1.2 Making Calls
• 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:

• If you dial 4 digits or more when dialling 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.
• If the DISA Automated Attendant (AA) service is used, you can access the desired party
simply by pressing a preprogrammed single-digit number (DISA AA number) while or after
hearing a DISA OGM or after a short beep. AA menus can be up to 3 levels deep.
• If you enter an invalid security code 3 times consecutively, the call will be disconnected
automatically. If you enter a DISA security code a second and third time, dialling " " is not
necessary.
