# Ringtone Customization

Ringtone customization at the Universität Greifswald is a managed process where the [[universitatsrechenzentrum-urz]] controls the available audio assets to ensure legal compliance and technical compatibility.

## Process
Users perform customization through the [[telefonportal]] by navigating to the **Settings** (Einstellungen) tab and selecting a ringtone from the provided list.

## Submission Policy for New Ringtones
Because users cannot upload files directly, they must request the addition of new tones. The URZ enforces a strict policy for these requests:

### Legal Requirements
- **License-Free**: The file must be free of GEMA and other license costs.
- **Copyright**: No restrictive copyright conditions may apply.
- **Proof**: The requester is responsible for providing evidence of the file's legal status.

### Technical Requirements
- **Length**: The audio clip must not exceed 5 seconds.
- **Format**: Only WAV or MP3 files are accepted.
