# Telephony - Telecommunications Service

This source describes the centralized telecommunications service provided by the Universitätsrechenzentrum (URZ) for the Universität Greifswald. It outlines the legal framework, the categorization of phone numbers, and the support channels available for telephony issues.

## Key Information
- **Service Provider**: The URZ provides the central telephone system.
- **Legal Framework**: Usage is governed by the "Dienstvereinbarung über den Einsatz eines Telekommunikationssystems und die Nutzung der mobilen Telefonie an der Universität Greifswald".
- **Support**: Technical issues are handled via the [[groupware]] ticket system or the URZ hotline (ext. 1420).

## Number Categorization
The URZ strictly distinguishes between two types of phone numbers:
1. **Personal Phone Numbers**: Support private calls and feature automatically maintained display names.
2. **Functional Phone Numbers**: Used for roles or locations (e.g., labs). They cannot be used for private calls, cannot be moved between devices, and require at least two designated responsible persons.

## Available Features
The service includes a **Telefonportal** (Telephone Portal), call forwarding (Rufumleitung), and tools for printing button labels (Tastenbeschriftung). It also covers mobile data and handsets.
