make the call flashes to
indicate the person is on hold for the conference. An outside participant hears
Music-On-Hold if it is programmed, and an inside participant hears nothing. The
user then selects another line button, dials the next number, and presses
Conference again. When the Conference button is pressed the second time, all
participants (including the originator) are connected.
