Mailbox Administration

The use of Intuity AUDIX system security features in combination with mailbox administration can help reduce the risk of unauthorized use of mailboxes.

Use the longest feasible password length. The Intuity AUDIX system allows passwords up to 15 digits, and you can specify the minimum number of digits required. Use a minimum of five digits, and a length at least one digit longer than the extension number length.

Lock out multiple consecutive attempts to enter a voice mailbox. The Intuity AUDIX system has a password time-out feature that allows callers three attempts in one call to correctly enter their password before they are automatically disconnected. You can also specify how many consecutive invalid attempts are allowed before a voice mailbox is locked.

Deactivate unassigned voice mailboxes. When an employee leaves the company, close or reassign the voice mailbox.

Do not create voice mailboxes before they are needed.

Avoid or closely monitor the use of “guest” mailboxes.

Basic Call Transfer

With Basic Call Transfer, when a caller enters processes the call as follows:

*,

T , the Intuity AUDIX system

1.The Intuity AUDIX system verifies that the digits entered contain the same number of digits as administered on the Intuity AUDIX system for extension length.

If call transfers are restricted to subscribers, the Intuity AUDIX system also verifies that the digits entered match the extension number for an administered subscriber.

2.If step 1 is successful, the Intuity AUDIX system performs a switch-hook flash, putting the caller on hold.

NOTE:

If step 1 is unsuccessful, the Intuity AUDIX system plays an error message and prompts the caller for another try.

3.The Intuity AUDIX system sends the digits to the switch.

4.The Intuity AUDIX system completes the transfer.

With Basic Call Transfer, a caller can dial any number provided the number of digits matches the length of a valid extension. If an unauthorized caller dials 9x11 (where “x” is 1 through 9), the call may go outside. Therefore extension numbers of the form 9x11 should not be used for mailboxes or for subscribers.
