# Telefonportal

The **Telefonportal** is a central web-based management interface provided by the [[universitatsrechenzentrum-urz]] for the configuration and operation of the university's telephone system and telephony services. It is used by members of the Universität Greifswald to configure their telephony end-devices, manage their assigned phone numbers, adjust telephony settings, and monitor the status of other participants.

## Access and Authentication
- **URL**: `https://portal.tk.uni-greifswald.de`
- **Authentication**: Access is secured via [[shibboleth]].

## Features and Functionality
The portal enables self-service management of telephony functions and device settings.

### General Management
- **Call Management**: Viewing and deleting call lists, and initiating calls directly from the web browser.
- **Configuration**: Setting up call forwarding (Rufumleitungen) and assigning function keys.
- **Faxing**: Sending faxes through an [[elektronische-faxbox]].
- **Account Management**: Access to the [[my-ipbx]] area for number configuration.
- **Multi-Number Support**: Integration of multiple phone numbers via the [[quickswitch]] feature (detailed in [[quickswitch]]).

### Participant Monitoring and Search
- **Participant Overview (Teilnehmerübersicht)**: Provides a real-time list of all participants within the user's organizational unit, displaying their [[presence-status]].
- **Search**: A search mask that allows users to find colleagues and view their current telephony status.

### User Interface and Customization
- **Interface**: The portal utilizes a red sidebar for primary navigation and account selection.
- **Ringtone Management**: Users can change the device ringtone via the **Settings** (Einstellungen) tab.

#### Ringtone Customization
Users cannot upload custom ringtones directly to the portal. Instead, they must select from a library of approved ringtones maintained by the [[universitatsrechenzentrum-urz]]. 

The library can be expanded upon request if the submitted audio file meets the following criteria:
- **Copyright**: Must be GEMA- and license-free (proof required).
- **Duration**: Maximum 5 seconds.
- **Format**: WAV or MP3.

## Operational Warning: Session Timeout
Users are cautioned regarding the automatic logout process. After a period of inactivity, the system redirects the user to a login form. The URZ explicitly instructs users **not to use this redirected login form** for re-authentication.

## Support
Technical support for the Telefonportal is provided by the [[universitatsrechenzentrum-urz]] via:
- The [[groupware]] ticket system.
- The URZ central hotline (extension 1420).
