AT&T Merlin Legend MLX-20L Operation Manual page 59

If you dial incorrectly or reach an extension that is busy or
unanswered, you can
• press Cancel to return to the original caller
• try the call again
• take a message from the caller and use Send/Remove
Message to turn on the co-worker's Message light (alerting
them that they have a message from you). If the extension
you're calling is busy or unanswered, you can use Leave
Message when you hear ringing or a busy signal.
• continue trying to connect the call with
Barge-In for an emergency or if you have been instructed
to interrupt
Camp-On to have a directed call wait a preset length of
time for the extension to become available. (If the call is
unanswered, it rings back at your console.) Release also
allows a call to ring on an unanswered or busy extension
for a preset length of time. A camped-on call usually waits
longer than a released call before it returns to an operator.
Paging to announce the call over a loudspeaker system or
over co-workers' speakerphones
Park to put a call on hold and page a co-worker to pick up
the call from another phone
