If you have an active call, with no calls waiting, and you then put the active call on hold, the red (end call) button 

is removed from display. this means that you must re-activate the held call before you can end it (press the green 

arrow). see the figure below:

  Note: call waiting is not the same as call collision, which is what happens when you are talking on one 

phone (e.g., your desk phone) and a new call comes in on another phone (e.g., your mobile phone). see 

Section 8.6: Managing Call Collision for details about how this is handled.

  Note: if call waiting is active when a call collision occurs, then the touchscreen will indicate the collision 

and enable you either to ignore the incoming call or to answer it, thus dropping all of the active and held 

calls being managed by call waiting. the headset, however, does not provide a tone to inform you of a call 

collision if you have held calls; it essentially ignores the colliding call until there are no more calls on hold.
