You can store up to 32 DISA/TIE User Codes with a COS level for each. Each code should be unique.
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.
Default: All locations: Not Stored
All COS: 96
