2.2.7 To Access Another Party Directly from Outside (Direct
Inward System Access [DISA])
Warning for the Direct Inward System Access Users
When you enable the CO-to-CO Line Call feature of
Direct Inward System Access (DISA) function
,
if a third party discovers the password (a DISA User Code) of the system, you have a risk that they
will make illegal phone calls using your telephone line, and the cost may be charged to your account.
In order to avoid this problem, we strongly recommend the following points:
1: Carefully maintain the secrecy of the password.
2: Specify a complicated password as long and random as you can make it.
3: Change the password frequently.
To call an extension
External callers can call extensions in the
KX-TD500 system, or other external party via
KX-TD500 system. An outgoing message greets
the caller and gives information about how to
access an extension. You do not need the
Operator's assistance.
You may not be able to access the features without
entering a DISA user code depending on the
security mode. Ask your System Manager for the
mode assigned to your system.
