Single-line telephone/multi-line telephone

Your OpenStage 40/40 G is a "multi-line telephone". This means that multi-
ple lines can be configured, which is not the case with single-line phones.
Each line is assigned an individual phone number which you can use to
make and receive calls.
The programmable sensor keys function as line keys on multi-line phones
page 22.
The "Overview" tab on the telephony interface provides information about
the lines configured on your phone and the current status of each line
page 30.
A number of specific features must be considered when using a multi-line
phone to make and receive calls page 109.
