911 Call Routing
911 Call Routing : Using ARS Class of Service Matching to Call
Local Authorities
When using IP telephones at a remote site (System B) which are registered to the main system
(System 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 registered to the main site, when 911 calls are placed by IP phones, the local authorities at the
main site (System A) would be called.
This option requires Aspire software 2.63 and higher and the following programs are set in the
main system (System A).
Related Programs
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 Þrst available trunk in trunk
group 1 at the remote side to place the 911 call.
