Audiotext (Tree Mailboxes)
You can protect audiotext applications by requiring callers to enter an access code (feature bit
137) before hearing the information. Because you can design audiotext applications as a series of
mailboxes, each with individual information, you can set a unique access code for each piece of
information to ensure corporate security.
You can configure audiotext applications to hang up after playing the greeting (feature bit 062), or
transfer to the mailbox attendant (bit 063) or mailbox extension (bit 064). You can also deny login
from within the tree (bit 152).
Protection From Mailbox Owner Abuse
The revenue of a service bureau is dependent on being able to bill mailbox owners for use of the
server. Likewise, the corporate telecommunications manager must control use and potential
abuse of corporate resources to provide the best service while controlling costs and maintaining
security. The server allows you to place controls and limits in the server to ensure that mailbox
owners use the server appropriately.
Line Groups
Service bureaus can provide mailbox owners with certain line groups for receiving messages,
while having them pick up their messages on other line groups, either to control costs or to
control call flow. To enforce this type of usage, you can use feature bits 101-109 to deny login on
specific line groups; callers can leave messages, but are not able to log into a mailbox. In this
way, you can also restrict access to certain information to internal ports only, or to “800” number
ports where the server owner must pay for connect time.
Mailbox Usage
Depending on the number of phone lines or the storage hours available on your server, or on the
levels of service that mailbox owners pay for, you can set LCOS parameters to control certain
aspects of mailbox usage, such as connect time, number of messages stored, or storage
duration.
If the number of phone lines to your server is limited, you can limit call duration by setting the
Maximum login time parameter in each LCOS to a few minutes. On the other hand, if disk storage
is a limiting factor, you can lower both the Caller message length and User message length, and
set the Message count limit to a number that is equitable to all users assigned to each LCOS.
The amount of storage used on your server is the result of the number of messages stored and
the length of storage time. You can control the storage times for played and unplayed messages
by setting the two LCOS parameters: Played message retention and Unplayed message
retention.
Besides setting limits on server usage, you must ensure that your mailbox listings are current—
remove mailboxes that are no longer being used. Once you have removed a mailbox, the server
automatically removes it from the Dial-by-Name database and from all distribution lists.
Messaging
Messaging between mailbox owners is the primary purpose of many voice mail systems, but you
