•	Rotary single line telephone (SLT) users cannot use this feature.

1.2.7 Accessing Another Party Directly from Outside (Direct Inward System Access [DISA])

When an outside caller dials a specified telephone number of the PBX, a prerecorded Direct Inward System Access (DISA) outgoing message (OGM) can greet the caller and give information about how to access an extension. The operator does not need to be involved. If there is no recorded message, the caller will hear a short beep instead of the DISA OGM.
The caller may also be able to access system features or call an outside party by using the caller's password (DISA security code), depending on the security mode. Ask your manager about the mode assigned to your PBX.

To call an outside party

•

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 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.
