Barge-In can be used to interrupt conference calls; all participants hear
the Barge-In tone. Barge-In, however, does not connect the user to a
conference call if the conference already has the maximum number of
participants. If Barge-In is used to connect to a conference call that
involves an outside line/trunk and the person on the outside line/trunk
hangs up, the person using Barge-In is also dropped.
Calls on BRI lines can be part of a conference call that is processed by
the MERLIN LEGEND Communications System rather than by the central
office (CO). The MERLIN LEGEND Communications System determines
the number of active parties on the call.
The MERLIN LEGEND Communications System supports up to five
people on a conference: two within the system, two outside the system,
and the call originator.
If a MERLIN LEGEND Communications System user is part of a
conference established by an outside party through the central office
conference feature, the MERLIN LEGEND Communications System may
play Music On Hold (if so programmed) when the MERLIN LEGEND
Communications System user puts the call on hold.
A call-waiting tone is heard only by the person receiving the call and not
by other conference participants. If the conference originator reaches a
busy extension, hears the call-waiting special ringback, and tries to add
the call to the conference, the system returns a busy tone. To drop the
busy tone from the conference, the originator must press the Drop button
and then press the line button used to call the busy extension.
A queued call cannot be part of a conference. With Automatic Callback,
the call is automatically queued; however, if you try to add the queued call
to the conference, the system returns a busy tone. If you use Selective
Callback to queue a call while setting up a conference, the system returns
a busy tone. Press the Drop button and the line button with the queued
call to drop the busy tone from the conference.
The conference originator can view Caller ID information associated with
any participant by pressing the Inspct button and the button the caller is
on.
A user with an outward-restricted extension cannot add an outside
participant to a conference unless the participant's number is on an
Allowed List assigned to the extension. A user with a toll-restricted
extension cannot dial a toll number to add a participant unless the
participant's number is on an Allowed List assigned to the extension.
You cannot add an outside number to a conference if the number is on a
Disallowed List assigned to your extension.
You can originate a conference call from a Cover button only when you
press the Transfer button, dial the number for another person, and then
press the Conf button to complete the transfer. In this case only, instead
of the call being transferred, a conference call with three participants
(including the originator) is established.
