7-6 ROLMphone 300/600 Series User Guide
You can only join a station hunt group if your phone has been assigned
the station hunt group class of service. (Ask your system administrator
whether your phone has it.) You can only be a member of one station
hunt group. However, other linear-pattern hunt groups may include
you as the last member of their groups. (See “Linear Pattern” on page
7-6.)
A call to a station hunt group can be made initially to any group
member, since a station hunt group does not have a pilot extension.
Hunting Patterns
If hunt destinations are set up so that the first member becomes the
destination of the last member, a circular pattern is formed. If hunt
destinations are set up so that the last member has no further
destination, a linear pattern is formed.
Circular Pattern
In a circular pattern, a call will advance from busy phones, or from
ringing phones with No-Answer Advance, until every phone in the
group has been checked once.
For a circular-pattern pilot hunt group, if all the members of the group
are busy the call will then be placed in a queue until one of the
members becomes available. If no system queue has been set up at the
communications server, or if all queue positions are occupied, the
caller will receive a busy tone.
For a circular-pattern station hunt group, after the initial round of
advancing the call will be automatically queued at the phone that was
originally called. If this is not possible because there is already a call
waiting, or because the class of service of the phone to which the call
was originally directed does not allow automatic queuing, the caller
will receive a busy tone. If a call advances to the final member in the
group, that phone will continue ringing until the beginning member is
idle and will then advance to the beginning member.
Linear Pattern
In a linear pattern, a call will advance from busy phones, or from
ringing phones with No-Answer Advance, until it reaches the phone
set up as the last member in the group and will not advance after that
to the phone set up as the first member.
