doorbell metaphor: ringer controls and tracks video conference call states

Ordinal	Color	State	Control	Visibility
-1	White	OFFLINE   Disconnected state, no subscriber or subscriber device not authenticated.	Ringer	Caller
0	Ivory	ATTENTION   Ordinary ringer state, like a backlit doorbell, ready to accept or originate call. Blinking indicates ring (slow) or busy (rapid). Single click rings (caller) or answers (subscriber) moving to IN CALL.	Ringer	Both
1	Blue	LOOKUP/PAGE   Agent has initiated a call, or lookup of a remote subscriber or group. Submits the subscriber lookup text. Lookup is the action when no subscriber is selected and page is the action if one is (ringer calls selection).	Aux 2	Both
2	Yellow	BUFF/WAIT   Indicates incoming events for the agent. The control is inhibited if it is solidly this color .	Ringer	Both
3	Green	IN CALL   Call active, blinks when additional callers join the call.	Ringer	Both
4	Red	AFK/ASIDE/BUSY   A subscriber controlled state which blocks ATTENTION requests. Click toggles, blinks while block active.	Aux 1	Subscriber
5	Black	DOWN/OFFHOOK/REJECT   Agents join the network in this state and may move to it by personal selection or involuntarily due to 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. Subscriber double clicking when there's no call toggles offhook. Double clicking during a call disconnects it with brief acknowledgement in this color before returning to ATTENTION.	Ringer	Both

Obviates login/profile blurb, if device authenticated device, SPA tries to run FSA, which if it connects to DCMS>, subscriber dial/lookup/passphrase multiselect and Aux 2 button show and Ringer is not white.
On a subscribers profile, viewed by others, the subscriber is the callee so no lookup is present.
