AT&T 3 manual Considerations and Constraints

Mailbox

Considerations and Constraints

■For security reasons, the mail system will not transfer a call to any destination that does not have a mailbox. Therefore, you must create a mailbox for every extension, Hunt Group, and Calling Group that callers need to reach from the mail system.

There are two exceptions:

—The extension designated as the Call Answer Service Operator is not required to have a mailbox.

—The extensions or Hunt Groups designated as Fax Extensions should not have mailboxes.

■A total of 100 mailboxes (Automated Attendant mailboxes, Call Answer Service mailboxes, and Bulletin Board mailboxes) can be created, but to avoid call traffic problems, a maximum of 60 is recommended for a six-port system, 40 for a four-port system, and 20 for a two-port system.

■Up to 58 Transfer-Only mailboxes can be created.

■When a caller is listening to a Bulletin Board message, the mail port that the caller is using is not available for other calls. Therefore, you must take into account port usage when creating Bulletin Board mailboxes. If you want to have many Bulletin Board mailboxes, you may want to add more ports to the system. Contact your salesperson or authorized dealer.

■You can modify the Class of Service for a mailbox if the new Class of Service is for the same Mailbox Type. For example, you can change a mailbox from Class of Service 2 to 3 because both are Call Answer Service mailboxes. You cannot, for example, change a Bulletin Board mailbox (Class of Service 19) into a Call Answer Service mailbox (Class of Service 1–6 or 18). If you want a mailbox of a different type, you must delete the unwanted mailbox and create a new mailbox with the desired Class of Service.
