AltiGen MAXCS 7.0 Update 1 ACM Administration - Manual (Page 309)

E911 Hierarchy
MaxCS 7.5 Administration Manual 293
If an IP phone does not have the correct firmware version, then you cannot configure an E911 Location ID for
the phone until you upgrade its firmware.
New AltiGen IP phones are shipped with the default E911 Location ID entry of 0.
The following phones are not supported:
• AltiGen IP 600
• Analog phones connected to the MaxCS server
• Other 3rd party SIP phones
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
on page 175 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 a Location ID schema and plan various E911 Location IDs, one for each site, floor,
or building.
2. Administrators configure password protection, so that changing the E911 information for a phone requires
a user to enter a password (optional). See Requiring a Password to Change E911 Location ID on page
295 for details.
3. Administrators view (and update) the E911 assignments for IP phones. Administrators can either push the
updated information to the phones or have users enter the appropriate information on the phone itself. See
pages 7 and 8.
Creating the E911 Location ID Table
To configure location-based E911 information,
1.
Select PBX > Location Based E911 Configuration.
The panel shows the current E911 entries. To sort the table, click a column heading.
