MERLIN LEGEND Communications System Release 7.0
Feature Reference 555-670-110
Features
Conference
After the system selects an SA button or the originator selects a line on an MLX
display telephone, Line 2 displays the prompt Dial. The originator can either dial
a number or select another line. Line 1 shows call-handling information, such as
dialed digits, while Line 2 is unchanged. The originator should then press Conf to
connect all parties. The prompt on Line 2 is replaced by the date and time. Line 1
displays the number of parties in the conference.

SECURITY ALERT:
If the system selects a voice button, the caller hears a beep instead of
ringing. If a person does not answer at the destination extension and the
originator completes the conference, the conversation of the other parties is
broadcast on that extension's speaker. The originator must be sure to drop
the unanswered destination extension on a voice button to prevent this from
happening. If the Conference feature is frequently used, the system
manager should consider using the Transfer Type setting of Ring rather
than Voice, to avoid this problem.
If the conference originator presses the Conf button, selects a line button, dials a
number, and presses the Conf button again before the person being called
answers, all conference participants hear ringback, which may cause voices to cut
in and out. If the conference originator calls a co-worker and presses the Conf
button, and the co-worker while on hold for the conference presses a Hold, Conf,
or Transfer button, the call is disconnected.
If a conference participant (excluding the originator) who is included on a
conference call on an SA or ICOM button leaves the conference temporarily by
putting the call on hold and then rejoins the conference on a shared personal line
or Shared SA button, the person is connected to the conference. The LED for the
original conference call line on the SA or ICOM button, however, turns off.
In Release 2.1 and later systems, a call on hold at a programmed Cover button
can be added to a conference by an originator with a personal line for the call.
In Release 6.0 and later systems (Hybrid/PBX mode only), calls to non-local dial
plan extensions are treated as outside calls for the purpose of conferencing. Each
non-local conference participant takes up one of the two outside calls permitted in
a conference. For example, if you have added two outside calls to a conference,
you cannot add a non-local extension. Similarly, if two outside parties are already
participating in a conference, and an attempt is made to add a third participant on
the local switch, the local user can be added if he or she answers the call.
