Single-line telephone/multi-line telephone
Your OpenStage 15 is a "multi-line telephone". This means that multiple 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 keys function as line keys on multi-line phones ïƒ Page 20.
A number of specific features must be considered when using a multi-line phone to make and re-
ceive calls ïƒ Page 119.
Our service department can only help you if you experience problems or defects with the
