Current: 07.05.2020 Disturbance in QIP

Since today, May 7, 2020, there are some problems with changing IPv4 objects in the IP address management system QIP. The message "Fail to Safe" appears.

We are working together with the manufacturer to solve the problem.

As a workaround it can help to select the DHCP tab once after the message and go back to the Object tab and save again.

Maintenance (Update): 13.05.2020 - IP-Telephone System

The registration to Jabber is still not possible in some cases. Users affected by this problem can alternatively set up a call forwarding via the Self Service Portal ( This is now available again.

Together with the manufacturer, we are still working on solving the problem as quickly as possible.


Some phones are not yet registered and display a message to that effect. In such a case, the phones can be briefly disconnected from the power supply (pull the network cable), in which case they should also register.

No changes can be made on at the moment. The internal Jabber registration is also not yet reliably possible.

We are therefore still working on a solution to the problem.


On Wednesday, 13.05.2020, maintenance work will be carried out on the IP telephone system between 6:00h and 8:00h.

The IP phones will re-register several times and some will load new software. The phones must not be disconnected from the network during this time. An interruption of active calls is not expected, but cannot be completely excluded.

ISDN and analogue telephones are not affected by the maintenance work.

Reason for the maintenance are necessary updates.

Current: 10.03.2020 - Partial Malfunction of the Atlassian Tool Confluence

Currently we observe problems when editing web sites using the Atlassian Wiki Tool Confluence ( This means, if a page is saved you won't get the same page later again but some random previous version of it, so changes are lost.

Therefore, please check the page content of a revised version with the content of the updated version before you save the page.

The reason is a bug of the collaborative editing in the Atlassian Wiki tool Confluence. We are working on a solution to this problem together with the manufacturer.
