Features
Dropping Conference Participants
A multiline telephone user can selectively drop conference participants while
the conference is in progress by using the Drop button. However, a QCC
system operator cannot selectively drop participants from a conference. When
the QCC system operator presses the Drop button, only the most recently
added participant is dropped. Single-line telephone users can drop the most
recently added participant from the conference by pressing and releasing the
switchhook.
Leaving a Conference
The conference originator can leave the conference by pressing the Hold
button (the conference continues). If a conference originator (excluding a QCC
system operator) leaves a conference by either hanging up or selecting another
line, the entire conference is disconnected.
Considerations and Constraints
Transmission quality may vary during the conferencing of outside lines.
A call to a busy number cannot be added to a conference.
Pressing the Drop button and the line button for a participant also disconnects
a participant who joined the conference by using a shared outside line or an SA
or ICOM button.
When a conference originator puts the conference on hold, Music-on-Hold is not
activated.
Beginning with Release 1.1, the system automatically selects an SA or ICOM
button when the user presses the CONF button. In Release 1.0, the system
does not automatically select an SA or ICOM button; the user must select the
line manually.
In addition, beginning with Release 1.1, systems use prompting to help the MLX
display telephone user set up a conference call. When the user presses the
Conference button, one of the following happens:
■ If the system is in Hybrid/PBX mode and the user has an available SA
button, the system automatically selects one in the following order of
preference:
— SA Originate Only (Ring)
— SA Originate Only (Voice)
— SA Ring
— SA Voice
