2.7.6 Verification Code Entry
Description
An extension user can enter a verification code when calling from his own or any other extension, to change
the TRS/Barring level (® 2.7.1 Toll Restriction (TRS)/Call Barring (Barring)) or to identify the call for accounting
and billing purposes. A verification code personal identification number (PIN) is required to use this feature.
Conditions
CAUTION
There is a risk that fraudulent telephone calls will be made if a third party discovers a personal identification
number (PIN) (verification code PIN or extension PIN) of the PBX.
The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a. Keeping PINs secret.
b. Selecting complex, random PINs that cannot be easily guessed.
c. Changing PINs regularly.
• When a trunk call is made using Verification Code Entry:
– the Class of Service of the specified extension is applied (® 5.1.1 Class of Service (COS))
– the budget of the specified extension is applied (® 2.7.2 Budget Management)
– the Itemised Billing code of the specified extension is applied (® 2.8.1 Automatic Route Selection
(ARS))
– + verification code is recorded on SMDR as the call originator, instead of the extension number of
the actual extension used (® 2.22.1.1 Station Message Detail Recording (SMDR)).
• Verification Code Entry through DISA
This feature is also available through DISA. (® 2.16.1 Direct Inward System Access (DISA))
• Verification Code PIN
A verification code PIN must be assigned for each verification code through system programming or
through manager programming.
• Verification Code PIN Lock
If the wrong PIN is entered three times, the line will be disconnected. If the wrong PIN is entered a
preprogrammed number of times successively, the PIN for the verification code will be locked. Only an
extension assigned as the manager can unlock it. In this case, the PIN will be unlocked and cleared.
• Budget Management for Verified Calls
A limit can be assigned to the total of all call charges for each verification code.
