PLAYING BACK MESSAGES
Description
If at least one message has been left, the user can play back the messages in his mailbox, using a
range of possible functions (delete, next, replay, send a copy, call back, etc).
Messages are played back in two series: the new messages first, then the old ones. Each series is in
chronological order.
Caller identification
While the messages are played back, the terminal display indicates:
- the name of the caller - if known, and if the user has the corresponding feature rights
- otherwise, the caller's number
- **** if the caller has activated the CLIR or "Secrecy" service
- "Unknown" if the caller number is not recognized by the system.
The identity of the caller is never announced.
Date and time
The date and time of arrival are displayed on the terminal and announced before the message is
played back.
Call-back
When the caller's identity is known to the system (CLIP: Calling Line Identification Presentation), this
service enables the user to immediately call back correspondents (whether internal or external) who
leave a message. The call-back number can contain a maximum of 20 digits. Call-back can be re-
quested while still listening to the message, or afterwards.
There are several possibilities:
- Internal call: internal callers can be called back without restriction.
• If the VMU was activated in Connected mode, the transfer is of the semi-supervised type:
• If the user doesn't answer: the call is transferred and dynamic routing is activated.
• If the user is busy (degree 1 or 2): the call is not transferred and the user is returned to the mes-
sage playback menu.
- If the VMU was activated in Application mode, the transfer is of the blind type: the application
transfers the call regardless of caller status and immediately goes on-hook; if the call-back fails,
the user has to hang up and call back the VMU (or press Redial).
- External call: The call-back of external callers is governed by barring mechanisms. The VMU
transfers the call when the connection is established (correspondent off-hook) or simulated.
