Check real-time features, calls and meetings

Messages and presence

• Check thread membership and read permission.
• Reload the view once when messages, reactions or presence are missing.
• Compare VPN, proxy and WebSocket filtering when ordinary requests work but real-time changes do not.
• For external inbox messages, also check provider account, conversation state and record link.

Audio, video and telephony

1. Check browser and operating-system permission for microphone and camera.
2. Select the correct input and output device and check mute state.
3. Close other programs that use the device exclusively.
4. For telephony, check the verified number, default number and tenant configuration.
5. For meetings, compare invitation, lobby, participant state and guest-link validity.

Diagnostic details

Record the call or meeting type, time, browser, participating internal accounts and, if visible, session or request ID. Conversation contents, recordings and complete guest links belong only in explicitly agreed secure channels.

Reconnecting may request media permission again. Never repeat a recording or sending operation until the previous state is clear.
