Feature Reference
When you call a co-worker with a display telephone and get no answer or a
busy signal, press a programmed Leave Message button or press the Feature
button and dial
display while listening to ringback or a busy tone. A message is sent to the
display telephone user. The message includes the caller's name (if labels are
programmed) or extension, and the time and date of the call.
If the caller leaves another message for the same person before that person
responds to a previous message, the previous message is overwritten. A person
with a display telephone who has received a message sees only the caller's
name (if labels are programmed) or extension and date and time for the new
message.
To use the Leave Message feature without calling a user, the multiline telephone
user presses the Feature button (without lifting the handset) and then dials
and the person's extension number. QCC operators cannot use Leave Message
without calling the user.
NOTE:
If the Message LED of the person receiving the message is already on, using
the Leave Message feature does not turn the LED off even if an operator uses
Leave Message to send a message to a display telephone user.
When a person with any telephone tries to use the Leave Message feature to
send a message to a person with a single-line telephone or a multiline
telephone without a display, the caller hears a single beep indicating that a
message must be left with the operator. If the caller has a display telephone, the

When a user tries to use the Leave Message feature and the co-worker's
message box is full, the co-worker's telephone continues to ring and the caller's
telephone beeps once. If the caller has a display telephone,
is displayed, and the caller must leave a message with the operator or voice
mail (if available).
Cancel a sent message by pressing the Feature button and dialing
extension where the message was sent. QCC operators cannot cancel
messages they sent.
Receiving Messages
When the Message LED on a telephone is on or when a single-line telephone
user hears a stutter dial tone when lifting the handset, there is a message
waiting for that person or for the calling group (if the extension is programmed
as a message-waiting receiver for a calling group). The message can be from
