• WARNING
There is a risk that fraudulent telephone calls will be made using the 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 (CO Line Security or All Security).
b) Keeping your passwords (verification code PIN/extension PIN) secret.
c) Selecting complex, random PINs that cannot be easily guessed.
d) Changing PINs regularly.
• Time limit
Both parties will hear an alarm tone fifteen seconds before the specified time limit. To extend,
press any dial button except .
• If Built-in Automated Attendant service is set, you can access the desired extension
simply by pressing a single digit (0–9) from the options given the prerecorded message.
• When using a proprietary telephone, you can set or cancel DND by pressing the FWD/DND
button (fixed button) instead of " 710".
