Hardware Considerations
After you delete a mailbox, you can reassign that mailbox to another
subscriber’s extension using the “Creating a Mailbox” procedure. Remember
that mailbox numbers and extension numbers are the same. You also can
assign available mailboxes to extensions that do not have phones connected to
them so that guests—employees who work off-premises most of the time, such
as salespeople—can access messages while on the road. See “Guest
Mailboxes” on the next page for details.
After initial installation, you have default mailboxes for a predetermined number
of extensions. When you reassign mailboxes, you can use any mailbox in your
system’s dial plan. The dial plan is the maximum number of extensions
supported by your system. This means on a PARTNER Plus system, you can
create mailboxes for extensions 11 through 33; on a PARTNER II or PARTNER
48 system, you can create mailboxes for extensions 11 through 57. (Note that
the mailbox at extension 10 cannot be deleted.) Figure 5-4 shows the dial plan
for each system.

Keep in mind that the modules you have installed in your control unit may differ
from this figure, and will determine the number of extension jacks to which you
can connect phones.
