911 Calls with Networked IP Phones
When using IP telephones at a remote site (Site B) which are registered to the main system (Site A),
you can use the ARS Class of Service Matching feature added in software 2.63 to route 911 calls to
the local authorities at the remote location. Without this programming, since the phones are regis-
tered to the main site, when 911 calls are placed by IP phones, the local authorities at the main site
(Site A) would be called.
Programming at the Main System
➻10-27-01 : IP System ID
For each network node, assign an ID and corresponding IP address of the networked IP system.
➻26-01-01 : Automatic Route Selection Service - ARS Service
Enter “1” to enable ARS.
➻26-01-06 : Automatic Route Selection Service - COS Match Access
Enter “1” to enable COS Matching.
➻26-04-01 : ARS Class of Service
Assign the IP extension’s ARS Class of Service (0-16).
➻26-02-01 : Dial Analysis Table for ARS /LCR - Dial
Define the Dial Analysis Table. Enter “911” in a table.
➻26-02-02 : Dial Analysis Table for ARS /LCR - Service Type
For the 911 Dial Analysis Table, enter the “1” to route the call to a trunk group.
Note: With PCPro/WebPro, the option is displayed as “Incoming Ring Group”.
➻26-02-03 : Dial Analysis Table for ARS /LCR - Additional Data
Enter the network ID number which corresponds to the entry in Program 10-27 preceded by
“1”. (For example: ID 01 is entered as “101”, 02 is entered as “102”, etc.)
➻26-02-04 : Dial Analysis Table for ARS /LCR - ARS Class of Service
Assign the ARS COS to the 911 Dial Analysis Table.
Each remote site needs to have a different ARS Class of Service. If, for example, there were 50 IP
sets on one remote site, each would use the same ARS Class of Service.
It is important to remember that there must be a trunk available to make a call across the network
from the main system. Then, by default, the system will access the first available trunk in trunk
group 1 at the remote side to place the 911 call.
