Licences
The operation of the system requires mandatory (Exception: Tryout mode) initialisation and the purchasing of the following licences:
•System activation (only hardware variants)
*Further help under COMtrexx hardware variants
•one or more user licenses
In addition, further licences can be purchased:
•PBX Call Assist V1
User licences are offered in the form of floating user licences.
*For more information on floating user licenses, take a look at the Auerswald EULA. You will find this in the Internet under: Auerswald Support/FONtevo Support or here: Dashboard > Status information > Legal > End User License Agreement for Software (EULA)
*For initialisation during initial setup, take a look at the Instructions of your COMtrexx variation. You will find this in the Internet under: Auerswald Support/FONtevo Support.
The PBX regularly carries out a verification of the licences purchased and the legal activation. An overview of the licences purchased as well as links to the shop and tools for reinitialisation can be found here:Administration > Licences
*Important: The PBX requires access to the CIC server/server of the Voucher Center for verification. Make sure that the address and port are reachable.
*Further help under Network
*For more information on data exchange with the CIC server and the server of the Voucher Center, take a look at the Privacy Policy of the COMtrexx. You will find this in the Internet under: Auerswald Support/FONtevo Support or here: Dashboard > Status information > Legal > Data protection
Tryout Mode 
The 14-day tryout mode enables a COMtrexx VM to be tested without the purchase of licences. In tryout mode, three user test licences are available for setting up users, which must be relicenced when exiting or expiring tryout. If more than three users are required, this requires the purchase of licences. Further use of the tryout mode ist then not possible.
*Note: There is no tryout mode available for the hardware variants. These PBXs always require the purchase of licences.
*Further help under COMtrexx hardware variants
