 Joining a call
 ================

+Browser and Talk Desktop client
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-If somebody else has started a call already, the button will change in a green ``Join call`` button.
+When you are part of a conversation and have permission to do so, you can start a call at any time by clicking ``Start call`` in the top bar.
+When a call is already in progress, join it by clicking the green ``Join call`` button in the chat area or the top bar.

-During a call, you can mute your microphone and disable your video with the buttons on the right side of the top bar, or using the shortcuts ``M`` to mute audio and ``V`` to disable video. You can also use the space bar to toggle mute. When you are muted, pressing space will unmute you so you can speak until you let go of the space bar. If you are unmuted, pressing space will mute you until you let go.
+.. note:: If you have not yet given permission to the browser or the Talk Desktop client to use your microphone and camera,
+    you will be prompted to do so when you click ``Start call`` or ``Join call``.
+    Choose the microphone and camera you would like to use and click ``Allow`` to grant access to your devices.
 
-You can hide your video (useful during a screen share) with the little arrow just above the video stream. Bring it back with the little arrow again.
+You will see ``Media settings``, where you can customise your call experience:
 
-You can access your settings and choose a different webcam, microphone and other settings in the ``...`` menu in the top bar.

+Controlling audio and video
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Use the microphone and camera icons at the bottom of the video preview to mute or unmute your microphone and enable or disable your camera before joining.
+
+.. note:: If one or both of your icons are greyed out, you either do not have a microphone or camera installed, or you did not give permission to the browser or Talk Desktop
+    client to use your microphone or camera. Check that you have granted permission to the browser or Talk Desktop client, and make sure your microphone and camera are not
+    in use by another application.
+
+Device settings allow you to choose which microphone and camera you want to use. This is useful if you have more than one microphone or camera available:

+
+Backgrounds
+^^^^^^^^^^^
+
+Backgrounds let you replace your video background with one of the predefined images.
+You can also upload your own image or choose one already in Nextcloud Files.
+Alternatively, choose the ``blur`` option to blur your live video background.
+

+
+Immediately join a call
+^^^^^^^^^^^^^^^^^^^^^^^
+
+If you wish to skip ``Media settings`` in the future, toggle the ``Skip device preview before joining a call`` switch in app settings.
+For future calls in this conversation, you will join directly, skipping the preview dialog.
+
+Record a call
+^^^^^^^^^^^^^
+
+If you started the call and wish to record it, check the ``Start recording immediately with the call`` checkbox.
+The call recording option might not be available to you, depending on whether your system administrators have enabled this option
+and whether you have ``Moderator`` permission for the conversation.
+If you are joining and the call is being recorded, you might be required to consent before being allowed to join.
+For more information, see :ref:`Call recording <call-recording>`.
+
+Start the call
+^^^^^^^^^^^^^^
+
+Click the ``Start call`` button at the bottom of ``Media settings`` to notify all conversation participants of the call.
+If you do not want to notify the other participants, start a silent call by opening the three-dot menu to the left of the ``Start call`` button
+and choosing ``Call without notification``.

-From the media settings dialog, you can also change the background of your video.
+.. note:: Other participants can modify notifications on a per-conversation level, including whether they want to receive call notifications.

+Your user status will be set to ``In a call`` and your user status icon will display the speech bubble emoji.
 
-All these settings are also available as direct actions in the bottom bar.
+Mobile clients
+~~~~~~~~~~~~~~
 
-.. image:: images/call-bottom-bar.png
+When you are part of a conversation and have permission to do so, you can start a call at any time by
+tapping the ``Phone`` or ``Video`` icon in the top bar.
+The ``Phone`` icon starts a voice-only call; the ``Video`` icon starts a video call.
+
+A voice call uses the device microphone and earpiece, like a regular phone call.
+A video call uses the loudspeaker in hands-free mode and enables your front-facing camera by default; you can disable it at any time.
+
+If someone else starts a call, you may receive a notification and your device may ring or vibrate,
+depending on your notification settings.
+Tap ``Phone`` or ``Video`` to join, or tap the red button to decline. Declining dismisses the call notification on that device.
+
+You can control your microphone and camera (if in a video call) with the options shown at the bottom of the screen.
+
+Your user status will be set to ``In a call`` and your user status icon will display a speech bubble.
+

+
