Multi-line terminal

A Multiline Terminal user can use a customer-provided headset in place of the handset. Like using
Handsfree, using the headset frees up the user’s hands for other work. However, Headset Operation
provides privacy not available from Handsfree.
As the headset plugs into a separate jack on the bottom of the telephone, the handset can still be
connected to the telephone. This gives you the option to use the handset, headset or the
speakerphone for calls.
