56.00 Account Code Verified
Description
Account Code Verified is used to prevent the extension users from making
unauthorized outside calls by checking the validity of the entered account code.
In default mode, the validity of the entered account code is not checked by the
system.
When Account Code Verified is utilized, account code entered before making an
outside call is checked against the list of system account codes.
If the entered account code matches one of the codes on the list, the outside call is
completed after passing through the toll restriction procedure.
If not found on this list, reorder tone is returned to the extension user and the
outside call is restricted.
From Software version 15.XX or higher, toll restriction procedure for Account
Code verified calls has changed.
See "Additional Information" on page 10-C-92 for further information.
System Account Codes for this feature can be registered in the Speed Dialing
Screen by dividing it into two areas using SPB command.
This feature is applied to the extension user whose Class of Service No. is
assigned to "Y" by entering ACV command at dumb programming mode.
System Account Codes are not assignable, if Tenant Service is employed.
To utilize this feature, the following programming should be done beforehand.
(1) Programming the System Account Codes-Speed Dialing Boundary (SPB)
To register the System Account Codes, first divide the System Dialing Screen
into two areas by entering SPB command.
When divided, the first area is used to register Speed Dialing Codes and the
second area is used to register System Account Codes.
SPB command is available only when tenant service is not employed.
<Example>

Speed Dialing Screen, enter as follows.
; PRG>SPB AT<CR>
; Speed Dial Boundary ------------- 200
