doorbell metaphor: button controls and tracks video conference call states

Ordinal	Color	State	Visibility	Enabled
5	Black	DOWN/OFFHOOK/REJECT   Agents start in this state and may enter it as a result of network events. Double clicking in response to incoming call rejects the call and the subscribers ringer is briefly in this state to acknowledge the drop. Double clicking during a call disconnects it and while that is being confirmed, the control is this color before returning to ATTENTION.	Both	No
-1	White	OFFLINE   No subscriber context or caller device rejected.	Caller	No
0	Cyan	ATTENTION   Ordinary ringer state, like a backlit doorbell, ready to join or originate a call. Blinking indicates ring (slow) or busy (rapid). Single click rings (caller) or answers (subscriber) moving to IN CALL. Subscriber double clicking when there's no call toggles offhook. Long click moves to LOOKUP/PAGE.	Both	Yes
1	Blue	LOOKUP/PAGE   If there is no selected subscriber to connect to, clicking prompts for the subscriber or group lookup text, which is then looked up. If the lookup finds an active call, the join processing for this Agent and call begin, otherwise the control returns to this state. If there is a selected subscriber, they are sent the call id to join. Double clicking moves to ATTENTION.	Both	Yes
2	Yellow	BUFF/WAIT   Indicates incoming events for the agent. The control is inhibited if it is solidly this color .	Both	If blinking
3	Green	IN CALL   Call active, blinks when additional callers join the call.	Both	Yes
4	Red	AFK/ASIDE/BUSY   A subscriber controlled state which blocks ATTENTION requests. Click toggles, blinks while block active.	Subscriber	Yes
