Update - Quality problems
Disrupted – Resolved after 70d 18h 58m
Updated:Fixing the quality problems in telephony that have existed since 18.11.2025, 15:40.
Through our targeted optimization measures in cooperation with an external service provider, we have been able to improve all systems connected to telephony in such a way that a high-quality telephone connection is now available to you again.
If further incidents occur, these are often not due to the telephone system itself. Rather, they often arise through individual usage scenarios, such as connection problems in WLAN in the home office or problems with volume control e.g. on the monitor. We therefore recommend checking the respective environment variables.
Should However, you need support, please create a ticket in the Service Desk and describe the details of your environment: office or home office, device used (telephone/PC), exact time of the incident and whether it is an internal or external telephone.
We thank you for your patience and understanding.
