Applications
Night Service
If the Automated Attendant handles only after-hours calls, a phantom
station (an unused station jack) must be programmed as a member of a
Night Service group associated with a system operator. In turn, this
phantom station is covered by a calling group with integrated VMI ports
as members. If an incoming call is not answered within the programmed
number of rings, the control unit sends it to the calling group with the VMI
ports. AUDIX Voice Power must be programmed to recognize the call to
be from the phantom station, and provides Automated Attendant service
rather than the usual Call Answer service.
SMDR
CAS collects call information from the SMDR output of the system.
System Renumbering
System Renumbering can be done only via SPM or MLX-20L system
programming. Integrated Administration uses System Renumbering to
read extension numbers and adjuncts.
Transfer
Integrated VMI ports can transfer an incoming call to an outgoing
line/trunk.
If a caller incorrectly specifies the answering VMI port as the desired
transfer destination station, the VMI port may park the call.
Any calling group, calling group member, or extension can be
programmed to be a VMS transfer redirect extension. If a QCC is so
programmed, the transfer redirect call is delivered to the QCC as a
returning call and is not placed in the QCC queue.
If a transferred caller gets no answer and returns via Voice Mail to the
system operator, the system operator has no indication of the origin of
the call.
System Programming
The following system programming is required for AUDIX Voice Power:
Assign AUDIX Voice Power ports to a calling group and specify the
group type as VMI Integrated.
Program each VMI loop-start port for reliable far-end disconnect.
Specify the touch-tone duration and interval between digits in codes sent
between AUDIX Voice Power and the system.
Specify the number of rings before a call transferred by AUDIX Voice
Power is sent to the backup position (system operator).
