CAUTION
There is a risk that fraudulent telephone calls will be made if a third party discovers your
password (verification code PIN).
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 your PIN secret.
b.
Selecting a complex, random PIN that cannot be easily guessed.
c.
Changing your PIN regularly.
