Group Calls
Group Calls
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 dialled through Public Library numbers. There are two types of group calls:
•
Preset Group Calls have predefined members
•
Add On (Temporary) 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.
