Department Calling
n Description
With Department Calling, an extension user can call an idle extension within a pre-programmed
Department Group by dialling the group's pilot number. The call would ring the first available
extension in the group. For example, this would let a caller dial the Sales department just by knowing
the Sales department's pilot number. The caller would not have to know any of the Sales department's
extension numbers. The system allows up to 32 Department Calling Groups.
Department Group Name
When an internal extension is queued at a busy department group the name will be displayed at the
system phone's display. The user will see: WAITING (group name). The group name is set by Program
16-01-01.
Department Group Routing
There are two types of routing available with Department Calling: Priority Routing and Circular
Routing.
With Priority Routing, an incoming call routes to the highest priority extensions first. Lower priority
extensions ring only if all higher priority extensions are busy. Priority routing is selected by Program
16-01-02.
With Circular Routing, each call rings a new extension, providing an easy type of Uniform Call
Distribution (UCD).
For example, in a Department Group set for circular routing with extensions 210 (Priority 1), 211
(Priority 2) and 212 (Priority 3).
·
The first call rings 210.
·
The second call rings 211.
·
The third call rings 212.
·
The fourth call rings 210 and the cycle repeats.
Note: When programming, the high priority extensions have low priority numbers. For example,
priority 1 has a higher priority than priority 10.
Overflow Routing
Department Calling also provides overflow routing for extensions within the group. If a user directly
dials a busy extension within a Department Group, the system can optionally route the call to the first
available group member. Overflow routing is set by Program 16-01-03.
Hunting Mode
Ringing calls can step around members of the group once only and stop at the last member or
repeatedly search for a free member. Hunting mode is set by Program 16-01-04.
Simultaneous Ringing
All idle members of the department group can ring simultaneously for internal and outside calls to the
pilot number. Calls do not cycle between group members. Simultaneous ringing can be automatic (all
members ring when the call is placed to the pilot number) or manual ( the call to the pilot number will
step around each member of the group until the caller selects simultaneous ring mode). The
automatic/manual option is selected by Program 16-01-05. To select manual mode the user must either
dial the service code 780 (set by Program 11-12-09) or the single digit service code set by Program
11-16-10.
Note, when automatic is selected the operation of Program 16-01-10 is effected. Calls to the pilot
number will not receive ringback tone if all members are busy, they will receive busy tone and will not
wait for a member to become free.
Recall Restriction
Calls transferred to the pilot number that do not get answered will recall at the extension that
