Allows an extension user to override call barring temporarily to make a toll call from a
toll-restricted extension. The user can carry out this feature by entering one of the account
codes programmed in [310] “Account Codes”before dialling the telephone number. The
user can make a toll call with the COS number 2.
•The account code “Verify-toll (call barring)”mode at an extension permits users to
override their call barrings.
•This feature can be used on extensions assigned to call barring COS numbers 3 through
5. The COS numbers 1 and 2 will not be changed.
•If the user does not enter an account code or enters an invalid one,a regular call barring
check is done.
• When a user makes a call using this feature, it will appear on the SMDR printout with
either the entered 4-digit account code or the 2-digit index of the entered account code.
This selection is set in program [805].

feature.
