Emergency Call Feature
Page 129
• If the user dials the emergency feature code from an endpoint with a trunk or trunk
group programmed as the Emergency Extension, the Emergency Call feature routes the
call based on the endpoint’s Emergency Extension. The trunk or trunk group does not
validate the endpoint originating the emergency call against the trunk group’s Emer-
gency Day/Night Outgoing Access List. An idle trunk is seized, and the system auto-
matically dials Emergency Number 1.
• If the user dials the emergency feature code from an endpoint with ARS programmed as
the Emergency Extension:
a. The Emergency Call feature routes the call based on the endpoint’s Emergency
Extension.
b. The call is routed to Route Group 1.
c. The call tries the first facility group in Route Group 1.
d. The trunk group or node trunk group validates the endpoint originating the emer-
gency call against the group’s Emergency Day/Night Outgoing Access List.
e. If the call is denied, it tries the next member in the facility group. If each member
denies the call, the call tries the next facility group in Route Group 1’s list.
If everything is denied due to Emergency Outgoing Access, the call is routed once
again to Route Group 1. The call then tries the first facility group in Route Group
1. The trunk group or node trunk group does not validate the endpoint originating
the emergency call against the group’s Emergency Day/Night Outgoing Access
List. If no trunks are available, the call tries the next member in the facility group.
If all of the members are unavailable, the call camps-on to Route Group 1 until a
trunk is available.
• If the user accesses a trunk or trunk group and dials any Emergency Number (1–10),
the trunk or trunk group does not validate the endpoint originating the emergency call
against the trunk group’s Emergency Day/Night Outgoing Access List. An idle trunk is
seized, and the system automatically dials the emergency number.
• If the user accesses ARS and dials any Emergency Number (1–10):
a. The call is routed to Route Group 1.
b. The call tries the first facility group in Route Group 1.
c. The trunk group or node trunk group validates the endpoint originating the emer-
gency call against the group’s Emergency Day/Night Outgoing Access List.
d. If the call is denied, the call tries the next member in the facility group. If each
member denies the call, the call tries the next facility group in Route Group 1’s
list.
If everything is denied due to Emergency Outgoing Access, the call is routed once again to
Route Group 1. The call then tries the first facility group in Route Group 1. The trunk group or
node trunk group does not validate the endpoint originating the emergency call against the
group’s Emergency Day/Night Outgoing Access List. If no trunks are available, the call tries
the next member in the facility group. If all of the members are unavailable, the call camps-on
to Route Group 1 until a trunk is available.
NOTE
Inter-Tel highly recommends that only local trunks be installed and used for
emergency trunk access and that only local trunks be programmed in Route
Group 1. Programming a node in Route Group 1 may cause the system to
access a trunk on a separate node when ARS is used for emergency access. If
this occurs, Emergency Outgoing Access is no longer validated.
