+===================
+Call from anywhere
+===================
+
+Start a call with any user directly from the avatar menu.
+No need to navigate to a conversation first; call while working on files, tasks, or other activities!
+
+Accessing the call menu
+-----------------------
+
+1. Click on a user's avatar from any app in your Nextcloud workspace to open a menu
+2. Select ``Call {user}``
+3. A direct call is initiated immediately in a floating window

+
+Best Practices
+~~~~~~~~~~~~~~
+
+- **Check availability**: Check user status to see whether people are available before calling
+- **Respect preferences**: Some may prefer messages over calls. Could this have been an e-mail?
+- **Switch to groups**: Create a dedicated conversation for multi-user discussions

+Organizing conversations
+========================
+
+Nextcloud Talk offers features to organize and manage your conversations efficiently.
+
+Tags
+----
+
+Create custom tags to categorize your conversations and keep them organized.
+Tags help you group conversations by project, team, topic, or any other criteria that makes sense for your workflow.
+
+.. image:: images/conversations-tag-overview.png
+    :alt: Talk conversations tag appearance
+    :width: 400px
+
+1. Select a conversation and open actions menu
+2. Select ``Tags`` and choose an existing tag or create a new one
+3. The conversation will now be tagged and grouped accordingly
+
+You can later manage existing tags by renaming, reordering or deleting them.

+    :width: 400px
+
+Sorting and grouping
+--------------------
+
+You can additionally customize how conversations appear in the list.
+They can be sorted:
+
+- **By last activity**: Show most recently active conversations first (default)
+- **Alphabetically**: Sort conversations alphabetically by name
+
+Similar types can also be grouped together:
+
+- **Do not group by type**: Keep a flat list of all conversations
+- **Show private ones first**: Show private conversations before groups/public
+- **Show group ones first**: Show groups/public conversations before private

+Conversation presets
+======================
+
+Conversation presets allow administrators to define templates for new conversations, with pre-configured settings such as permissions, lobby rules, and conversation type.
+
+Available presets
+-----------------
+
+Depending on your instance configuration, you may see presets when creating a new conversation.
+Each preset applies a specific set of defaults suited to a particular use case.

+
+Voice room
+----------
+
+A permanent call room ("Voice room") is a conversation preset optimized for non-obligatory, always-available meetings.
+Any person entering the conversation will be joining the call there, making it easier to start communicating.
+Messages in voice room conversation are set to expire after certain time, to keep it lightweight and spontaneous.
+
+Webinar
+-------
+
+Moderators can configure a preset to force the lobby, ensuring participants wait for a moderator before joining.
+When a conversation uses a forced lobby preset:
+
+- Participants see a waiting room upon joining
+- A moderator must allow them to the conversation or lift the lobby
+- Useful for webinars, interviews, or controlled meetings
+
+Presentation
+------------
+
+Presentation preset is useful for internal meetings, where it is expected to have more listeners than speakers.
+Participant permissions are optimized to ensure the best performance and moderation experience, allowing presenters to speak uninterrupted.
