• 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.
