Comply with the notes of the server manufacturer.

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.

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

Consistently use all available options for assigning passwords and PINs. Do not use passwords and PINs that are easy to guess, such as birthdays or anniversaries.

Use the available permissions (programming authorisation, exchange line authorisations, restricted numbers, etc.).

Regularly check 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).
