RoomVox

CalDAV-native room booking for Nextcloud. Rooms appear as bookable resources in any calendar app — no separate booking interface needed.

Features

• CalDAV Resources — Rooms show up in Nextcloud Calendar, Apple Calendar, Outlook, eM Client, Thunderbird
• Auto-accept / Approval workflow — Per-room setting: instant confirmation or manager approval
• Conflict detection — Automatic overlap checking, conflicting bookings are declined
• Permission system — Viewer / Booker / Manager roles per room, user and group based
• Room groups — Organize rooms into groups with shared permissions
• Availability rules — Restrict booking hours per room (e.g., weekdays 08:00–18:00)
• Booking horizon — Limit how far in advance rooms can be booked
• Email notifications — Booking confirmations, decline notices, approval requests with iCalendar attachments
• Per-room SMTP — Each room can have its own SMTP config (passwords encrypted via ICrypto)
• Custom room types — Define and manage room types (meeting room, studio, lecture hall, etc.)
• Public REST API — Bearer token API for external integrations (displays, kiosks, digital signage)
• CSV Import/Export — Bulk room management, with MS365/Exchange format support
• Client compatibility — Fixes for iOS (CUTYPE=INDIVIDUAL) and eM Client (LOCATION-only booking)
• No database — All configuration stored via Nextcloud's IAppConfig

Installation

From Nextcloud App Store

1. Go to Apps in your Nextcloud instance

3. Click Install

From Source

# Clone into Nextcloud apps directory
cd /var/www/nextcloud/apps/
git clone https://github.com/nextcloud/RoomVox.git roomvox

# Install PHP dependencies
cd roomvox
composer install --no-dev

# Build frontend
npm ci
npm run build

# Enable the app
sudo -u www-data php /var/www/nextcloud/occ app:enable roomvox

Prerequisites

• SMTP must be configured in Nextcloud (Settings > Administration > Basic settings > Email server)
• sendInvitations must be enabled for iMIP calendar invitations:

How It Works

1. Admin creates rooms via the admin panel (Settings > Administration > RoomVox)
2. Rooms appear as bookable resources in any CalDAV-compatible calendar app
3. Users book rooms by adding them to calendar events
4. RoomVox handles everything — scheduling, conflict detection, permissions, and notifications
