Valid entries Usage
as-on-local Type as-on-local to achieve the following results:
●
●
●
block Enter block to prevent the completion of emergency calls. Use this entry for
users who move around but always have a circuit-switched telephone
nearby, and for users who are farther away from the media server or 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 telephone
instead.
cesid Enter cesid to allow Communication Manager 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 media server or switch that an emergency call routed over the
it's trunk reaches the PSAP that covers the server or switch.
If the media server or 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 media server or 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 can be swapped back and forth between IP
Softphones and a telephone with a fixed location.
The user chooses between block and cesid on the softphone. A DCP or IP
telephone in the office automatically selects extension.
If the administrator populates the IP Address Mapping screen with
emergency numbers, the value as-on-local functions as follows:
If the Emergency Location Extension field in the Attendant screen
is the same as the Emergency Location Extension field in the IP
Address Mapping screen, the value as-on-local sends the extension
to the Public Safety Answering Point (PSAP).
If the Emergency Location Extension field in the Attendant screen
is different from the Emergency Location Extension field in the IP
Address Mapping screen, the value as-on-local sends the extension
in the IP Address Mapping screen to the Public Safety Answering
Point (PSAP).
