To ensure that you are able to use the COMtrexx VM safely and without faults, comply with the notes below. Improper use may, for example, cause functional restrictions, destruction of the device or, in a worst case scenario, personal injury. You will find any necessary additional warning notices about using the device in the relevant sections.

Read the instructions for the device and keep them for future reference.

Incomplete or incorrect configuration can create a personal hazard e.g. because emergency calls cannot be made.

The configuration of the product is made via an integrated web server whose pages are called via web browser. The user interface of the web server (web interface) is available in German, English and French. The detailed operating instructions (online help) is provided in German and English. If you are not familiar with these languages, and the technical terms that are used, seek support from someone who has the necessary technical and language skills.

Take suitable measures for protecting your data and the PBX against misuse.

Make consistent use of all the options offered by the PBX to protect against misuse. This includes the assignment of PINs and passwords, the use of multi-factor authentication (MFA) and the sensible use of the available authorisations (programming authorisation, office routing, etc.)

Never tell anyone the user names, passwords, PINs or secret keys. This applies to postings in forums and communities, router service logs or recorded network protocols.

Regularly check the system events and the call data recording of your COMtrexx and, if necessary, the logs of your NAT router for discrepancies.

Additional information about protecting the system from misuse can be found in the internet on the pages of the German Federal Office for Information Security (see www.bsi.bund.de search text: TK-Anlagen).
