calls made from an Avaya endpoint. Your use of this product indicates that
you have read this advisory and agree to use an alternative telephone to dial
all emergency calls from remote locations.
Valid entries Usage
extension
Enter extension to send the extension entered in the
Emergency Location Extension field, to the Public Safety
Answering Point (PSAP).
block
Enter block to prevent the completion of emergency calls.
Use this entry for users who move around but always have a
circuit-switched phone nearby, and for users who are farther
away from the switch than an adjacent area code served by
the same 911 Tandem office.
When users attempt to dial an emergency call from an IP
Telephone and the call is blocked, they can dial 911 from a
nearby circuit-switched phone instead.
cesid
Enter cesid to allow the switch to send the CESID
information supplied by the IP Softphone to the PSAP. The
end user enters the emergency information into the IP
Softphone.
Use this entry for IP Softphones with road warrior service
that are near enough to the switch that an emergency call
routed over the switch’s trunk reaches the PSAP that covers
the switch.
If the switch uses ISDN trunks for emergency calls, the digit
string is the telephone number, provided that the number is a
local direct-dial number with the local area code, at the
physical location of the IP Softphone. If the switch uses
CAMA trunks for emergency calls, the end user enters a
specific digit string for each IP Softphone location, based on
advice from the local emergency response personnel.
option
Enter option to allow the user to select the option
(extension, block, or cesid) that the user selected during
registration and the IP Softphone reported. Use this entry for
extensions that are swapped back and forth between IP
Softphones and a phone with a fixed location.
The user chooses between
block and cesid on the
softphone. A DCP or IP phone in the office automatically
selects
extension.
