WARNING
There is a risk that fraudulent telephone calls will be made using the Outside-to-
Outside Call feature of DISA.
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)
Enabling DISA security (Trunk Security or All Security).
b)
Keeping your passwords (verification code PIN/extension PIN) secret.
c)
Selecting complex, random PINs that cannot be easily guessed.
d)
Changing PINs regularly.
