8.00 Message Waiting
Description
Allows an extension user to indicate to another
extension that a message is waiting for him or her,
by turning on the MESSAGE indicator (button) on
the called extension.
The extension user who received the message
waiting indication can call back the message
sender by simply going off-hook and pressing the
red lit MESSAGE indicator (button).
When Voice mail turned on the message waiting
lamp, you can access directly to your own MAIL
BOX by the same operation as the "Operation by
Receiver".
This feature is useful when the called extension is
busy or does not answer the call.
Up to 500 message waiting indications can be set
for the whole system.
