Group Calls (Conference)
Group Calls, each with its unique dial number, are conference calls allowing participation of up to 250 participants at a
time. Group Call members can be internal stations or external numbers via Public Library numbers.
Two different types of Group Calls are offered:
•
Preset
Group Calls comprised of pre-defined members
•
Temporary
(Add-On) Group Calls containing no predefined members, where participants are added by the Group Call
initiator.
When a Group Call is placed, all member stations 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 continue ringing until the defined time-out period expires, 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 a 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 the user defined as the
Group Operator
.
Participants may join a conference with the ability to speak, or they may join in the mute mode in which they can only hear
others allowed to speak. 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.
