E911 System

IP Office supports Enhanced 911 (E911) service that allows the recipient of 911 calls to accurately identify the telephone number and physical location of the calling party. Emergency personnel cross-check the incoming Automatic Number Identification (ANI) with the Automatic Line Identification (ALI) or billing information (in other words, the billing address) associated with the telephone number. If the caller is in a multi-floor office or multi-billing campus, emergency operators have little idea of the exact location of the caller since the information presented is often just the main billing address of the company. You can use the E911 zones in combination with E911 adjuncts to provide more specific ALI about the caller's location.

As a building can be partitioned into different floors or different areas on one floor, the extensions in IP Office can be grouped ("zoned") according to their locations. For example you can place all the extensions in the Northeast Corner of the building in one zone and the extensions in the Northwest Corner in another zone. You can then assign some trunks with ALI of the Northeast Corner to the first zone and trunks with ALI of the Northwest Corner to the second zone. When a caller dials "911", the ALI information shows the emergency response team exactly where the caller is located.

If your states requires that dialing the access code (ie. "9") in front of "911" also allow the call to go out, add the following System Short Code:

Short Code: 9911
Telephone Number: 911
Line Group ID: 0
Feature: Dial

The following options are only available in regions where E911 is supported (it is available in the United States). The configuration consists of an E911 System entry (shown by the icon) and ten E911 partitions (shown by icons). The IP Office E911 solution requires that Analog Loop Start lines be used for all trunks that are used for Adjuncts (see System Parameters) and Zones (see E911 Zone Configuration ).
