Ft defines a call handling protocol similar to the one that has evolved with voice telephony since the late 19th Century. It is based on a canonical flow of these states with manifold exceptions:
- DOWN/OFFHOOK/REJECT
All subscribers are initially are in this state and may move to it by personal or network events.
- AFK/BUSY
A subscriber controlled state which blocks calls until the subscriber sets READY.
- ACCEPT/ANSWER/READY
A subscriber moves to this state after connecting assuming no event, such as their or the network having set a different state.
- BUFF/WAIT
A network controlled state which indicates incoming events for the subscriber. It is normal for some such events not to result in actual incoming as for example when the remote subscriber cancels a message before sending it.
- CALL/LOOKUP/PAGE
A state in which the subscriber can or has initiated a call, or can lookup a remote subscriber or group.
Visual cues, such as blinking, fade-in/out indicated attention/opportunity or operation in progress.
The overall Ft GUI operates with elements such as the taskbar, main screen, and conferees array with elements in modal focus to constrain which subscriber pairs are involved.
A distinguished subscriber in a conference call at any one time is the moderator, with overall control.
