If you once purchased a 3CX license, but for some reason decided not to update it, now such an outdated system should be used very carefully. The fact is that in order to activate the license and download updates, 3CX uses SSL certificates certifying, in particular, that you are actually downloading files from the developer, and not “fake” files, for example, it is the distributors of the Petya virus.
 
 
However, the validity of these certificates both on 3CX servers and on your systems, if they have not been updated, has come to an end. The problem is further complicated by the fact that the certification authority, which once issued 3CX certificates, cannot extend them due to technical disagreements with Google and other market players.
 
 
To solve this problem, 3CX offered absolutely all users of previous versions of 3CX to upgrade to the latest version for free. In fact, you received a multi-year subscription to updates as a gift! Distribution of proposals was carried out within two months by e-mail addresses specified during activation of the license. All that was required to do was to go step by step with your version of the system to the last via backup.
 
 
However, all this was true until October 3? 2018. Now we must be especially careful. What happens if you still have not updated to v15.5 Update 6? Your system will continue to work as before, but you will not be able to activate the license if the activation suddenly “flies”. The activation of 3CX is bound, first of all, to the MAC address of the network card, but also to other server parameters. Therefore, in such a situation it is extremely important not to reinstall 3CX, and not to change the server configuration! Your 3CX will no longer be able to activate and will switch to the free edition mode (for the version of 3CX that you have installed). In fact, your telephony will “stop”. utility , unzip the files and run 3CX WinUpdater.exe as an administrator.
 
 
 
 
Depending on the number of required updates, PBX services will be restarted several times. The update process is displayed on the Windows command line. Do not close this window!
