Station Hunting
A series of Directory Numbers (DNs) can be organized in groups in such a way that if a called
[DN] is busy the call will try to ring another [DN] in the group. If that [DN] is busy it will hunt to
a third [DN], etc. Telephones in the same department, voice mail ports and boss/secretary call
coverage situations are typical applications for hunt groups. Hunt group members can remove
themselves from the group by placing their station into the Do Not Disturb mode. The system
supports three types of station hunting:
Serial Hunting
In this type of hunt group, calls hunt [DNs] in a series from first to last in a specific order. When
any [DN] in the series is called, the system will ring the first idle [DN] in the series, starting with
the called [DN], hunting to the last [DN] in the series. As an option, this type of hunt group can
have a unique Pilot [DN] assigned to it. When callers dial the Pilot [DN] to reach a telephone in
the group, calls will hunt all [DNs] from first to last.
Circular Hunting
In this type of hunt group, calls hunt [DNs] in a series in a specific order; however, the series forms
a loop, which enables the last [DN] to hunt to the first [DN]. When any [DN] in the series is called,
the system will ring the first idle [DN] in the series, starting with the called [DN], hunting to all
[DNs] in the series. As an option, this type of hunt group can have a unique Pilot [DN] assigned to
it. When callers dial the Pilot [DN] to reach a telephone in the group, calls will hunt all [DNs] from
first to last.
Distributed Hunting
This type of hunt group always has a unique Pilot [DN] assigned to it. Callers dial the pilot [DN] to
reach a telephone in the group. Calls hunt in such a way so as to distribute the calls evenly to each
[DN] in the group. Hunting rotation always starts in sequence with the [DN] that follows the [DN]
that received the last call – even if all other [DNs] are idle.
Camp on to Hunt Groups
On incoming CO line calls to busy hunt groups, the caller automatically camps on to the called
[DN] or Pilot [DN] and the caller receives ring-back-tone.
On internal calls to busy hunt groups, the caller may get busy tone. The caller can then dial a digit
to initiate Camp On-Busy to the called, busy [DN] or the Pilot [DN], if used. As an option, for
each hunt group that uses a Pilot [DN], calls will automatically camp on to the called Pilot [DN].
With the Automatic Camp On option, the caller does not get busy tone, instead the caller receives
confirmation tone followed by ring-back-tone. When using hunt group Pilot [DNs], camped on
calls queue onto all [DNs] in the group and will connect to any [DN] in the group that becomes
available. When not using Pilot DNs, Camp On is only applied to the called [DN].
When more than one party is camped on (queued) to a hunt group, the party with the highest
Queuing Priority Level (QPL) will be connected first when the destination becomes available. If
the parties have the same QPL, the longest waiting call will be connected first.
