# DFNconf / Pexip Web Conferencing Service

This source provides technical and operational details for the DFNconf service provided by the DFN (Deutsches Forschungsnetz) and supported by the URZ at Universität Greifswald.

## Service Overview
DFNconf uses **Pexip** as its central web-based interface. It supports multiple connection methods:
- **WebRTC** (via browser or dedicated Pexip Apps)
- **H.323 / SIP** (classic video conferencing systems)
- **Telephone dial-in**

## Technical Constraints and Limits
- **Participant Capacity**: Supports up to **23 active video participants** and **50 active audio participants**.
- **Session Lifecycle**: 
    - Guest transmissions only begin once a **Host** (Veranstalter) enters the room.
    - The conference automatically terminates for all participants **10 minutes** after the last Host leaves.
- **Video Visibility**: To see other participants' video, a user must either send their own video signal or use the alternative web client (`conf.dfn.de/webapp/`).

## User Roles and Access
- **Roles**: The system distinguishes between **Hosts** (Veranstalter) and **Guests**, with different permissions based on conference configuration.
- **Host Login**: Managed via [[shibboleth]] at `my.conf.dfn.de`.
- **Web Client**: Accessible at `conf.dfn.de/webapp/`.

## Client Configuration
Local Pexip clients can be provisioned/branded via a specific API link provided by the service to unlock full functionality, such as layout control.

## Data Protection and Policy
- **Recording Prohibition**: The use of **recording** and **upload** functions within DFNconf is **strictly prohibited** for data privacy/protection reasons.
- **Recommended Alternative**: Users who require recording or upload capabilities are directed to use [[bigbluebutton]].
