Group Calls (Conference)
Group calls are conference calls for up to 100 participants. Each Group Call has a unique dial number. Group Call
members can be internal stations or external numbers dialed through Public Library numbers. There are two types of
group calls:
•
Preset
Group Calls have pre-defined members
•
Temporary
(Add-On) Group Calls have no predefined members; the Group Call initiator adds participants
Participants in group calls include the group call operator (controller), the group call initiator (usually responsible for
subject matter and discussion), and the other group call members.
Signals heard during a group call depend on the system settings. Optional signal include a warning tone heard by the
conference initiator when activating the group call and a signal heard by all participant every time a participant joins or
leaves an ongoing conference call. When a Group Call is placed, all stations defined as registered members for that
particular group ring. Unanswered stations continue to ring until a pre-defined timeout period expires.
Participation in group calls can be limited by:
•
Blocking group members from joining after the ringing has stopped
•
Blocking users that are not registered to the group call (locking the call)
There are two ways in which non-registered users can join non-locked group calls:
•
A non-registered user can dial the access number
•
A registered user can connect the non-registered user to the group call.
The Group Operator has the option of controlling the Mute / Non-Mute mode of conference participation of each
participant. Mute mode means the participant may only listen. Typically, a conference initiator might initiate a muted
conference in which only the conference initiator can speak; during the conference, the Group Operator can grant
permission to individual participants to speak.
Group Call options are set in the Group Call definitions. A user can be authorized to force release a participant or
terminate an entire conference.
