Feature Reference
QCC Queue Overflow Receiver
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 must be equal to or
greater than the programmed overflow threshold.
No QCC operators can have Position Busy on.
An overflow call that is sent to the QCC queue does not normally return to the
calling group even if the call is not answered. If all QCCs have Position Busy
active, the calls from the calling group do not overflow, and continue to wait in the
calling group queue. If all QCC operators activate Position Busy while an overflow
call is in the QCC queue, the call is rerouted to the original calling group.
Calling Group Type
The Group Type setting determines whether or not the system automatically
logs in members of a calling group following a power failure. The setting also
determines the type of voice messaging interface (VMI) when the calling group
is used to connect voice messaging systems or automated attendant
applications. The following settings are available:
Auto Logout. This setting is used to specify that the system does not
automatically log in calling group members after a power failure. When
the Group Type is set to Auto Logout (the factory setting) and a call sent
to a calling group member is not answered within 30 seconds (5 rings),
the call is sent to another member, or to the front of the queue if no
calling group member is available.
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.
Auto Login can be set for calling groups used for telephones.
Integrated VMI. This setting is used when a voice messaging system
(such as AUDIX Voice Power, or MERLIN MAIL) that requires special
signaling for integrated operation is connected to one or more extension
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 messaging system (such
as AT&T Attendant or Integrated Voice Power Automated Attendant) that
does not require special signaling is connected to one or more extension
jacks assigned to a calling group. The system automatically logs in the
calling group members after a power failure.
Considerations and Constraints
An extension can be a member of only one calling group. Calling groups with no
members are allowed.
