BOMBARDIER Challenger 300 Cabin Handbook page 25

The standard MagnaStar handset has a hook switch that is activated by a
magnet in the holder. Remove the handset from the holder to establish an
off-hook condition and activate the handset. Return the handset to the holder to
establish an on-hook condition. Optional handset installations, including
custom holders and portable handsets that plug into jacks, do not provide this
hook-switch function. To place these handsets off-hook, press +. To put these
handsets back on-hook, press +.
While the handset is on-hook, the Services Menu
services menu displays those services available to the user. In addition, the
services menu will indicate the inplane number assigned to the handset, and the
Aircall phone number. When the handset is placed off-hook, the services menu
displays for approximately 5 seconds before defaulting to the Main Menu
(Figure 10). The current communication link displays at the top of the main
menu.
