Directory Listing and/or Recorded Name
Users and callers can use a Directory to reach a user whose extension they do not know. Users can also use the Directory to address messages to other users. A Directory listing can be up to ten letters in length. The mailbox user's name can also be recorded. Both the System Programmer/Manager and the mailbox user have record capability, but only the System Programmer/Manager can program a directory listing for an extension.
In Release 1 and 1.1, a Directory Listing can be up to four letters in length.
