Page Zones
The Page Zone feature allows you to designate a subset of devices within
the system as members of a zone. Telephone users then can page
members of that group only, rather than paging all devices on the system.
The system supports up to 16 page zones per system.
The system allows multiple simultaneous zone pages. However, a device
that is currently paging or being paged will not respond to another page
request.
A Page Zone extension must be in the external device extension range:
■
6000-7999 for a 4-digit dial plan
■
600-799 for a 3-digit dial plan
The default 3- and 4-digit dial plans assign extension numbers that start
with 7 as diagnostic. Diagnostics is a Class of Service that you can assign
to a telephone user. For example, if you want to assign a page zone to
extension 720, either change the dial plan (to make 7** an internal call)
or assign the CoS permissions labelled Diagnostics to users who will be
dialing the 720 page zone. To keep the dial plan and CoS defaults, use
the extension range of 6000 – 6999 (or 600 – 699) for page zones.
Many extensions in these ranges are already reserved for Call Park and
other features. Typically, you choose an extension near the upper end of
the external extension range. Click
Reports > Device List for a list of
extensions currently in use.
Page Zone Feature
Support
The Page Zone feature supports the following features and desktop
applications:
■
Caller ID — The display panel on the device originating the zone page
displays the zone page’s name and extension; the recipients’ display
panels do not display the broadcaster’s extension.
■
Hands Free — A zone page reaches a device that has Hands Free
enabled.
■
Hold — A zone page reaches a device that has Hold enabled.
