Features
Conference
NOTE:
Conference and Drop buttons are available in all modes; they are
programmable only in Behind Switch mode.
Adding Conference Participants
A user can consult privately with each participant before adding the person to the
conference. Anyone who shares a personal line or Shared SA button with the
originator can join the conference on that button and is counted as a participant.
Dropping Conference Participants
By using the Drop button, a multiline telephone user can selectively drop
conference participants while the conference is in progress. However, a QCC
operator cannot selectively drop participants from a conference. When a QCC
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 issuing a switchhook flash.
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 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 personal line or an SA or
ICOM button.
When a conference originator puts the conference on hold, Music On Hold is not
activated.
In Release 1.1 and later systems, the system automatically selects an SA or
ICOM button when a user presses the Conf button. In Release 1.0 systems, the
system does not automatically select an SA or ICOM button; the user must select
the line manually.
