Camera, microphone, and speaker state

Choose audio or video without losing the person and message context.
Synchronize the call invitation so web and mobile participants see the same state.
Publish local tracks, subscribe to remote tracks, and expose clear controls.
Propagate decline, leave, and hang-up events so stale call surfaces disappear.
Each capability has a clear purpose and a direct place in the collaboration lifecycle.

The value appears in the handoff between a live room and the work that continues afterward.
Both participants see the same ringing, connected, and ended lifecycle.
Visible controls reflect the tracks that are actually being sent and played.
A departed participant no longer leaves a black or stale video tile behind.
The product surface keeps access, ownership, and durable context visible so teams can make deliberate choices.
These capabilities share the room, participant, and follow-up context around this workflow.
Rooms, messages, tasks, notes, calendars, and live tools share one workspace instead of becoming separate islands.
Apply deliberate admission, participant visibility, and room-level controls to collaboration that should not be public by default.
See availability, live-room presence, and current collaboration signals without interrupting the team to ask.
