Fully digital …

is the new telephone system of ISW GmbH. In the course of digitalisation, the previous system was replaced by a new fully digital system that offers all currently useful possibilities.

In this context, unfortunately, the previous telephone numbers had to be changed. In future you can reach our head office under

04121 26431 20
04121 26431 21 (fax)

Your contact persons can also be reached at 04121 26431 – xx, you will find the respective extension in the mail signatures of the colleagues.

Don’t worry: for a longer period of time, the previous telephone numbers will continue to be available and will be redirected to the new numbers. But please enter the new numbers in your directory from time to time.

We look forward to your calls!
