Usage
Type as-on-local to achieve the following results:
If the administrator chooses to leave the Emergency Location
●
Extension fields (that correspond to this station's IP address) on
the IP Address Mapping screen blank, the value as-on-local
sends the extension entered in the Emergency Location
Extension field in the Station screen to the Public Safety
Answering Point (PSAP).
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 Station 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 Station 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).
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.
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.
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.
