Changing PINs regularly.• When a CO line call is made using Verification Code Entry:– the Class of Service of the specified extension is applied (® 3.1.21 COS (Class of Service))– the Itemized Billing code of the specified extension is applied (® 1.1.3 ARS (Automatic RouteSelection))– + verification code is recorded on SMDR as the call originator, instead of the extension number ofthe actual extension used (® 16.1.3 SMDR (Station Message Detail Recording)).• Verification Code Entry through DISAThis feature is also available through DISA.
