Update - Telephony quality issues

Resolution of the telephony quality issues that have existed since November 18, 2025, 3:40 p.m.

Thanks to our targeted optimization measures in collaboration with an external service provider, we were able to improve all systems associated with telephony so that you once again have access to a high-quality telephone connection.

If further disruptions occur, these are often not attributable to the telephone system itself. Rather, they frequently arise from individual usage scenarios, such as connection issues with Wi-Fi in the home office or problems with volume control, e.g., on the monitor. We therefore recommend checking your local environment.

If you still need support, please create a ticket in the Service Desk and describe the details of your environment: place of work (office or home office), device used (phone/PC), exact time of the incident, and whether it was an internal or external call.

Thank you for your patience and understanding.
