E911 Zone Configuration

Zones allow stations to be grouped together that have a similar physical location. Lines are then assigned to the partition. This billing address associated with the lines can be used to locate the caller. For E911, what needs to get out is the actual phone that a person is calling from. In the case of IP Office, Hot Desking allows multiple users to use a single phone (at different times � See Extension versus User ). For that reason, it is important to understand that it is the default User ID that gets sent out, no matter what user is currently "logged in" to that extension. This allows the physical extension number to be associated (via an external database) to a specific address (i.e. room number). The Extension form will provide the information about default users for each extension. In an IP403, the following is the default for the extensions on the Control Unit:

With the above numbering, when a person was using the phone connected to Extension ID 67, "203" would be sent out regardless of the extension number associated with the user currently logged into that station. A person would be able to dial the phone by using either of the following short codes (these are the defaults).

• DialPhysicalExtnByNumber (default short code *70*N# � where "N" is the default User ID for the extension). This allows the user to call the default user id no matter who is currently using that station. Using the numbers from the table above, if a user with an extension number 505 was currently logged into physical extension 67, they could always be called by dialing "*70*203#".

• DialPhysicalExtnByID (default short code *71*N# � where "N" is the default extension ID for the extension). This allows the user to call the default user id no matter who is currently using that station. Using the numbers from the table above, if a user with an extension number 505 was currently logged into physical extension 67, they could always be called by dialing "*71*67#".

It is expected that the first short code will be used more often due to the fact that the number that gets sent out will be the extension number not the physical ID.

Double-clicking on the icon expands and collapses the display of E911 zones ( icons). Click on any icon to display details of the partitions in the right-hand panel.

Double-click on the icon to edit the zone settings. Alternatively, in the right-hand panel, right-click and select the option required (View, Edit, New or Delete).

• Name: Default = Default
  Allows a unique name to be assigned to each zone.

• Stations: Default = Contains all Extension ID's
  Lists the extensions id's within the partition. Right-click on the list to add or delete entries. An extension can only be in one zone, so when you add an extension it is automatically removed from it previous assignment. When adding stations, the Selecting E911 Stations form appears listing available stations and the partition to which they are currently assigned.

• Trunks: Default = Blank
  List the Analog Loop Start trunks within the partition. Right-click on the list to add or delete entries. When adding trunks, the Selecting E911 Trunks form appears listing all available trunks and the partition to which they are currently assigned. Only reliable Analog Loop Start trunks should be used.
