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:
Keeping PINs secret.
Selecting complex, random PINs that cannot be easily guessed.
Changing PINs regularly.
Only one manager password can be assigned per PBX.
