• Location ID 3 – Sunnyvale
• Location ID 4 – Los Gatos
Another organization may choose to create different E911 Location IDs for each floor of a large office building,
similar to this approach:
• Location ID 1 – Basement/garage
• Location ID 2 – Floor 1
• Location ID 3 – Floor 2
• Location ID 4 – Floor 3
Yet another schema could be to implement E911 Location IDs by the type of use of various building sections, by
floor, similar to the following method. This convention uses the first digit as the floor and the second digit as an
area within that floor.
• Location ID 11 – Warehouse
• Location ID 12 – Floor 1 Lab 1
• Location ID 13 – Floor 1 Lab 2
• Location ID 14 – Floor 1 Shipping
• Location ID 15 – Floor 1 Manufacturing
• Location ID 21 – Floor 2 Test Lab
• Location ID 22 – Floor 2 Imaging
What’s important is to come up with a set of entries that works for you, based upon your type of organization and
your geographic specifics.
E911 Hierarchy
The system follows this hierarchy to retrieve E911 information when a user places a 911 call from an IP phone:
1. The system will transmit the information in the E911 Location ID entry that is assigned to the IP phone, if
you have entered E911 Location IDs and if the IP phone has an E911 location ID assigned to it.
2. If no E911 Location ID entry has been assigned to the IP phone, or if the assigned LID does not match any
entry in the Location ID table then the system will transmit the E911 information configured for the
extension in MaxAdministrator under PBX > Extension Configuration (see the chapter Extension
Configuration in the Administration Manual for details)
3. If no E911 data has been configured for the extension under PBX > Extension Configuration, then the
system will transmit the extension’s DID number.
4. If there is no DID number assigned to the extension, then the system will transmit the trunk’s Transmitted
Caller ID (which is set in the Trunk Configuration window).
5. If the Area Code and Phone Number have not been configured for the trunk, the System Main Number in
the System Configuration window will be sent.
E911 Location ID Configuration Process
Following is an overview of how to configure E911 data for IP phones:
1. Administrators create the various E911 Location IDs, one for each site, floor, or building. See
