Station Group
Stations can be grouped so incoming calls may be routed to an idle station in the group. The
different types of Station Groups are described:
• Terminal Group – Calls to a station in a Terminal Station Group that encounter an
unavailable or go unanswered will be routed through the hunt process. The call will
proceed to the next listed station in the group until reaching the last listed station. The
queued call may be taken out of the group if set to forward to an overflow destination.
• Circular Group – Calls to a station in the Circular Group will go to the station, if
unavailable or unanswered in the hunt no answer time; the call will be directed to the
next station defined in the group. The call will continue to hunt until each station in the
group has been tried. The queued call may be taken out of the group if set to forward
to an overflow destination.
• Ring Group – An incoming call to any station in the Group will cause all stations in the
group to ring, and any station in the group may answer the call. Multiple calls can be
received by a Station Ring Group and can be serviced in any order according to
Station availability. The queued call may be taken out of the group if set to forward to
an overflow destination.
• Longest Idle (UCD) Group – Calls are sent to the group by dialing the Hunt group
Number or assigning CO lines to directly terminate at the group. Calls are directed to
the Station in the group that has been idle for the longest time. If all stations in the
group are busy when a call is received for the group, the call may be routed to an
alternate location, or may continue to wait (queue) for a station in the group to become
available. The queued call may be taken out of the group if set to forward to an
overflow destination.
• Station VM Group – Can be enabled to support an external Auto Attendant/Voice Mail
(AA/VM) system that employs SLT ports to interface with the system. An External
AA/VM group is assigned for either Circular, Terminal, or Longest Idle hunt. The
External AA/VM may employ either in-band signaling over the audio channel or SMDI
protocol with a signaling connection to the System RS-232 channel.
