Group Calls
Group Calls
Group Calls are conference calls, allowing participation of up to 100 members at a time. Two options are offered:
•
Preset Group Calls comprised of predefined members
•
Add On (Temporary) Group Calls containing no predefined members, where participants are added from the Group Call
initiator station
Each Group Call has its own unique dial number. Group Call members can be internal stations or external numbers dialled
through Public Library numbers.
When a Group Call is placed, all stations defined as registered members for that particular group ring. As a member joins the
conference (i.e. answers the incoming group call ring), all actively participating members can be alerted by a defined warning
tone. Unanswered stations will continue ringing until the defined timeout period is completed, without disturbing the
conference.
Depending on the system settings, a warning tone may be heard by a conference initiator upon activating the group call, and
by all the participants every time a participant joins (or leaves) an ongoing conference. Group members may be blocked from
joining the conference once the ringing has stopped. The conference may, if desired, be locked to those users that are not
listed on the system as the conference registered members. When the Group Call is not locked, the non-registered members
may join an ongoing conference by dialing the Group Call access code, or be connected by a registered member.
The conference is controlled by a user defined as the
Group Operator
.
Participants may join a conference with the ability to speak and hear each other, or in the
Mute
mode to only hear other group
members. In case of a muted conference, only the Group Call initiator has the right to speak. Other participants can be granted
permission to speak by the
Group Operator
. These options are set in the Group Call definitions. An authorized user can force
release a participant or terminate an entire conference.
