Just checked the Manual this is all that it says on the interview service (Australian Model)
5.2.9 Interview Service
The subscriber can leave a series of prerecorded questions (up to 10) for the caller in an
Interview Mailbox. As the caller answers questions, answers are recorded in the mailbox. After
a caller records the answers, the interview mailbox lights a message waiting lamp. When
retrieving the messages, the subscriber only hears the answers to the questions.
There are 2 ways to access an interview mailbox:
• Assign an interview mailbox to an existing mailbox
• Assign a port as an interview mailbox
To structure an interview mailbox:
1. From the System Administration Top Menu, Type [1-1-1 Mailbox number-1].
(Program - Mailbox Setting - Enter/Edit - Mailbox number - Mailbox setting).
2. Enter the mailbox number that is to be assigned to the interview mailbox.
This should be an existing mailbox number for the person who responds to the questions.
3. At "6. Interview Mailbox Number "parameter, enter a nonexistent mailbox number. This
will be the interview mailbox for this subscriber — please make a written note of it for
future reference. It will not show up in Mailbox Listing. If, at a later time, you want to delete
the interview mailbox, press backspace at "6. Interview Mailbox Number".
4. Exit System Administration Programming.
5. Record the questions by entering the subscriber's mailbox. Call the VPS and Press [#6 ] +
the mailbox number assigned to the interview mailbox. From the Main Menu Press [6-1].
Note
When using the Custom Service setting, 1 digit can be assigned to go to the mailbox
of the Interview Service. The mailbox owner's message waiting lamp will go on for
normal Voice Mail messages and for messages left in the separate interview mailbox.
