The Line Assignment tab enables you customize lines by setting the programmable button as a line appearance button to make and answer calls on a particular line.

For systems operating in PBX System mode, buttons can also be selected for ARS selector group numbers. Those can be used to make calls but not to receive calls. When pressed, an available line in the ARS selector group is seized.

Note that for systems running in Key System mode, a number of each users programmable buttons are automatically configured as line appearance button according to the system Number of Lines setting. If the system setting Number of Lines is changed, it may overwrite all or some of the current button programming.

Select the line with which the button will be associated. For systems operating in Key System mode, the ARS Selector group numbers are also listed.
