How it works

1. Create rooms

Administrators create rooms through the admin panel with capacity, facilities and availability rules.

2. Book via your calendar

Users book rooms directly from their favorite calendar app. The room appears as a bookable resource.

3. Confirmation or approval

Bookings are automatically confirmed or forwarded to a manager for approval.

Works with any calendar app

RoomVox uses the standard CalDAV protocol. Rooms automatically appear as bookable resources in any compatible calendar app.
