There are a few things to consider and the below points should provide you with basic guidance to help you to make a decision depending on your system requirements.
Host your system with 3CX:
We manage the 3CX operating system and updates, as well as monitor your 3CX system 24/7.
You will need to pay the subscription cost + hosting for the 16SC instance.
The perpetual license would need to be converted into an annual subscription first. The maintenance must be valid in order to request the conversion, and the email would need to be sent to [email protected] by the registered owner.
If you would like to check more in-depth details and options particular to your current license, please feel free to reach out to the CSR team at [email protected].
