Calling group agents with MLX display telephones see feedback messages on
the display when they log into the Available state. When a calling group
supervisor with an MLX display telephone logs calling group members in or out,
a message appears on the supervisor display and on the group member's
display. After pressing either the Available or unavailable button or dialing the
feature code, supervisors with MLX telephones are prompted to indicate which
group member they want to log in or out. When a calling group member with an
MLX telephone receives an outside call for the calling group, the type of call is
identified on the display along with the label for the line the call came in on. If
automatic number identification (ANI) is available, the number of the caller is
shown on page 2 on MLX telephones. Analog multiline telephone users see only
the line information. Any MLX telephone user can inspect the number of calls in
queue by pressing Inspect and then pressing a button programmed with the
calling group's extension. The display shows the label associated with the
calling group and the number of calls.
If a calling group member uses Do Not Disturb, calls are not sent to the group
member even if he or she is logged in and available.
Extension Status allows calling group supervisors to change and monitor calling
group member status, and enable group members to sign in and out of the
calling group.
An available calling group member is automatically logged out when calls are
forwarded to an extension or telephone number. If a calling group member logs
in while calls are being forwarded, Forward or Remote Call Forward are
automatically canceled. Calls cannot be forwarded to calling groups.
When a line/trunk is assigned as a personal line on a station assigned as a
principal user and the line/trunk is also programmed to ring into a calling group,
an incoming call received on the personal line is not sent to the calling group if
the principal user forwards calls to an outside telephone number using Remote
Call Forwarding.
A calling group member who put a call on hold by using the Hold button is
considered unavailable for incoming calls. A user waiting in the calling group
queue cannot put the call on hold.
An alphanumeric label can be assigned to the calling group. The label is
displayed only when an MLX display telephone user presses the inspect button
and an Auto Dial button programmed with the calling group's extension number.
Users can leave messages for the calling group only if the system has been
programmed with a designated Calling Group Message Receiver. The receiver
also receives fax message-waiting indications directed to the calling group. The
message-waiting receiver cannot distinguish between messages left for the
calling group and fax or personal messages.
