Manual Operation (Analog Multiline Telephones Only); Specialty Handsets - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Adjuncts
Headsets
Headsets allow for hands-free telephone use and consist of several
components, depending upon whether manual or one-touch operation is used.
Any AT&T headpiece works in either of these two modes of operation. For more
information about installing and using headsets, see the user or operator guide
for the telephone where the headset will be connected.
Headpieces
Six different headpieces are available as headset components. Each is light,
comfortable, and uses a transparent voice tube to eliminate any cumbersome
large microphone.

touch another button to hang up.
