911 Enhancements
Release 9 replaces the legacy E911 feature with new functionality to handle the routing and notification of Emergency call based on new Location configuration objects. Support for legacy E911 add-ons is removed from IP Office R9.0.
• Dial Emergency Call Routing: On matching a Dial Emergency short code, the system will initially try to find the best matching Locations which contains an ARS to determine which line to use. In priority order this will be: Location exactly matching Extensions location; System location. If neither locations resolve an ARS record, then the fallback is provided by line group ID and the Dial Emergency short code (as in previous releases).
• Emergency Call System Alarms: Emergency Calls is a system event that can be added into the Systems Events configuration.
• Information provided by the system raises an Emergency Call Alarm:
» Success/Failure to place the call
» Cause (Failed calls only)
» Default Extension number (Base Extension)
» Caller Type dependent identifier: TDM Port ID, IP address, Telecommuter/Mobility phone number, Trunk SCN/Tand
» Location Name
