Feature Guide 137
• It is possible to leave a Message Waiting notification while hearing a ringback tone, busy tone, or DND
tone.
• Message Waiting notifications are always left on the original extension. Message Waiting notifications
cannot be sent to a Call Forwarding (FWD) destination (→ 1.3.1.2 Call Forwarding (FWD)).
• Both the calling extension and the called extension can cancel a notification after it has been left.
• If a call is missed, the Message Waiting notification will be cleared when the called extension calls the
caller back and the call is answered.
• Message Waiting Notification via Voice Mail DPT (Digital) Integration
If a voice message is left for the called extension, the notification will be cleared after each new
message has been played. (→ 1.21.2 Voice Mail DPT (Digital) Integration)
• Message Waiting Notification via Voice Mail DTMF Integration
If a voice message is left for the called extension, the notification will be cleared either by the PBX after
the MESSAGE button (or a Message button) is pressed, or by the VPS after each new message has
been played, according to system programming. (→ 1.21.3 Voice Mail DTMF Integration)
