Lines

The number of available lines differs between licence levels. Incoming calls are routed to line 6. They are indicated by a blinking red LED. Active lines are signalled by a continously illuminated green LED. By clicking at an active line during a phone conversation, the line is set to the "on hold" state. "On Hold" is indicated by a blinking green LED. If your Public Branch Exchange (PBX) supports "music on hold", the party that has been set on hold will heart that music. In order to unhold a line, simply click at the line. You'll then be able to continue your conversation with the remote party that was on hold.

11

Conference

If there are calls on more than one line (on hold or active), a simple click at the "conference" button  is sufficient to create a conference. All parties that have previously been on hold or active are instantaneosly added to the conference. If you click at an unused line (a line that is idle) while being in a conference, e.g. to reply to an incoming call or to make a new call, all participants of the conference are set "on hold". This is indicated by blinking green LEDs on the line buttons. By clicking at the "conference" button, the conference between all active parties and the parties that had been "on hold" is reestablished.
