Configuration Settings: E911 System
5.24.2 Zones
Zones are used for Dial Emergency calls on US systems when a trunk to the E911 adjunct cannot be seized or the E911
adjunct is indicating an alarm through its alarm station being off-hook (busy).
Zones allow extensions in the same location to be grouped and to have the external trunks registered to the same
location associated with them. This billing address of those trunks or other information held by the trunk provider can
then be used to identify the correct emergency center that should respond to Dial Emergency calls from extensions in
that zone.
The extension number used for this function is the Base Extension number set through the Extension | Extn tab.
This allows the physical extension to be correctly identified even if currently being used by a hot desking user with a
different associated extension number.
A zone named Default is maintained by the system. By default all extensions and lines are included in this zone. This
zone can be edited but cannot be removed. Any extension included in another zone and then removed is automatically
placed back into the Default zone. Trunks can be deleted as some trunks will not be public trunks suitable for emergency
calls.
· To call an extension using its Base Extension number, the short code feature Dial Physical Extn by Number
can be used. This is normally provided by the default short code *70*N# when N can be replaced by the
required Base Extension number.
Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
This tab shows the existing E911 zones, the number of stations (extensions) and trunks in each zone and the base
extension numbers of the extensions. The settings can be edited by clicking on an existing zone and selecting Edit. A
new zone can be created by selecting Add.
· Name: Default = Default. Range = Up to 15 characters.
Allows a unique name to be assigned to each zone.
· Stations: Default = Contains all Extension ID's
Lists the extensions in the zone. Click Add to add and remove extensions. To just remove extensions, select the
extension or extensions and click Remove. Extensions removed from any zone are automatically included in the
Default zone and cannot be removed from that zone except by inclusion in another zone. Each extension can only
be included in one zone.
· Trunks: Default = Blank
List the trunks associated with the zone. Click Add to add and remove trunks. To just remove trunks, select the
trunk or trunks and click Remove. Each trunk can only be included in one zone. Dial emergency calls will seize the
first available trunk. If no available trunk can be seized, the call will fallback to using the routing indicated with the
Line Group ID of the Dial Emergency short code and final to using any available analog or digital trunk.
