# Presence Status

In the context of the Universität Greifswald telephony system, **Presence Status** refers to the real-time indication of a user's current telephony state. This information is visible to other users within the same organizational unit via the [[telefonportal]].

## Status Types
The system signals the following states:
- **Free**: The participant is available for calls.
- **Busy**: The participant is currently engaged in a call.
- **Forwarded**: The phone is set to redirect calls to another destination.
- **Logged off**: The participant is disconnected or signed off from the telephone system.

## Visibility and Access
Presence status is accessible through two primary interfaces in the [[telefonportal]]:
1. **Participant Overview**: A dedicated column showing all members of the user's organizational unit.
2. **Search Mask**: Status information is displayed when searching for a specific individual.

## Legal Basis
The monitoring of presence status is legally grounded in **§3 Abs. 6 of the Service Agreement** (*Dienstvereinbarung über den Einsatz eines Telekommunikationssystems und die Nutzung der mobilen Telefonie*) to ensure transparency and compliance with data privacy regulations.
