1.2 Flexible Buttons
The flexible buttons access lines and features based on the IP Phone configuration. Flexible
buttons assigned for line access, which are called line buttons, represent a telephone line or a
SIP user. A line may be private; calls to a private line signal at all appearances of the line but
an active or held call is only visible and accessible by the original end-point.
A shared line, also known as a MADN (Multiple Appearance Directory Number) line, may
appear at multiple phones and all calls are visible and accessible by all end-points with the line.
A DSS/BLF (Direct Station Selection/Busy Lamp Field) line provides enhanced operation
incorporating two functions associated with the needs of an answering position:
o DSS – calls the associated extension.
o BLF (Presence) – the button LEDs or LCD for the line displays the line status (idle,
busy).
When Presence is enabled, DSS Lines subscribed as a Presence group line. In this case, the
DSS/BLF button indicates busy (LED On) and idle (LED Off) for the line, as well as calling to the
associated extension.
