Subscriber Passwords
Make sure that subscribers understand the importance of password security to their
mailboxes and implement the following guidelines:
Subscribers should change their passwords the first time they log into the
system and periodically thereafter. Consider sending a broadcast message
on the first of each month to remind them.
Subscribers can have passwords of up to nine digits to access the AUDIX
Voice Power and FAX Attendant systems. There is no minimum password
length; however, you should encourage subscribers to make their passwords
at least five digits.
Subscriber passwords are specified in their profiles on the Subscriber
Administration screen. A pound sign (#) in the
Password field denies access
to anyone trying to log into the mailbox. The system responds with login
incorrect regardless of what the caller enters. Use this feature whenever it
becomes necessary to restrict mailbox access. Once a subscriber profile is
saved, the password value will not be displayed on the screen. This is for
security purposes. If subscribers forget their passwords, the System Manager
must enter new passwords in their profiles and resave them. The old
passwords are unrecoverable.
Administrative Passwords
Administrative passwords are phone-based and computer-based passwords for the
System Managers and Service Administrators. The following are guidelines for
administrative passwords:

Make sure that the passwords set during installation are changed.
Establish and enforce procedures among administrators for changing
passwords. These procedures should include how often passwords are
changed and how notification of new passwords is made.
Because subscribers are required to choose passwords, inevitably some will
forget their passwords. To prevent unauthorized access to a subscriber’s
mailbox, establish a procedure for reissuing passwords in these situations.
Computer-based passwords must be at least six characters long.
You must include both numbers and letters in computer-based passwords.
Passwords are case-sensitive (that is, the system distinguishes between
uppercase and lowercase letters in passwords). Consider using special
characters such as dollar signs, commas, and percent signs.
