Since July, a certificate exchange has been made on all operating telephone sets.
All devices that were not connected during the certificate exchange can no longer be operated, are removed from the telephone system and are thus no longer functional.
The expenses for telephone sets are currently not charged to the structural elements (organizational units).
We would like to point out expressly that the storage of telephone sets by structural elements (organizational units) must not take place, since thereby significant costs arise through additionally needed apparatuses.
Please bring unnecessary or non-functioning telephone sets to the service center of TU.it Operngasse 11.
