Features
Group Calling
Message-Waiting Receiver
The message-waiting receiver is the extension designated to receive
message-waiting indications for the calling group. This includes message-waiting
indications sent from an operator, from a display telephone using Leave Message,
or from a fax machine. Any type of telephone with a message LED can be
assigned as a message-waiting receiver.
NOTE:
In Release 6.0 and later systems (Hybrid/PBX mode only), a remote
extension cannot provide message-waiting services for a local calling
group.
The extension designated as the message-waiting receiver does not have to be a
member of the calling group. Each calling group can have only one extension
assigned as its message-waiting receiver; the same extension can be assigned
as the message-waiting receiver for more than one calling group.
Message-waiting indications cannot be sent to the extension number assigned to
the group unless this option is programmed. The message-waiting receiver
cannot distinguish between messages left for the calling group and personal
messages.
Calls-in-Queue Alarm Threshold
The Calls-in-Queue Alarm Threshold is the number of calls (1–99) allowed in the
queue before calling group supervisors and members are notified that too many
calls are waiting for attention. In Release 5.0 and later systems, the system
manager can assign three threshold levels to indicate increasing levels of
severity, as explained later in this section. When the number of waiting calls is
equal to or greater than the programmed Calls-in-Queue Alarm Threshold setting
(factory default is one call), the calling group members can be notified in either of
two ways:
Through an external alert connected to an MLX telephone by using a
Multi-Function Module (MFM); the MFM is set for Supplemental Alert
Adapter (SAA) operation and programmed as the alert. Because the tone
sent to the alert is continuous, only a device such as a strobe light, which
stays lit until the number of calls drops below the limit, should be used.
Only one external alert can be assigned to each calling group, and each
external alert can be assigned to only one calling group. An SAA should
not be used with an analog multiline telephone, because a steady tone is
emitted from the telephone when the visual alert is on.
The system does not block the programming of any extension jack
(including extension jacks used for telephones or operator consoles) as an
external alert to provide the calls-in-queue alarm. Programming a
telephone or console extension as a calls-in-queue alarm, however, is not
