Tele Doorbell — join point for Ft aspect of domain space deployed to the communal networks
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 incoming call (slow) or conference (rapid). Double click toggles to BUSY. Single click answers moving to IN CALL.	Ringer	Caller
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. Single click moves to ATTENTION, double focuses CALL/PAGE input and moved to that state.	Ringer	Subscriber
2	Red	AFK/ASIDE/BUSY   A subscriber controlled state which blocks ATTENTION requests until an agent click toggles to ATTENTION/IN-CALL or double clicks to OFFHOOK.	Aux 1	Both
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.	Ringer	Both
4	Yellow	BUFF/WAIT  A network controlled state which indicates incoming events for the agent. It is normal for some such events not to result in actual incoming as for example when the remote agent cancels a message before sending it. The control is inhibited if it is solidly this color .	Ringer	Both
5	Blue	CALL/LOOKUP/PAGE   A state in which the agent has initiated a call, or lookup of a remote subscriber or group. Entered as a result of data entry in UI and subsequent network events determine which state results.	Aux 2	Caller

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 (or Jitsi meet passphrase) text box and Aux 2 buttons show and Ringer is not white.
