1.2.8 To Access Another Party Directly from Outside (Direct Inward System Access [DISA])
CAUTION
There is a risk that fraudulent telephone calls will be made using the Outside-to-Outside 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 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.
