WARNING
There is a risk that fraudulent telephone calls will be made using the Outside-to-
Outside (CO-to-CO) Line 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 DISA security codes secret.
c)
Selecting complex, random codes that cannot be easily guessed.
d)
Changing codes regularly.
•
Security code numbers (not security codes) are logged by Station Message Detail
Recording (SMDR).
•
The number of digits required for DISA security codes can be assigned in DISA Security
Code Digits [530].
•
When this setting is changed, all assigned DISA security codes are cleared.
