Emergency Routing
J
When an extension user dials 911, the system can automatically find a trunk for the call. The
system can choose a route to which the user normally does not have access. If all normal routes
are busy, the system can even disconnect an active call and place the emergency call. E911
Compatibility uses the flexibility of the Automatic Route Selection Call Route Options to route 911
emergency calls (even in systems in which ARS is not enabled).
E911 Outgoing Dialing
N
The E911 calls follow the trunk group route programming. It is possible to use the flexibility of the
Automatic Route Selection Call Route Options for additional routing options.
Forced Disconnect Follows Timer to Disconnect Call
N
When all lines in the programmed route are busy and the system must drop a call in order to place a
911 call, the system will wait the amount of time set in Program 81-01 before disconnecting the call.
Compatibility with Customer Provided E911 Equipment
J
The system can automatically send a 911 call to customer-provided E911 equipment (such as the
Proctor 911 ANI-LINK System II). The E911 equipment will dial emergency service and provide the
caller's extension number to the emergency personnel. When using this type of equipment, the
system must be programmed to send E911 calls to the trunk connected to the E911 box. This is
done by assigning the trunk to the E911 trunk group and using ARS to route all 911 calls to that
port. The Dial Treatment must then be set to send the extension number and '911' to that port. This
is usually accomplished using XRE in the Dial Treatment, but check the requirements of your E911
box.
Calling Party Identification
J
With ISDN installed, the system can provide the calling party's telephone number and extension
number. No additional customer-provided 911 equipment is required.
Uninstalled Trunks in Trunk Group Prevent Call from Dialing Out
By system default, all trunks in
the system will try to access the trunks defined in the group. If the trunks do not exist, the call will not dial
out. In order for E911 to function correctly, remove any uninstalled trunks from the trunk group.
If Program 21-01-12 : System Options for Outgoing Calls, Dial 911 Routing Without Trunk Access is set
to "0" (trunk access code required), when using the Dial Number Preview feature and dialing 9+911, if all
trunks are busy, the user will hear a busy signal and the call will not dial out.
If option 21-01-12 is set to "1" (trunk access code not required) and using Dial Number Preview, 911 is
dialed, the system will disconnect a trunk and dial the call.
Dial Number Preview is when a telephone number is first dialed (previewing the number in the display)
then pressing the SPEAKER or line key to place the call.
