Message Waiting ✓
❑
Message Waiting is available on most multiline telephones, and
is a feature that can be used by anyone in the system. Most
telephones have a light that indicates a waiting message.
You may also have a
MESSAGE
button, which you can press to
turn the light off after you receive messages. If your telephone
does not have a
MESSAGE
button, you must use a feature access
code to turn it off. (If you want to check on the feature
associated with the
MSG WAIT
button, go to the section titled
“Personal Message Waiting”.)

or the extension you dialed is invalid.
