Form B: Mailboxes Description

The mail system comes with the following factory-setmailboxes.

General Mailbox for Automated Attendant 1	Mailbox No. 9991
General Mailbox for Automated Attendant 2	Mailbox No. 9992
General Mailbox for Automated Attendant 3	Mailbox No. 9993
System Administrator’s Mailbox	Mailbox No. 9997

All other mailboxes must be created. For security reasons, the mail system will not transfer a call to any communications system extension, Calling Group, or Hunt Group that does not have a mailbox. Therefore, you must create a mailbox for every extension, Calling Group, and Hunt Group that callers need to reach from the mail system, with two exceptions:

■The extension designated as the Call Answer Service Operator does not have to have a mailbox.

■Fax Extensions should not have mailboxes.

Security Alert:

To prevent possible toll fraud abuse, mailboxes should exist only when they are needed. That means that they should be created only as they are needed, and that they should be deleted when they are no longer needed.

Class of Service

Each mailbox is assigned a class of service (COS) that defines the characteristics of that mailbox as shown in the COS Table on page A-8. Following is a description of each column of the COS Table.

■Mailbox Storage is the total time available for stored messages in an individual mailbox.

The factory-set total storage time available for all mailboxes is six hours for a two-port system, 11 hours for a four-port system, and 16 hours for a six-port system. The storage time for all mailboxes that are created can exceed the total storage time available for the system. However, when the total storage time has been used, the mail system will not take any more messages, even though an individual mailbox may not be full. Call Answer Service mailbox owners (called subscribers) must delete messages to free space for new messages.

■Message Length is the maximum length of a message that can be recorded by a caller.

■Greeting Length is the maximum length of the personal greeting for a Call Answer Service or Transfer-Only mailbox and for a Bulletin Board message. In bilingual mode, the greeting length applies to each language. For example, a subscriber can record a 2-minute personal greeting in the primary language and a 2-minute personal greeting in the secondary language.

■Transfer Permitted defines how the mail system processes a call when a caller identifies this mailbox as a transfer destination:

—If transfer is permitted, the mail system tries to transfer the call to the extension, Calling Group, or Hunt Group associated with the mailbox as identified by the caller.

—If transfer is not permitted, the system does not try to transfer the call to the extension, Calling Group, or Hunt Group identified by the caller. Instead, the system transfers the call directly to the mailbox. Use this for mailboxes that do not have extensions, Calling Groups, or Hunt Groups associated with them.
