2-186 Group Calling
When the QCC queue is assigned to provide overflow coverage for a calling
group, the following conditions must be met before calls are directed to the
QCC queue:
The number of calls in the calling group queue is equal to or greater than the
programmed threshold.
All QCC system operators are not in Position Busy mode.
An overflow call that is sent to the QCC queue does not return to the calling
group even if the call is not answered.
The Group Type setting determines whether or not the system automatically logs
in members of a calling group following a power failure.
The following settings are available:
Auto Logout — (the factory setting) This setting is used for calling groups to
specify that the system does not automatically login calling group members
after a power failure.
Auto Login — This setting is for calling groups used for fax machines or data
(also called "data hunt groups") to specify that the system automatically logs
in calling group members following a power failure. See the Data Guide for
more detailed information. The setting can also be used for calling groups
involving telephones.
Integrated VMI — This setting is used when a voice processing system (such
as AUDIX Voice Power - IS II or MERLIN MAIL™) that requires special
signaling for integrated operation is connected to one or more station jacks
assigned to a calling group. The system automatically logs in the calling
group members after a power failure.
Generic VMI — This setting is used when a voice processing system (such as
MERLIN Attendant or Integrated Voice Power Automated Attendant) that
does not require special signaling, is connected to one or more station jacks
assigned to a calling group. The system automatically logs in the calling
group members after a power failure.
Only a telephone assigned as a DLC can be a Calling Group Supervisor
Position. The supervisor must activate Extension Status to see the status of
calling group members and to change their availability; this cannot be done
from normal call handling operation.
To activate Extension Status, the calling group supervisor presses the Feature
button, dials 32, and presses the Hold button. To deactivate the feature and
return to normal call handling, the supervisor presses the Feature button, dials
32, and presses the Drop button.
