Concise story of the Ft 'doorbell', a redvant applet ∫ ∂ {Bitlbee, Jitsi, Synapse} ∂ SB/DS.

Doorbell metaphor: button color tracks network call states

Ordinal	Color	State	Control	Visibility
-1	White	OFFLINE   Disconnected state, no subscriber or subscriber not Ft 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	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.	Ringer	Both
2	Red	AFK/ASIDE/BUSY   A subscriber controlled state which blocks ATTENTION requests. Click toggles, blinks while block active.	Aux 1	Subscriber
3	Green	IN CALL  A agent moves to this state after connecting to a call assuming no event, such as their or the network having set a different state preventing same. Blinks when additional callers join the call.	Ringer	Both
4	Yellow	BUFF/WAIT  Indicates incoming events for the agent. The control is inhibited if it is solidly this color .	Ringer	Both
5	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

The designed default is collapsed with an expand tab/flap, draggable and when connected the ringer illumination will track the call state.
Obviates login/profile profile blurb for SPA, if client is authenticated device, all controls show. Otherwise if station and real device connect to DCMS>, subscriber dial/lookup/passphrase text box and Aux 2 buttons show and Ringer is not white.

When displayed on a subscribers profile, except to the subscriber, no subscriber lookup is needed or present.
