• 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.
• If you dial 4 digits or more when dialing an extension number, the call will be disconnected.
When you dial an invalid extension number of 3 digits or less, the call is redirected to the
preprogrammed intercept destinations or disconnected, according to system
programming.
• CO-to-CO Line Call Duration
The length of outside-to-outside (CO-to-CO) line calls may be limited through system
programming.
Both the outside caller and the outside destination will hear a warning tone 15 seconds
before a specified time limit. When the timer expires, the call is disconnected.
