MERLIN LEGEND Communications System Release 6.1
Feature Reference 555-661-110
Features
Conference
!
SECURITYlALERT:
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 people often use the Conference feature, 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. However, the
LED for the original conference call line on the SA or ICOM button 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 a user has added two outside calls to a conference,
it is not possible to 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.
Mode Differences
Behind Switch Mode
The fixed Conf button on multiline telephones activates conference from the host
system. The dial codes for the host system for Conference and Drop must be
system-programmed. A multiline telephone user can program a Conference or
Drop button to use the communications system's Conference or Drop features as
described above.
A single-line telephone user cannot use the Conference feature in Behind Switch
mode.
