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 the states below which will be the color of the primary button. There are manifold exceptions which the network and subscriber cooperatively manage:
- DOWN/OFFHOOK/REJECT
All subscribers are initially are in this state and may move to it by personal selection or involuntarily due to network events.
- AFK/BUSY
A subscriber controlled state which blocks calls until the subscriber toggles to READY. Double click can be used to check for and view messages.
- 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. Blinking indicates at least one incoming message (slow) or call (rapid) is active. Toggles to BUSY. Double click answers calls, view messages.
- 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 has initiated a call, or can lookup a remote subscriber or group. Entered by menu or gesture depending on device.
Visual cues, such as blinking, frame highlighring, fade-in/out indicate 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 and which gestures the subscriber has available. For example single click on a call state prompts for a subscriber lookup, whereas double click when paired with a selected subscriber initiates a call/page.
A distinguished subscriber in a conference call at any one time is the moderator, with overall control. Initially it is the initiator, the first caller but thereafter it may be transferred to any party to the call.
