Queued Call Consoles
To arrange a conference call using a Queued Call Console (QCC), press the
Conf button after receiving a call or dialing the first outside number or
extension. The green LED next to the Call button flashes to indicate that the
person is on hold for the conference. An outside participant hears Music On
Hold if it is programmed; an inside participant hears nothing. Then dial the next
number and press the Conf button again; all participants are connected.
To add another person, press the Conf button again. The green LED next to the
Call button flashes, indicating a call on hold, and the participants can converse.
Add more participants by dialing their numbers and pressing the Conf button
until up to two outside lines and three extensions (including you, the originator)
are added. You can converse privately with each participant before pressing
the Conf button to join other participants.
Calls to busy numbers cannot be added to a conference. To disconnect a call
to a busy number, press the Call button with the conference call. Then continue
adding participants, if desired.
All conference participants are connected together on one Call button. This
allows you 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, by pressing the Drop button and the Call button used to originate the
conference, you can drop only the last party added to the conference.
To rejoin a held conference call, press the Call button with the conference
participant. To end the conference, join the conference and press the Forced
Release button; all participants are disconnected. If, instead of pressing the
Forced Release button, you hang up, the conference is put on hold.
When you arrange a 3-participant conference (yourself and two other
participants) and then press the Release button or hang up, you are released
from the call and the other two participants remain connected. If you arrange a
3- or 4-participant conference, pressing the Release button has no effect;
however, if you hang up, the conference is put on hold.
